TAH: Advanced IP networks
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.

What does this mean?
Target audience:
This course is designed for technicians and engineers involved in the design, commissioning and maintenance of networks using the Internet Protocol.
Course prerequisites:
You will get the most out of this course if you already have a basic understanding the principles of the Internet Protocol and routing. It is recommended that the PTT e-learning course "IP networks" is studied before attempting this "Advanced IP networks" course. The study of the PTT course "Interior IP routing" is also suggested.
Course objectives:
By the end of this course you will be able to:
- describe the role and operation of the Resource Reservation Protocol (RSVP) in reserving network resources for a traffic stream.
- explain that RSVP works in conjunction with conventional route discovery protocols such as OSPF.
- describe how the DiffServ protocol allows a particular class of service to be provided for a traffic stream.
- compare the admission control aspects of Diffserv and RSVP and describe they can be used in conjunction with each other.
- describe the facilities, operation and components of an IP network using Multiple Protocol Label Switching (MPLS).
- describe the role and operation of the Label Distribution Protocol (LDP) with reference to its relationship with routing protocols such as OSPF.
- 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.
