Abstract: Methods, systems, and computer program products for multicast compression and pacing are disclosed. In one method, messages relating to events that affect or require use of a database maintained by multiple processing modules in a distributed processing system are received. The messages are buffered and placed in a third message in a manner that preserves time ordering of the messages. The packed message is then multicast to the processing modules. Each processing module processes messages that are addressed to it. A method for pacing multicast messages destined for the processing modules is also provided.

Abstract: Methods, systems, and computer program products for reducing the likelihood of signaling link congestion on a failing or recovering signaling linkset are disclosed. According to one aspect, a method for reducing or eliminating congestion on a recovered link in a previously failed linkset due to the routing of post-global title (GT) translated signaling message traffic is disclosed. When the first link in a previously failed linkset becomes available, routes associated with the recovering linkset are marked as restricted. GT translated messages are directed to the lowest cost route that is marked as allowed. If no routes are marked as allowed, messages are directed to the lowest cost route that is marked as restricted. When a predetermined number or percentage of the links in a linkset become available, routes associated with the recovering linkset are marked as allowed.

Abstract: The subject matter described herein includes methods, systems, and computer program products for selective network management in a network having multiple active routes to a common destination that are keyed by different combinations of parameters. According to one aspect, the subject matter described herein includes a method for controlling distribution of network management messages concerning the status of a signaling link by provisioning a routing node with a primary route to a destination and at least one exception route to the destination wherein the primary route and the exception route are keyed by different combinations of signaling message parameters.

Abstract: Methods, systems, and computer program products for individually identifying and disabling circular routes from active routes to a common destination are disclosed. According to one method, multiple active routes are maintained to a common destination. Congestion is detected on a signaling link associated with at least one of the routes. In response to detecting the congestion, at least one of the routes is tested for circularity. One of the routes is identified as circular based on the testing. In response to identifying the route as circular, the route is disabled and use of the remaining active routes to the destination is continued.

Abstract: Methods and systems for providing enhanced network security for network management messages and subsystem management messages are disclosed. A network security function receives a network or subsystem management message from a first location in a network. The network security function determines whether one or more predetermined parameters in the network management message are not associated with the originating location. In response to determining that are not associated with the originating location, a network security action, such as discarding the message and/or notifying a network operator, is performed.

Abstract: Methods and systems for distributing signaling messages among multiple processors for stateful processing and/or sequenced processing of the messages on a per sequence basis are disclosed. A signaling message is received and it is determined whether the signaling message requires stateful and/or sequenced processing. If the signaling message requires stateful and/or sequenced processing, a sequence identifier is computed for the signaling message. The sequence identifier is unique on a per sequence basis. The sequence identifier is then used to distribute the signaling message to an application processor for stateful and/or sequenced processing.
