Virtual Private LAN Service is already very popular among the enterprise industry which is a point to point network or multipoint to multipoint l2VPN service, VPLS provides transparent bridge between customers connected to geographically dispersed locations delivered via MPLS backbone by utilizing features such as MPLS Fast reroute and traffic engineering. Redundant paths can be applied to the VPLS service on the access side and backbone to maintain link performance that aims to minimize down time during network fails on the VPLS service. In this research, the implementation of redundant path using RSTP to prevent forwarding loop switching network in VPLS service to protect end-to-end data traffic with VPLS mesh-pseudowire and spoke-pesudowire with RSTP is the most optimal result compared to STP and build reliable network System with high performance for use in modern industry.

This paper focuses on the performance of basic communication primitives, namely the overlap of message transfer with computation in the point-to-point communication within a small cluster of four nodes. The mpptest has been implemented to measure the basic performance of MPI message passing routines with a variety of message sizes. The mpptest is capable of measuring performance with many participating processes thus exposing contention and scalability problems. This enables programmers to select message sizes in order to isolate and evaluate sudden changes in performance. Investigating these matters is interesting in that non-blocking calls have the advantage of allowing the system to schedule communications even when many processes are running simultaneously. On the other hand, understanding the characteristics of computation and communication overlap is significant, because high- performance kernels often strive to achieve this, since it is both advantageous with respect to data transfer and latency hiding. The results indicate that certain overlap sizes utilize greater node processing power either in blocking send and receive operations or non-blocking send and receive operations. The results have elucidated a detailed MPI characterization of the performance regarding the overlap of message transfer with computation in a small cluster system.

Drug Receptor

In the search for new drug and medication discovery, especially related to drug-receptor interaction, the importance of interaction among researchers is essential, either within the same room or dispersed throughout the world. The interaction in an online environment through the molecule shared view and information and ideas exchange via text and/or voice enable researchers to discuss molecule aspects under study, increasing the chances of reaching the new compound’s identification. In subsequent sections an architecture that uses concepts of Distributed Multiuser Virtual Reality, Computer-Supported Collaborative Work, and world-wide network communication techniques for creating a high performance system that allows real-time interaction among various geographically dispersed research groups studying molecular visualization and using hardware systems ranging from desktop to immersive systems as CAVEs is presented. Its construction was made possible by defining a structure based on local servers to each group, which communicate with each other on a remote network, and creating a protocol for communication among these servers that seeks agility to minimize the negative effects of packet loss and delay delivery, Internet characteristic problems.

Effective Channel

In the past several decades, we have seen tremendous advancements in the development of communication technology. Since the invention of the Internet in 1969, there has been rapid development of Internet-based communication tools and technologies. This technology has revolutionized business practices by offering another important and effective channel for communication (Foo & Lim, 1997) and has allowed people to work on projects irrespective of their physical location. One resulting business practice that has been adopted in recent years is virtual teamwork. Virtual teams are groups of individuals who work together in different locations (i.e., are geographically dispersed), work at interdependent tasks, share responsibilities for outcomes, and rely on technology for much of their communication (Cohen & Gibson, 2003). The use of virtual teams has become widespread in organizations, and its use is expected to grow (Martins, Gilson, & Maynard, 2004; Powell, Piccoli, & Ives, 2004).

New Challenges

The continuous growth in the Internet’s size, the amount of data traffic, and the complexity of processing this traffic give rise to new challenges in building high performance network devices. Such an exponential growth, coupled with the increasing sophistication of attacks, is placing stringent demands on the performance of network Information Systems. These challenges require new designs, architecture, and algorithms for raising situational awareness, and hence, providing performance improvements on current network devices and cyber systems. In this research, the author focuses on the design of architecture and algorithms for optimization of network defense systems, specifically firewalls, to aid not only adaptive and real-time packet filtering but also fast content based routing (differentiated services) for today’s data-driven networks.
