Multicast protocol types

WebSphere Message Broker supports two different types of multicast protocol:

PTL provides compatibility with WebSphere Business Integration Message Broker Version 5.0, where it is the only multicast protocol that is supported. For new multicast deployments, use one of the two PGM multicast protocols.

The broker supports two implementations of the PGM multicast protocol, PGM/IP and PGM UDP encapsulated. The complexity of your network topology affects which option you choose:
Important: To use PGM/IP, both the broker and the client applications must run with superuser authority. Because of the security risks that are associated with running with superuser authority, do not run any other work on the broker.
