Training Course Outline
Course Duration:
2 days
Training Course Description:
This course provides an understanding of how IP multicasting works,
its advantages and limitations and how it can be deployed to provide
effective services over a 21st Century converged network. It will
demonstrate examples of multimedia service configurations in the
class-room and identify practical problems and their solution. It will
provide a detailed understanding for implementers, designers, managers
and infrastructure engineers that need to plan, implement and use the
new generation of networks and services.
The next generation of telecommunications networks will deliver
broadband data and multimedia services to users. Integration with TV,
music and radio distribution will become a reality provided mechanisms
to provide multicast delivery are implemented. This technology allows
a broadcasting station to send a single stream of packets into the
network and have these delivered to the subscribing users. It provides
therefore a scalable solution to the problem of transmitting IP
Television and other services over next generation IP infrastructures
To make multicasting function effectively it is necessary to deploy
routers and switches capable of supporting the appropriate protocols
and to design and configure the network correctly. Core
infrastructure, distribution nodes, access devices and client devices
all must play their part in a working service.
When you have completed this course you will be able to:
- Describe the basic function of
Multicast IP
- Select the appropriate Sparse Mode
or Dense Mode options for deployment
- Compare the efficiency of routed
and MPLS switched options for QoS networks
- Implement appropriate addressing
mechanisms for streams
- Provide reliability by deploying
the re-routing with Protocol Independent Multicast
- Select programme streams using
Internet Group Management Protocol
- Engineer Traffic loading
- Carry real time multicast services
over Real Time Transport Protocol and Real Time Streaming Protocol
Prerequisites:
A solid understanding of IP and WAN technologies is
required.
