Abstract:
1. A method for dynamic distributed link table consistency management, the method comprising: (a) maintaining, on a plurality of different link interface modules for routing signaling messages in a distributed signaling message routing system, a plurality of signaling link tables having the same signaling link entries, wherein each signaling link table is used by one of the link interface modules to route signaling messages from inbound to outbound signaling links; (b) sending a signaling link table data error detecting code request from a first link interface module having a first signaling link table to a second link interface module having a second link interface table; (c) at the second link interface module, in response to the request, computing a data error detecting code for the second signaling link table and sending the data error detecting code to the first link interface module; (d) at the first link interface module, computing a data error detecting code for the first signaling link interface table and comparing the data error detecting code computed for the first signaling link table to the data error detecting code received from the second link interface module; (e) in response to detecting a match between the data error detecting codes, repeating steps (b)-(d) for the next link interface module in the system; and (f) in response to failing to detect a match between the data error detecting codes, taking corrective action.
