Abstract:
1. A method of data traffic control in a communication network, said method comprising: monitoring, using at least one network entity of the network, data traffic to determine if a failover operation has occurred in the network; and, if so, controlling, using the at least one network entity of the network, the data traffic in the network based on a differentiation between data congestion associated with data traffic volume in the network and data congestion associated with the failover operation; wherein: the data congestion associated with the data traffic volume in the network and the data congestion associated with the failover operation are controlled using first and second traffic control modes, respectively; the first mode is a general purpose congestion monitoring and recovery mode for controlling data congestion in the network without regard to any particular source of the data congestion; and the second mode is a failover congestion monitoring and recovery mode formulated to prevent instances of dropped communications on the network associated with the failover operation including instances that would be permitted by the first mode.
