IP Networks

This online course describes the principles and operation of networks that employ the Internet Protocol (IP). 

IP Networks

Course Description

The Internet has revolutionised modern communications. With the convergence of voice, video and data services, the trend is for telecommunications providers to use the same technologies that underpin the Internet to provide all telecoms services. This course by PTT introduces the principles of operation of networks that employ the suite of protocols that were originally designed for the Internet but are now widely used in wide area networks generally. The course begins by describing the Internet infrastructure and the role of the organisations involved in the running of the Internet. Commercial aspects of the interconnection of the networks that make up the Internet are also discussed. The course then describes the role and operation of the various protocols that are employed on the Internet including IP, TCP, UDP and HTTP. The... Read More »

The Internet has revolutionised modern communications. With the convergence of voice, video and data services, the trend is for telecommunications providers to use the same technologies that underpin the Internet to provide all telecoms services.

This course by PTT introduces the principles of operation of networks that employ the suite of protocols that were originally designed for the Internet but are now widely used in wide area networks generally. The course begins by describing the Internet infrastructure and the role of the organisations involved in the running of the Internet. Commercial aspects of the interconnection of the networks that make up the Internet are also discussed. The course then describes the role and operation of the various protocols that are employed on the Internet including IP, TCP, UDP and HTTP. The concept, advantages and administration of IP addresses are described. The translation between web links (URLs) and IP addresses is also explained. The way in which traffic is routed over the Internet is explained with reference to the operation of routers and route discovery protocols.
