Subject: OmniStream™ Session Multicast and Port


A multicast address is a logical identifier for a group of hosts in a computer network that are available to process datagrams or frames intended to be multicast for a designated network service. Multicast addressing can be used in the link layer (Layer 2 in the OSI model), such as Ethernet multicast, and at the internet layer (Layer 3 for OSI) for Internet Protocol Version 4 (IPv4) multicast.

At the end of the multicast assignment click the “Save” button for your changes to take effect:
