Recently, simulation has became the most effective way for analyzing and perfecting the performance of telecommunication networks. It has proven itself as the best method in the realm of education, where the hardware capabilities for practical training are often limited. A simulated network enables students to practice hands-on network programming and to understand, in a practical way, how a data communication network operates and how protocols work.Metanet is an environment that enables the programmer to write networking applications and to test them as if using an IP network with the hosts connected through Ethernet. The whole software is a multi-process application that makes use of just the resources offered by a single machine. It runs on a UNIX system and emulates hosts that also communicate through an emulated network using TCP/IP. Each layer of the hosts' operating system is designed as a separate process that will communicate with the adjacent layers using socket pairs or UDP connections. The application layer has multi-processing capability. / Department of Computer Science

Software emulation of local area and wide area networks provides an alternative method for the design of such networks and for analyzing their performance. Emulation of bridges and routers that link networks together may provide valuable information regarding network congestion, network storms and the like before putting expensive hardware into place. Such an emulation also enables students taking a networking course to develop their own client-server applications and to visualize the basic functioning of the UDP/IP and RIP protocols.This thesis builds on the emulated local area network, Metanet, created by a previous graduate student. It adds the capability of attaching routers and bridges to multiple local and non-local emulated networks so that data may be transferred between two hosts on different segments of the same LAN (via an emulated bridge) or two different networks altogether (via an emulated router). The machines running the Metanet software should support UNIX which has Berkeley's Socket interface as emulated networks on different physical machines utilize this interface for communicating. A comparison of the new networking capabilities of Metanet and other experimental systems like XINU and MINIX is researched. / Department of Computer Science

One of the local area network medium access control standards created by the Institute of Electrical and Electronic Engineers in IEEE Project 802 is the carrier sense multiple access with collision detection (CSMA/CD) medium access control. Numerous studies have been reported in the literature on the performance of CSMA/CD. These studies show that CSMA/CD performs well under light network load but not well at heavy load. To improve the performance of CSMA/CD under heavy load, a new concept called network partitioning is presented. Network partitioning allows the network to be partitioned into segments when under heavy load. Partition stations then act as bridges between the segments. The impact of network partitioning on network performance was tested using a simulation model of an Ethernet local area network (an implementation of the CSMA/CD medium access control). The simulation results show that network partitioning can improve the performance of CSMA/CD under heavy load.

Networks play an important role in today's information age. The need to share information and resources makes networks a necessity in almost any computing environment. In many cases, the network can be thought of as a large, distributed computer, with disks and other resources on big systems being shared by smaller workstations on people's desks.Security has long been an object of concern and study for both data processing systems and communications facilities. With computer networks, these concerns are combined, and for local networks, the problems may be more acute. Consider a fullcapacity local network, with direct terminal access to the network, data files, and applications distributed among a variety of processors. This network may also provide access to and from long-haul communications and be part of an internet. Clearly, the task of providing security in such a complex environment is quite involved.The subject of security is a broad one and encompasses physical and administrative controls. The aim of this research is to explore the security problems pertaining to Ethernet networks. Different approaches to obtain a secure Ethernet environment are also discussed. / Department of Computer Science
