Foundations of Internet


Become familiar with general characteristics and functionality of current telecommunications networks and their possible evolution. Learn how a generic network works. Become familiar with layered communication architectures, transfer modes, LANs, interworking systems and the protocol architecture of the Internet. Know the key protocols of the Internet. Know basic analytical and simulation tools to evaluate the performance of a network. Be able to understand the literature and to quantitatively compare different solutions.
