This course deals with the study of computer networks, including the OSI reference model, services and its architecture, as well as the TCP/IP model. The study includes the stratified structure of each model, LAN technologies, LAN architecture, LAN standards and systems, as well as connectivity devices. It also provides an explanation of peer-to-peer networks, which are the main alternative to client-server networks when network size increases, data search protocols, storage methods and download mechanisms, problems that you may encounter and ways to solve them, file sharing applications such as Gnutella and Napstor and file transfer systems such as Bittorrent versions. Its most important working mechanisms such as file segmentation and parallel loading. In addition to studying routing algorithms (link state and ray distance), as well as IP routing protocols such as: RIP, RIPv2, OSPF, IGRP (Cisco), EIGRP (Cisco), IS-IS and BGP, where the characteristics of each protocol and the messages used within it and its mechanism of work are studied. Its applications, goals and requirements of network design.
