Mathematical modeling, performance analysis and simulation of current Ethernet computer networks

This work describes an object oriented software, to be portable among different types of computer platforms, able to perform the simulation of different components of Ethernet local and long distance area networks by using the TCP/IP protocol. It is also able to detect problems in projects and operation of communication networks through the separate or joint analysis of these elements. The functions of the system are as follows: (a) analysis of elements from different layers and protocols of the simulated network (reference to OSI model); (b) analysis and efficiency measurement (quality of transmission, transfer rate, error rate) of the information transmitted on the network; (c) network performance evaluation and link capability analysis; (d) analysis of error detection and further correction capability as well as analysis of network failure tolerance. The software works using mathematical models that represent elements of different layers (reference to OSI model) of the network to be simulated as well as the performance of the abovementioned joint elements.
