Course Description:
The real time transfer of information from source to many receivers is increasingly a requirement of modern networks. While it is possible to transfer information with simple client server techniques developed within the Internet Protocol Suite, transfer using this unicasting does not scale well to large communities.
Multicasting provides a means of distributing information to multiple receivers at the same moment over a tree of paths through routed networks.
In its simplest form it can be used for the distribution of streams of multimedia over a private infrastructure delivering different channels each as a different multicast group address. In the corporate environment it might be carried over VPNs configured over MPLS infrastructures where the network provision may be separated from the sources and receivers. In such environments the configuration and troubleshooting of stream transmission becomes more challenging.
This course will provide a sound coverage of Multicast protocols and addressing. This will include Protocol Independent Multicast (PIM) and Internet Group Management Protocol (IGMP) versions 2 and 3. Key addressing and multicast routing will be considered for both within Autonomous Systems and Between Autonomous Systems.
The scaling implications of both source tree and shared tree techniques will be considered and the mechanisms for advertising, requesting and pruning distributed streams will be considered.
The mechanisms available for monitoring and troubleshooting stream distributions on Cisco platforms will be considered.
