Hands-On IP Multicasting for Multimedia Distribution Networks

Course Description

This Hands-On course provides an in-depth look how IP multicasting works, its advantages and limitations and how it can be deployed to provide effective services over a Next Generation 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

In order 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.

Equipment Requirements
(This apply's to our hands-on courses only)

BTS always provides equipment to have a very successful Hands-On course. BTS also encourages all attendees to bring their own equipment to the course. This will provide attendees the opportunity to incorporate their own gear into the labs and gain valuable training using their specific equipment.
