Abstract
Techniques for efficiently initiating multicast data communications. Upon determining to initiate multicast network communications, embodiments determine that a first multicast group of a plurality of multicast groups is currently active. An Internet Group Management Protocol (IGMP) Join network message for a second multicast group that is currently inactive is transmitted. Upon determining that the first multicast group is currently inactive, an IGMP Join network message is transmitted for the first multicast group of the plurality of multicast groups.
