Signal processing apparatus and signal processing method thereof for implementing a broadcast or a multicast communication

摘要

A communication system includes: a control apparatus that sets broadcast domains or multicast domains respectively for virtual networks configured in a physical network including a forwarding node(s), and sets, in the forwarding node(s), broadcast or multicast control information, associating a packet forwarding destination and a match condition including an identifier for identifying one of the broadcast domains or multicast domains; and the forwarding node(s) that performs a broadcast or multicast using the broadcast or multicast control information.

主权项

1. A control apparatus, comprising:
a memory storing virtual node information concerning a virtual node, the virtual node information including a virtual network identifier; and a processor configured to execute program instructions to:
identify, based on the virtual node information, a network domain identifier corresponding to one of a broadcast domain and multicast domain;identify, based on the network domain identifier, a packet processing instruction for processing a packet according to the virtual network identifier and the network domain identifier; andsend the packet processing instruction to an edge switch apparatus corresponding to the virtual node.
