Internet Protocols

The Internet in its current form crucially relies on various communication protocols, which are distributed procedures and algorithms governing how different computers in the Internet can reach each other and exchange messages and data reliably. Two core classes of protocols are routing protocols, which help to find paths between arbitrary computers, and transport protocols, which achieve reliable data transfer over an inherently unreliable network. In this course we develop an advanced understanding of the operation, performance and scalability of selected protocols in these two classes (for example the OSPF routing protocol, and the TCP and other transport protocols). Students will implement and simulate selected aspects of such protocols and evaluate their performance.
