Abstract: Methods, systems, and computer program products for setting congestion levels for a plurality of routes to a common destination are disclosed. According to one method, a transfer controlled (TFC) message concerning a destination is received at a signaling message routing node that maintains a plurality of routes to a common destination. The signaling message routing node tests a congestion level of each of the routes to the destination. The signaling message routing node sets congestion levels for the routes based on results of the testing.

Abstract: Methods, systems, and computer program products are provided for taking a high-speed signaling link out of service from a proving state of an initial alignment procedure in response to a flag delimitation error. According to one aspect, the method includes initializing an initial alignment procedure for validating the ability of a high-speed signaling link to carry signal units and transitioning to a proving state. While in the proving state, the method includes detecting a flag delimitation error and in response to detecting the flag delimitation error, starting a timer. The method further includes taking the link out of service based on the timer.

Abstract: Methods, systems, and computer program products for thermal management of a processor associated with a network interface are disclosed. According to one method, message traffic is sent and received using a first processor associated with a first network interface. A temperature associated with the first processor is determined. Message traffic is switched from the first processor to a second processor in response to the temperature associated with the first processor having a predetermined relationship with respect to a threshold value. The threshold value can be less than a thermal shutdown level of the first processor.

Abstract: A signaling network routing node, such as a signaling system 7 (SS7)/Internet protocol (IP) gateway, is adapted to perform global title translation (GTT) or other processing on received signaling messages and route the signaling messages to a member of a load sharing group using a threshold-based weighted load sharing algorithm. In the event that one of the signaling destinations in the load sharing group becomes unavailable, signaling message traffic is redistributed evenly among the remaining available members of the load sharing group in a manner such that a maximum load sharing weight threshold value associated with each group member is not exceeded.
