DISCOVERING IP MULTICAST GROUP MEMBERSHIPS IN SOFTWARE DEFINED NETWORKS
摘要
Provided is a method of discovering multicast group memberships in a software defined network. A multicast group membership query message is sent only to a selected network device in the network. The network device forwards the multicast group membership query message to a host computer system connected to the network device and recognizes a multicast group membership request from the host computer system in response to the group membership query message.
