TL;DR: A networking lab that can solve the problems of funding for the hardware facility, physical space limitations, and physical accessibility of the lab facility is designed.
Abstract: College students in computer networking courses are very interested in Internet technology because of the rapid growth in that area. Of particular interest is the need for practical experience in network design and configuration. A typical computer networking class curriculum includes the study of theory and the laboratory projects. The laboratory projects are designed to give students a better understanding of computer networks. Most of the laboratory projects are software projects. Furthermore it is common to find projects in the area of implementing an application layer protocol and protocol observations in many computer network course textbooks [7,11,12]. However, having a networking laboratory with the proper hardware facilities to teach real networking has several difficulties. These difficulties include funding for the hardware facility, physical space limitations, and physical accessibility of the lab facility [6,10]. We have designed a networking lab that can solve these problems. Old PCs have been converted to IP routers with the free router software Zebra [5]. The proposed laboratory system can be accessed through the Internet, and the network topology can be changed remotely.

TL;DR: In this paper, a common media access control layer accesses different media of the backbone network and integrates a number of networking media elements of different multimedia data types interconnected by the networking system.
Abstract: A networking system includes wired and/or wireless LANs connected to a virtual access point including a backbone network, wired-to-backbone bridges, and wireless-to-backbone bridges. A common media access control layer accesses different media of the backbone network and integrates a number of networking media elements of different multimedia data types interconnected by the networking system.

TL;DR: The networking subsystem overhead for high-performance networking and the current operating system techniques to address the overhead are surveyed and a few directions for future research work are identified.
Abstract: Crucial applications require direct and efficient access to emerging high-performance networks. This paper surveys the networking subsystem overhead for high-performance networking and the current operating system techniques to address the overhead. This paper aims to identify a few directions for future research work.

TL;DR: As the networking community explores Abilene's perils and possibilities, some researchers have raised questions about the Internet2 organization itself, saying that although Internet2 generally does a great job of bringing together high-end networking enthusiasts, the organization can sometimes be lax in particular policy areas.
Abstract: Internet2 products are now indispensable in the research environment. Over 200 US universities lead Internet2, a not-for-profit consortium with many projects in the works. For the networking community, the centerpiece is Abilene, a networking infrastructure available to consortium members. Already very fast and very high-performance, Abilene is being upgraded. Soon it should be able to move data at 10 Gbits per second - four times its previous capacity and about 10 thousand times faster than most computer networks used today. Even as the networking community explores Abilene's perils and possibilities, some researchers have raised questions about the Internet2 organization itself. They say that although Internet2 generally does a great job of bringing together high-end networking enthusiasts, the organization can sometimes be lax in particular policy areas

TL;DR: This document shows the basic internals of the networking code of Linux kernel and discusses the efficiency of the existing implementation in the 2.6 version.
Abstract: The fast evolution and increase in use of nowadays networks forces researchers to look for efficient ways of managing all the information that travels through those networks. Added to that, the growing use of Linux as main operating system for servers and big grid computing farms, has developed many research lines for increasing the networking capabilities and efficiency of the kernel code.Having that in mind, this document shows the basic internals of the networking code of Linux kernel and discusses the efficiency of the existing implementation in the 2.6 version. Besides, various tests are done for detecting existing bottlenecks in the networking core. Finally are also exposed guidelines for improving certain aspects of the kernel networking behaviour.

TL;DR: This research project covered three areas: to create an architecture and implementation for Innovative Active Networking Services based on Composite Protocols, establish criteria and evaluation measures for Active Network performance, and implement active networking services on end-point host systems based on the Windows NT and Linux operating systems.
Abstract: : Traditional networking implementations follow a layered protocol model that implements a well-defined protocol stack. Major functionality is built into the software and hardware of end-point hosts and the network switches and routers. The entire complex of end-point host system software, network switch software, and networking services evolves slowly due to the need to reach consensus prior to widespread changes and improvements in the protocols. Active Network was developed to bring robust, rapid flexibility to developing and deploying new network services and protocols. Our research project covered three areas: 1) Create an architecture and implementation for Innovative Active Networking Services based on Composite Protocols; 2) Established criteria and evaluation measures for Active Network performance; and 3) Implement Active Networking services on end-point host systems based on the Windows NT and Linux operating systems.
