Abstract:

Methods, systems, and computer readable media for regulating pinhole preservation traffic generated or received by firewall or network address translator (NAT) session initiation protocol (SIP) user agent clients (UACs) are disclosed. One method includes, maintaining a list of contact information for a plurality of SIP UACs registering from behind at least one of a firewall and a NAT. The method further includes iterating through the list to generate SIP messages to the different UACs such that the SIP messages to the different UACs are spaced at substantially regular intervals with respect to each other, wherein the SIP messages to the different UACs trigger responses from the UACs such that the responses are spaced at substantially regular intervals with respect each other.

Abstract:

The subject matter described herein relates to methods, systems, and computer readable media for generating and using statelessly reversible representations of SIP information by SIP cluster entities. One method includes, at a first SIP cluster entity, receiving a first SIP message including SIP information. The method further includes generating a second SIP message including a statelessly reversible representation of the SIP information. The method further includes transmitting, to a SIP entity that is not a member of the cluster to which the first SIP entity belongs, the second SIP message with the statelessly reversible representation and information for reaching the cluster.

US Classification:

709203, 709223

Abstract:

Methods, systems, and computer readable media system for collecting and distributing session initiation protocol (SIP) event watcher entity subscription information in a communications network are disclosed. According to one aspect, a system includes one or more notifier servers for receiving subscription requests for SIP event information associated with a plurality of watched entities from a plurality of watcher entities. The system further includes a watcher information (WINFO) server for receiving, from the notifier servers, SIP event subscription information that includes, for each watcher entity, an association between the watcher entity to each of the watched entities in which a subscription for SIP event information was requested by the watcher entity, for storing the SIP event subscription information in the WINFO server, for receiving, from one of the watched entities, a request for watcher entity subscription information associated with the requesting watched entity from one of the watched entities, and for accessing the SIP event subscription information to locate the watcher entity subscription information associated with the requesting watched entity.

US Classification:

726 9, 709228, 726 22

Abstract:

Methods, systems, and computer readable media for media session policy compliance auditing and enforcement using a media relay and session initiation protocol (SIP) signaling are provided. One method includes at a SIP policy server, receiving SIP signaling from a user agent client to obtain a policy for media session and, in response, generating at least one media session correlation token. At least a portion of the SIP policy server is implemented in hardware. The media session correlation token and the media policy are communicated to the user agent client and to a media relay. Identification information for the media relay is also communicated to the user agent client. At least a portion of the media relay is implemented in hardware. At the media relay, the media session correlation token is received and used to correlate and store usage information for the media session and to monitor compliance with the media policy.

US Classification:

709239

Abstract:

Methods, systems, and computer readable media system for collecting and distributing session initiation protocol (SIP) event watcher entity subscription information in a communications network are disclosed. According to one aspect, the method includes receiving, at a first notifier server from a watcher entity client, a first subscription request for SIP event information associated with one or more watched entity clients. The method also includes receiving, at a watcher information (WINFO) entity, SIP event subscription information that includes an identifier indicating that the first notifier server serves the watcher entity client, storing the SIP event subscription information in the WINFO entity, detecting the unavailability of the first notifier server. The method further includes sending an instruction message, based on the identifier in the stored SIP event subscription information, to direct the watcher entity to generate a second subscription request associated for the SIP event information.

Abstract:

Methods, systems, and computer readable media for predicting imminent Diameter overload conditions using load information are disclosed. One embodiment of a system for implementing the subject matter described herein includes a first Diameter node including at least one network interface for receiving Diameter messages and a Diameter overload prediction unit. The Diameter overload prediction unit may be configured to extract load information from the Diameter messages, detect a traffic pattern using the extracted load information, predict at least one overload condition associated with one or more other Diameter nodes, and communicate an indication of the predicted overload condition to at least some of the other Diameter nodes before a time at which the overload condition is predicted to occur.
