Overview

Next generation networks will be deployed with high speed, high quality broadband DSL access capable of using flexible coding techniques. Multi-Service Access Nodes will carry services to Intelligent Nodes closer to the core where services will be located and then on to the network core using MPLS. The access is likely eventually to evolve into an all Ethernet service and the range of services carriers must deliver will need to be carried over existing SDH services.  This course aims to provide an understanding of how these new services can be carried over SDH and how SDH is being enhanced to provide new capabilities to deliver the services in a flexible efficient manner.

Objectives

When you have completed this course you will be able to:

  • Describe how access services are evolving
  • Compare existing SDH transports with new evolving Next Generation SDH
  • MAP Access services to SDH with GFP
  • Employ Virtual Containers in the Transport
  • Utilize for efficient service deployment
  • Enhance switching technologies to interface to GMPLS core services
  • Deploy mechanisms to deliver End to End QoS for applications.
