Abstract
A network node includes a primary incoming interface, a secondary incoming interface and a data flow control unit. The primary incoming interface is operable to receive traffic associated with a particular source and multicast group. The secondary incoming interface is operable to serve as a backup interface if the primary incoming interface or a transmission path coupled to the primary incoming interface is inoperative. The data flow control unit is operable to determine whether the network node is part of a ring topology and if so, forward traffic received on the primary incoming interface associated with the source and multicast group to both a host which joined the multicast group and the secondary incoming interface and forward traffic received on the secondary incoming interface associated with the source and multicast group to the primary incoming interface.
