Multicasting

The VAST2 supports multicasting of live streams from server to clients. If multiple VAST2 clients
demand live videos from the same camera, multicasting cna help save considerable system resources.

Multicasting should be enabled on a VAST server and also on individual cameras.

There are prerequisites:
1. Both the VAST2 server and clients have to be revision 2.7 or above. If any of them is running revisions

before 2.7, client connections will crash.

2. Multicasting is not supported under the following conditions:

* A CMS local client can only access the live stream from the cameras managed by the CMS server

using unicast connections.

* If the need arises for access to cameras managed by VAST sub-stations, the multicasting

configuration should take place on the sub-stations instead of on the CMS server.
