Abstract: A method is provided in one example embodiment and includes identifying an Internet protocol (IP) address for a serving gateway; establishing a link between the serving gateway and a congestion notification element; monitoring packets in order to identify whether a differentiated services code point (DSCP) bit has been set in the packets; determining that a threshold associated with congestion in a network has been exceeded; and communicating a signal to the serving gateway associated with the congestion. The serving gateway can be configured to correlate the congestion with identifiers associated with end users operating in the network, where the serving gateway communicates a signal to a network element to reduce the congestion.

Abstract: To protect a multicast data stream for a multicast group, two P2MP pseudowires are established to deliver multicast data for the particular multicast group to an aggregation node. The two P2MP pseudowires are defined such that the pseudowires have no transport nodes in common other than the aggregation node. The aggregation node replicates data received via a primary pseudowire of the two P2MP pseudowires to subscribers of the multicast group. The aggregation node monitors the data from the primary pseudowire to detect failures in the data flow. When a failure is detected in the primary data stream, the aggregation node replicates data received via a secondary pseudowire of the two P2MP pseudowires for delivery to the multicast group subscribers.
