Advanced IP networks course

Multimedia services such as Voice over IP (VoIP) are best provided if the IP network has been upgraded to offer users a differentiated quality of service (QofS). This course first describes the techniques that are used to offer a differentiated QofS over an IP network and then describes the role of the various protocols involved in providing a Voice over IP (VoIP) service.

Prerequisites:

An understanding of the operation and use of the Internet protocols including route discovery, and voice compression techniques. It is recommended that TransNet course F - "IP networks" and StarTel course B - "Principles of voice encoding and transmission" - are studied before attempting this course.

Course objectives :

At the end of this e-learning course a trainee will be able to:

describe the role and operation of the Resource Reservation Protocol (RSVP) in reserving network resources for a traffic stream.

describe how the DiffServ protocol allows a particular class of service to be provided for a traffic stream.

describe the facilities, operation and components of an IP network using Multiple Protocol Label Switching (MPLS).

describe how traffic engineering considerations can be taken into account when provisioning MPLS label switched paths.

describe the transport of encoded voice samples over an IP network with reference to the Real-time Transport Protocol (RTP) and the RTP Control Protocol (RTCP).

describe the role of, and relationship between, the various protocols used by a Voice over IP (VoIP) system including SIP, SDP, RTP and RSVP.
