forma Understanding ESB Performance & Benchmarking By pzf.fremantle.org Published On :: Tue, 18 Sep 2012 20:51:00 +0000 ESB performance is a hot (and disputed topic). In this post I don't want to talk about different vendors or different benchmarks. I'm simply trying to help people understand some of the general aspects of benchmarking ESBs and what to look out for in the results. The general ESB model is that you have some service consumer, an ESB in the middle and a service provider (target service) that the ESB is calling. To benchmark this, you usually have a load driver client, an ESB, and a dummy service. +-------------+ +---------+ +---------------+ | Load Driver |------| ESB |------| Dummy Service | +-------------+ +---------+ +---------------+ Firstly, we want the Load Driver (LD), the ESB and the Dummy Service (DS) to be on different hardware. Why? Because we want to understand the ESB performance, not the performance of the DS or LD. The second thing to be aware of is that the performance results are completely dependent on the hardware, memory, network, etc used. So never compare different results from different hardware. Now there are three things we could look at: A) Same LD, same DS, different vendors ESBs doing the same thing (e.g. content-based routing) B) Same LD, same DS, different ESB configs for the same ESB, doing different things (e.g. static routing vs content-based routing) C) Going via ESB compared to going Direct (e.g. LD--->DS without ESB) Each of these provides useful data but each also needs to be understood. Metrics Before looking at the scenarios, lets look at how to measure the performance. The two metrics that are always a starting point in any benchmark of an ESB here are the throughput (requests/second) and the latency (how long each request takes). With latency we can consider overall latency - the time taken for a completed request observed at the LD, and the ESB latency, which is the time taken by the message in the ESB. The ESB latency can be hard to work out. A well designed ESB will already be sending bytes to the DS before its finished reading the bytes the LD has sent it. This is called pipelining. Some ESBs attempt to measure the ESB latency inside the ESB using clever calculations. Alternatively scenario C (comparing via ESB vs Direct) can give an idea of ESB Latency. But before we look at the metrics we need to understand the load driver. There are two different models to doing Load Driving: 1) Do a realistic load test based on your requirements. For example if you know you want to support up to 50 concurrent clients each making a call every 5 seconds on average, you can simulate this. 2) Saturation! Have a large number of clients, each making a call as soon as the last one finishes. The first one is aimed at testing what the ESB does before its fully CPU loaded. In other words, if you are looking to see the effect of adding an ESB, or the comparison of one ESB to another under realistic load, then #1 is the right approach. In this approach, looking at throughput may not be useful, because all the different approaches have similar results. If I'm only putting in 300 requests a sec on a modern system, I'm likely to see 300 request a sec. Nothing exciting. But the latency is revealing here. If one ESB responds in less time than another ESB thats a very good sign, because with the same DS the average time per request is very telling. On the other hand the saturation test is where the throughput is interesting. Before you look at the throughput though, check three things: 1) Is the LD CPU running close to 100%? 2) Is the DS CPU running close to 100%? 3) Is the network bandwidth running close to 100%? If any of these are true, you aren't doing a good test of the ESB throughput. Because if you are looking at throughput then you want the ESB to be the bottleneck. If something else is the bottleneck then the ESB is not providing its max throughput and you aren't giving it a fair chance. For this reason, most benchmarks use a very very lightweight LD or a clustered LD, and similarly use a DS that is superfast and not a realistic DS. Sometimes the DS is coded to do some real work or sleep the thread while its executing to provide a more realistic load test. In this case you probably want to look at latency more than throughput. Finally you are looking to see a particular behaviour for throughput testing as you increase load. Throughput vs Load The shape of this graph shows an ideal scenario. As the LD puts more work through the ESB it responds linearly. At some point the CPU of the ESB hits maximum, and then the throughput stabilizes. What we don't want to see is the line drooping at the far right. That would mean that the ESB is crumpling under the extra load, and its failing to manage the extra load effectively. This is like the office worker whose efficiency increases as you give them more work but eventually they start spending all their time re-organizing their todo lists and less work overall gets done. Under the saturation test you really want to see the CPU of the ESB close to 100% utilised. Why? This is a sign that its doing as much as possible. Why would it not be 100%? Two reasons: I/O, multi-processing and thread locks: either the network card or disk or other I/O is holding it up, the code is not efficiently using the available cores, or there are thread contention issues. Finally its worth noting that you expect the latency to increase a lot under the saturation test. A classic result is this: I do static routing for different size messages with 100 clients LD. For message sizes up to 100k maybe I see a constant 2ms overhead for using the ESB. Suddenly as the message size grows from 100k to 200k I see the overhead growing in proportion to the message size. Is this such a bad thing? No, in fact this is what you would expect. Before 100K message size, the ESB is underloaded. The straight line up to this point is a great sign that the ESB is pipelining properly. Once the CPU becomes loaded, each request is taking longer because its being made to wait its turn at the ESB while the ESB deals with the increased load. A big hint here: When you look at this graph, the most interesting latency numbers occur before the CPU is fully loaded. The latency after the CPU is fully loaded is not that interesting, because its simply a function of the number of queued requests. Now we understand the metrics, lets look at the actual scenarios. A. Different Vendors, Same Workload For the first comparison (different vendors) the first thing to be careful of is that the scenario is implemented in the best way possible in each ESB. There are usually a number of ways of implementing the same scenario. For example the same ESB may offer two different HTTP transports (or more!). For example blocking vs non-blocking, servlet vs library, etc. There may be an optimum approach and its worth reading the docs and talking to the vendor to understand the performance tradeoffs of each approach. Another thing to be careful of in this scenario is the tuning parameters. Each ESB has various tuning aspects that may affect the performance depending on the available hardware. For example, setting the number of threads and memory based on the number of cores and physical memory may make a big difference. Once you have your results, assuming everything we've already looked at is tickety-boo, then both latency and throughput are interesting and valid comparisons here. B. Different Workloads, Same Vendor What this is measuring is what it costs you to do different activities with the same ESB. For example, doing a static routing is likely to be faster than a content-based routing, which in turn is faster than a transformation. The data from this tells you the cost of doing different functions with the ESB. For example you might want to do a security authentication/authorization check. You should see a constant bump in latency for the security check, irrespective of message size. But if you were doing complex transformation, you would expect to see higher latency for larger messages, because they take more time to transform. C. Direct vs ESB This is an interesting one. Usually this is done for a simple static routing/passthrough scenario. In other words, we are testing the ESB doing its minimum possible. Why bother? Well there are two different reasons. Firstly ESB vendors usually do this for their own benefit as a baseline test. In other words, once you understand the passthrough performance you can then see the cost of doing more work (e.g. logging a header, validating security, transforming the message). Remember the two testing methodologies (realistic load vs saturation)? You will see very very different results in each for this, and the data may seem surprising. For the realistic test, remember we want to look at latency. This is a good comparison for the ESB. How much extra time is spent going through the ESB per request under normal conditions. For example, if the average request to the backend takes 18ms and the average request via the ESB takes 19ms, we have an average ESB latency of 1ms. This is a good result - the client is not going to notice much difference - less than 5% extra. The saturation test here is a good test to compare different ESBs. For example, suppose I can get 5000 reqs/sec direct. Via ESB_A the number is 3000 reqs/sec and via ESB_B the number is 2000 reqs/sec, I can say that ESB_A is providing better throughput than ESB_B. What is not a good metric here is comparing throughput in saturation mode for direct vs ESB. Why not? The reason here is a little complex to explain. Remember how we coded DS to be as fast as possible so as not to be a bottleneck? So what is DS doing? Its really just reading bytes and sending bytes as fast as it can. Assuming the DS code is written efficiently using something really fast (e.g. just a servlet), what this is testing is how fast the hardware (CPU plus Network Card) can read and write through user space in the operating system. On a modern server hardware box you might get a very high number of transactions/sec. Maybe 5000req/s with each message in and out being 1k in size. So we have 1k in and 1k out = 2k IO. 2k IO x 5000 reqs/sec x 8bits gives us the total network bandwidth of 80Mbits/sec (excluding ethernet headers and overhead). Now lets look at the ESB. Imagine it can handle 100% of the direct load. There is no slowdown in throughput for the ESB. For each request it has to read the message in from LD and send it out to DS. Even if its doing this in pipelining mode, there is still a CPU cost and an IO cost for this. So the ESB latency of the ESB maybe 1ms, but the CPU and IO cost is much higher. Now, for each response it also has to read it in from DS and write it out to LD. So if the DS is doing 80Mbits/second, the ESB must be doing 160Mbits/second. Here is a picture. Now if the LD is good enough, it will have loaded the DS to the max. CPU or IO capacity or both will be maxed out. Suppose the ESB is running on the same hardware platform as the DS. If the DS machine can do 80Mbit/s flat out, there is no way that the same hardware running as an ESB can do 160Mbit/s! In fact, if the ESB and DS code are both as efficient as possible, then the throughput via ESB will always be 50% of the throughput direct to the DS. Now there is a possible way for the ESB to do better: it can be better coded than the DS. For example, if the ESB did transfers in kernel space instead of user space then it might make a difference. The real answer here is to look at the latency. What is the overhead of adding the ESB to each request. If the ESB latency is small, then we can solve this problem by clustering the ESB. In this case we would put two ESBs in and then get back to full throughput. The real point of this discussion is that this is not a useful comparison. In reality backend target services are usually pretty slow. If the same dual core server is actually doing some real work - e.g. database lookups, calculations, business logic - then its much more likely to be doing 500 requests a second or even less. The following chart shows real data to demonstrate this. The X-Axis shows increasing complexity of work at the backend (DS). As the effort taken by the backend becomes more realistic, the loss in throughput of having an ESB in the way reduces. So with a blindingly fast backend, we see the ESB struggling to provide just 55% of the throughput of the direct case. But as the backend becomes more realistic, we see much better numbers. So at 2000 requests a second there is barely a difference (around 10% reduction in throughput). In real life, what we actually see is that often you have many fewer ESBs than backend servers. For example, if we took the scenario of a backend server that can handle 500 reqs/sec, then we might end up with a cluster of two ESBs handling a cluster of 8 backends. Conclusion I hope this blog has given a good overview of ESB performance and benchmarking. In particular, when is a good idea to look at latency and when to use throughput. Full Article

forma Information Consolidation in Large Bodies of Information By www.jucs.org Published On :: 2011-03-18T16:21:18+01:00 Due to information technologies the problem we are facing today is not a lack of information but too much information. This phenomenon becomes very clear when we consider two figures that are often quoted: Knowledge is doubling in many fields (biology, medicine, computer science, ...) within some 6 years; yet information is doubling every 8 months! This implies that the same piece of information/knowledge is published a large number of times with small variations. Just look at an arbitrary news item. If considered of some general interest reports of it will appear in all major newspapers, journals, electronic media, etc. This is also the problem with information portals that tie together a number of large databases. It is our contention that we need methods to reduce the huge set of information concerning a particular topic to a number of pieces of information (let us call each such piece an "essay" in what follows) that present a good cross-section of potential points of view. We will explain why one essay is usually not enough, yet the problem of reducing a huge amount of contributions to a digestible number of essays is formidable, indeed is science fiction at the moment. We will argue in this paper that it is one of the important tasks of computer sciences to start tackling this problem, and we will show that in some special cases partial solutions are possible.

forma An Empirical Study on Human and Information Technology Aspects in Collaborative Enterprise Networks By www.jucs.org Published On :: 2011-07-08T12:30:00+02:00 Small and Medium Enterprises (SMEs) face new challenges in the global market as customers require more complete and flexible solutions and continue to drastically reduce the number of suppliers. SMEs are trying to address these challenges through cooperation within collaborative enterprise networks (CENs). Human aspects constitute a fundamental issue in these networks as people, as opposed to organizations or Information Technology (IT) systems, cooperate. Since there is a lack of empirical studies on the role of human factors in IT-supported collaborative enterprise networks, this paper addresses the major human aspects encountered in this type of organization. These human aspects include trust issues, knowledge and know-how sharing, coordination and planning activities, and communication and mutual understanding, as well as their influence on the business processes of CENs supported by IT tools. This paper empirically proves that these aspects constitute key factors for the success or the failure of CENs. Two case studies performed on two different CENs in Switzerland are presented and the roles of human factors are identified with respect to the IT support systems. Results show that specific human factors, namely trust and communication and mutual understanding have to be well addressed in order to design and develop adequate software solutions for CENs.

forma Coordinated System for Real Time Muscle Deformation during Locomotion By www.jucs.org Published On :: 2011-04-24T11:14:51+02:00 This paper presents a system that simulates, in real time, the volumetric deformation of muscles during human locomotion. We propose a two-layered motion model. The requirements of realism and real time computation lead to a hybrid locomotion system that uses a skeleton as first layer. The muscles, represented by an anatomical surface model, constitute the second layer, whose deformations are simulated with a finite element method (FEM). The FEM subsystem is fed by the torques and forces got from the locomotion system, through a line of action model, and takes into account the geometry and material properties of the muscles. High level parameters (like height, weight, physical constitution, step frequency, step length or speed) allow to customize the individuals and the locomotion and therefore, the deformation of the persons' muscles.

forma Context-Aware Composition and Adaptation based on Model Transformation By www.jucs.org Published On :: 2011-05-06T16:03:43+02:00 Using pre-existing software components (COTS) to develop software systems requires the composition and adaptation of the component interfaces to solve mismatch problems. These mismatches may appear at different interoperability levels (signature, behavioural, quality of service and semantic). In this article, we define an approach which supports composition and adaptation of software components based on model transformation by taking into account the four levels. Signature and behavioural levels are addressed by means of transition systems. Context-awareness and semanticbased techniques are used to tackle quality of service and semantic, respectively, but also both consider the signature level. We have implemented and validated our proposal for the design and application of realistic and complex systems. Here, we illustrate the need to support the variability of the adaptation process in a context-aware pervasive system through a real-world case study, where software components are implemented using Windows Workflow Foundation (WF). We apply our model transformation process to extract transition systems (CA-STS specifications) from WF components. These CA-STSs are used to tackle the composition and adaptation. Then, we generate a CASTS adaptor specification, which is transformed into its corresponding WF adaptor component with the purpose of interacting with all the WF components of the system, thereby avoiding mismatch problems.

forma A Framework to Evaluate Interface Suitability for a Given Scenario of Textual Information Retrieval By www.jucs.org Published On :: 2011-07-04T16:04:41+02:00 Visualization of search results is an essential step in the textual Information Retrieval (IR) process. Indeed, Information Retrieval Interfaces (IRIs) are used as a link between users and IR systems, a simple example being the ranked list proposed by common search engines. Due to the importance that takes visualization of search results, many interfaces have been proposed in the last decade (which can be textual, 2D or 3D IRIs). Two kinds of evaluation methods have been developed: (1) various evaluation methods of these interfaces were proposed aiming at validating ergonomic and cognitive aspects; (2) various evaluation methods were applied on information retrieval systems (IRS) aiming at measuring their effectiveness. However, as far as we know, these two kinds of evaluation methods are disjoint. Indeed, considering a given IRI associated to a given IRS, what happens if we associate this IRI to another IRS not having the same effectiveness. In this context, we propose an IRI evaluation framework aimed at evaluating the suitability of any IRI to different IR scenarios. First of all, we define the notion of IR scenario as a combination of features related to users, IR tasks and IR systems. We have implemented the framework through a specific evaluation platform that enables performing IRI evaluations and that helps end-users (e.g. IRS developers or IRI designers) in choosing the most suitable IRI for a specific IR scenario.

forma An Ontology based Agent Generation for Information Retrieval on Cloud Environment By www.jucs.org Published On :: 2011-07-20T10:35:16+02:00 Retrieving information or discovering knowledge from a well organized data center in general is requested to be familiar with its schema, structure, and architecture, which against the inherent concept and characteristics of cloud environment. An effective approach to retrieve desired information or to extract useful knowledge is an important issue in the emerging information/knowledge cloud. In this paper, we propose an ontology-based agent generation framework for information retrieval in a flexible, transparent, and easy way on cloud environment. While user submitting a flat-text based request for retrieving information on a cloud environment, the request will be automatically deduced by a Reasoning Agent (RA) based on predefined ontology and reasoning rule, and then be translated to a Mobile Information Retrieving Agent Description File (MIRADF) that is formatted in a proposed Mobile Agent Description Language (MADF). A generating agent, named MIRA-GA, is also implemented to generate a MIRA according to the MIRADF. We also design and implement a prototype to integrate these agents and show an interesting example to demonstrate the feasibility of the architecture. Full Article

forma The discussion of information security risk control in mobile banking By www.inderscience.com Published On :: 2024-10-02T23:20:50-05:00 The emergence of digital technology and the increasing prevalence of smartphones have promoted innovations in payment options available in finance and consumption markets. Banks providing mobile payment must ensure the information security. Inadequate security control leads to information leakage, which severely affects user rights and service providers' reputations. This study uses control objectives for Information and Related Technologies 4.1 as the mobile payment security control framework to examine the emergent field of mobile payment. A literature review is performed to compile studies on the safety risk, regulations, and operations of mobile payments. In addition, the Delphi questionnaire is distributed among experts to determine the practical perspectives, supplement research gaps in the literature, and revise the prototype framework. According to the experts' opinions, 59 control objectives from the four domains of COBIT 4.1 are selected. The plan and organise, acquire and implement, deliver and support, and monitor and evaluate four domains comprised 2, 5, 10, and 2 control objectives that had mean importance scores of > 4.50. Thus, these are considered the most important objectives by the experts, respectively. The results of this study can serve as a reference for banks to construct secure frameworks in mobile payment services. Full Article
forma Enhanced TCP BBR performance in wireless mesh networks (WMNs) and next-generation high-speed 5G networks By www.inderscience.com Published On :: 2024-07-01T23:20:50-05:00 TCP BBR is one of the most powerful congestion control algorithms. In this article, we provide a comprehensive review of BBR analysis, expanding on existing knowledge across various fronts. Utilising ns3 simulations, we evaluate BBR's performance under diverse conditions, generating graphical representations. Our findings reveal flaws in the probe's RTT phase duration estimation and unequal bandwidth sharing between BBR and CUBIC protocols. Specifically, we demonstrated that the probe's RTT phase duration estimation algorithm is flawed and that BBR and CUBIC generally do not share bandwidth equally. Towards the end of the article, we propose a new improved version of TCP BBR which minimises these problems of inequity in bandwidth sharing and corrects the inaccuracies of the two key parameters RTprop and cwnd. Consequently, the BBR' protocol maintains very good fairness with the Cubic protocol, with an index that is almost equal to 0.98, and an equity index over 0.95. Full Article
forma Design of intelligent financial sharing platform driven by consensus mechanism under mobile edge computing and accounting transformation By www.inderscience.com Published On :: 2024-07-02T23:20:50-05:00 The intelligent financial sharing platform in the online realm is capable of collecting, storing, processing, analysing and sharing financial data through the integration of AI and big data processing technologies. However, as data volume grows exponentially, the cost of financial data storage and processing increases, and the asset accounting and financial profit data sharing analysis structure in financial sharing platforms is inadequate. To address the issue of data security sharing in the intelligent financial digital sharing platform, this paper proposes a data-sharing framework based on blockchain and edge computing. Building upon this framework, a non-separable task distribution algorithm based on data sharing is developed, which employs multiple nodes for cooperative data storage, reducing the pressure on the central server for data storage and solving the problem of non-separable task distribution. Multiple sets of comparative experiments confirm the proposed scheme has good feasibility in improving algorithm performance and reducing energy consumption and latency. Full Article
forma Design of an intelligent financial sharing platform driven by digital economy and its role in optimising accounting transformation production By www.inderscience.com Published On :: 2024-07-02T23:20:50-05:00 With the expansion of business scope, the environment faced by enterprises has also changed, and competition is becoming increasingly fierce. Traditional financial systems are increasingly difficult to handle complex tasks and predict potential financial risks. In the context of the digital economy era, the booming financial sharing services have reduced labour costs and improved operational efficiency. This paper designs and implements an intelligent financial sharing platform, establishes a fund payment risk early warning model based on an improved support vector machine algorithm, and tests it on the Financial Distress Prediction dataset. The experimental results show that the effectiveness of using F2 score and AUC evaluation methods can reach 0.9484 and 0.9023, respectively. After using this system, the average financial processing time per order decreases by 43%, and the overall financial processing time decreases by 27%. Finally, this paper discusses the role of intelligent financial sharing platform in accounting transformation and optimisation of production. Full Article

forma Fostering innovative work behaviour in Indian IT firms: the mediating influence of employee psychological capital in the context of transformational leadership By www.inderscience.com Published On :: 2024-10-07T23:20:50-05:00 This empirical study investigates the mediating role of two components of psychological capital (PsyCap), namely self-efficacy and optimism, in the context of the relationship between transformational leadership (TL), work engagement (WE), and innovative work behaviour (IWB). The study was conducted among IT professionals with a minimum of three years of experience employed in Chennai, India. Data collection was executed using a Google Form, and both measurement and structural models were examined using SPSS 25.0 and AMOS 23.0. The findings of this study reveal several significant relationships. Firstly, transformational leadership (TL) demonstrates a robust positive association with work engagement (WE). Furthermore, work engagement (WE) positively correlates substantially with innovative work behaviour (IWB). Notably, the study underscores that two crucial components of psychological capital, specifically self-efficacy and optimism, mediate the relationship between transformational leadership (TL) and work engagement (WE). These findings carry valuable implications for IT company managers. Recognising that transformational leadership positively influences both work engagement and employees' innovative work behaviour highlights the pivotal role of leaders in fostering a productive and innovative work environment within IT organisations.

forma Applying a multiplex network perspective to understand performance in software development By www.inderscience.com Published On :: 2024-11-11T23:20:50-05:00 A number of studies have applied social network analysis (SNA) to show that the patterns of social interaction between software developers explain important organisational outcomes. However, these insights are based on a single network relation (i.e., uniplex social ties) between software developers and do not consider the multiple network relations (i.e., multiplex social ties) that truly exist among project members. This study reassesses the understanding of software developer networks and what it means for performance in software development settings. A systematic review of SNA studies between 1990 and 2020 across six digital libraries within the IS and management science domain was conducted. The central contributions of this paper are an in-depth overview of SNA studies to date and the establishment of a research agenda to advance our knowledge of the concept of multiplexity on how a multiplex perspective can contribute to a software developer's coordination of tasks and performance advantages.

forma The role of pre-formation intangible assets in the endowment of science-based university spin-offs By www.inderscience.com Published On :: 2024-09-02T23:20:50-05:00 Science-based university spin-offs face considerable technology and market uncertainty over extended periods of time, increasing the challenges of commercialisation. Scientist-entrepreneurs can play formative roles in commercialising lab-based scientific inventions through the formation of well-endowed university spin-offs. Through case study analysis of three science-based university spin-offs within a biotechnology innovation ecosystem, we unpack the impact of <i>pre-formation</i> intangible assets of academic scientists (research excellence, patenting, and international networks) and their entrepreneurial capabilities on spin-off performance. We find evidence that the pre-formation entrepreneurial capabilities of academic scientists can endow science-based university spin-offs by leveraging the scientists' pre-formation intangible assets. A theory-driven model depicting the role of pre-formation intangible assets and entrepreneurial capabilities in endowing science-based university spin-offs is developed. Recommendations are provided for scholars, practitioners, and policymakers to more effectively commercialise high potential inventions in the university lab through the development and deployment of pre-formation intangible assets and entrepreneurial capabilities.
