摘要
A signaling network routing node, such as a signaling system 7 (SS7)/ Internet Protocol (IP) gateway (300), is adapted to perform global title translation (GTT) or other processing (312) on received signaling messages and route the signaling messages to a member o a load sharing group using a threshold-based weighted load sharing algorithm (316). 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 member of the load sharing group in a manner such that the maximum load sharing weight threshold value associated with each group member i not exceeded. If a load sharing group member becomes unavailable, and the resulting recalculated load sharing weights of the remaining available members sum to less than 100%, then load sharing weights for the group are normalized, and a maximum message rate capacity threshold associated with each group member is used to determine whether the discarding of messages is required.
