Transport of Next-Generation Data Services over SDH

Course Duration: 3 days

Course Code: PWL085

Course Description:

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.

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

Prerequisites:

It will be assumed that attendees will already have a knowledge of Next Generation Networks such as that obtained from courses in Multi Service Access.

Prerequisite courses:

Understanding MultiService Access and H.248

Understanding MultiService Access and SIP

Understanding IMS and TISPAN
