- 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.

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.

Approximate study time: 6 hours
