Abstract:
1. A method for dynamically load sharing signaling messages among mated signaling destinations in response to changes in network operating conditions, the method comprising: (a) defining a group of signaling destinations as a load sharing (LS) group, wherein defining a group of signaling destinations as a load sharing group includes provisioning a data structure such that post-global-title translated (post-GTT) signaling message traffic is assigned to a load sharing group based on the post-GTT destination point code in each message; (b) assigning each member of the LS group a nominal load sharing weight (LSW) and a maximum load sharing weight threshold (MWT); (c) in response to a LS group member becoming unavailable to receive signaling message traffic, distributing the LSW associated with the unavailable member among the remaining available members in a manner such that the MWT thresholds associated with each of the remaining available members are not exceeded, wherein distributing the LSW among the remaining available members includes dynamically altering relative load sharing weights assigned to entries in the data structure corresponding to the remaining unavailable members of the load sharing group; and (d) load sharing post-GTT signaling message traffic destined for a member of the LS group in accordance with each available group member's dynamically altered LSW.
