Using Emergent Team Structure to Focus Collaboration
Using Emergent Team Structure to Focus Collaboration by Shawn Minto B.Sc, The University of British Columbia, 2005 A THESIS SUBMITTED IN PARTIAL FULFILMENT OF THE REQUIREMENTS FOR THE DEGREE OF Master of Science The Faculty of Graduate Studies (Computer Science) The University Of British Columbia January 30, 2007 © Shawn Minto 2007 ii Abstract To build successful complex software systems, developers must collaborate with each other to solve issues. To facilitate this collaboration specialized tools are being integrated into development environments. Although these tools facilitate collaboration, they do not foster it. The problem is that the tools require the developers to maintain a list of other developers with whom they may wish to communicate. In any given situation, it is the developer who must determine who within this list has expertise for the specific situation. Unless the team is small and static, maintaining the knowledge about who is expert in particular parts of the system is difficult. As many organizations are beginning to use agile development and distributed software practices, which result in teams with dynamic membership, maintaining this knowledge is impossible. This thesis investigates whether emergent team structure can be used to support collaboration amongst software developers. The membership of an emergent team is determined from analysis of software artifacts. We first show that emergent teams exist within a particular open-source software project, the Eclipse integrated development environment. We then present a tool called Emergent Expertise Locator (EEL) that uses emergent team information to propose experts to a developer within their development environment as the developer works. We validated this approach to support collaboration by applying our ap• proach to historical data gathered from the Eclipse project, Firefox and Bugzilla and comparing the results to an existing heuristic for recommending experts that produces a list of experts based on the revision history of individual files. -

This is important in a wide range of applications, from plugin-based end user applications to critical applications with high availability requirements. Dynamic component-based platforms allow software to evolve at runtime, by allowing components to be loaded, and executed without forcing applications to be restarted. However, the flexibility of such mechanism demands applications to cope with errors due to inconsistencies in the update process, or due to faulty behavior from components introduced during execution. This is mainly true when dealing with third-party components, making it harder to predict the impacts (e.g., runtime incompatibilities, application crashes) and to maintain application dependability when integrating such third-party code into the application. -
Distributed Computing Network System, Said to Be "Distributed" When the Computer Programming and the Data to Be Worked on Are Spread out Over More Than One Computer
Praveen Balda et al, International Journal of Computer Science and Mobile Computing, Vol.4 Issue.4, April- 2015, pg. 761-767 Available Online at www.ijcsmc.com International Journal of Computer Science and Mobile Computing A Monthly Journal of Computer Science and Information Technology ISSN 2320–088X IJCSMC, Vol. 4, Issue. 4, April 2015, pg.761 – 767 RESEARCH ARTICLE Security Enhancement in Distributed Networking Praveen Balda, Sh. Matish Garg Distributed Networking is a distributed computing network system, said to be "distributed" when the computer programming and the data to be worked on are spread out over more than one computer. Usually, this is implemented over a network. Prior to the emergence of low-cost desktop computer power, computing was generally centralized to one computer. Although such centers still exist, distribution networking applications and data operate more efficiently over a mix of desktop workstations, local area network servers, regional servers, Web servers, and other servers. One popular trend is client/server computing. This is the principle that a client computer can provide certain capabilities for a user and request others from other computers that provide services for the clients. (The Web's Hypertext Transfer Protocol is an example of this idea.) Enterprises that have grown in scale over the years and those that are continuing to grow are finding it extremely challenging to manage their distributed network in the traditional client/server computing model. The recent developments in the field of cloud computing has opened up new possibilities. Cloud-based networking vendors have started to sprout offering solutions for enterprise distributed networking needs. -

The Raincore Distributed Session Service for Networking Elements
The Raincore Distributed Session Service for Networking Elements Chenggong Charles Fan Jehoshua Bruck California Institute of Technology Mail-Stop 136-93 Pasadena, CA 91125 {fan, bruck}@paradise.caltech.edu Abstract devices naturally become key challenges facing the Internet infrastructure today. Motivated by the explosive growth of the Internet, we study efficient and fault-tolerant distributed session layer Networking protocols for networking elements. These protocols are elements Server2 Data designed to enable a network cluster to share the state information necessary for balancing network traffic and Server1 computation load among a group of networking elements. In addition, in the presence of failures, they allow Firewall network traffic to fail-over from failed networking Router elements to healthy ones. To maximize the overall network throughput of the networking cluster, we assume a unicast communication medium for these protocols. Router The Raincore Distributed Session Service is based on a fault-tolerant token protocol, and provides group Internet membership, reliable multicast and mutual exclusion Client Proxy Server services in a networking environment. We show that this service provides atomic reliable multicast with consistent ordering. We also show that Raincore token protocol Figure 1. An example of a traffic path consumes less overhead than a broadcast-based protocol between a client and a server farm. in this environment in terms of CPU task-switching. The Raincore technology was transferred to Rainfinity, a startup company that is focusing on software for Internet One promising way of improving the reliability and reliability and performance. Rainwall, Rainfinity’s first performance of the Internet is to cluster the networking product, was developed using the Raincore Distributed elements. -

P2P Group Management Systems: a Conceptual Analysis
P2P Group Management Systems: A Conceptual Analysis TIMO KOSKELA, OTSO KASSINEN, ERKKI HARJULA, and MIKA YLIANTTILA, University of Oulu Peer-to-Peer (P2P) networks are becoming eminent platforms for both distributed computing and interper- sonal communication. Their role in contemporary multimedia content delivery and communication systems is strong, as witnessed by many popular applications and services. Groups in P2P systems can originate from the relations between humans, or they can be defined with purely technical criteria such as proximity. In this article, we present a conceptual analysis of P2P group management systems. We illustrate how groups are formed using different P2P system architectures, and analyze the advantages and disadvantages of using each P2P system architecture for implementing P2P group management. The evaluation criteria in the analysis are performance, robustness, fairness, suitability for battery-powered devices, scalability, and security. The outcome of the analysis facilitates the selection of an appropriate P2P system architecture for implementing P2P group management in both further research and prototype development.
