A method for multi-layered distributed GTP-processing for communication between user devices () via a communication network (), the network comprises clusters () each cluster () including gateways () and a loadbalancer (), and a runtime database () storing load information of the gateways and a subscriber data-base () storing information on user preferences. The method comprises the loadbalancer (), after receipt of a connection request, to choose the least loaded gateway (), identifying if the cluster () is the preferred cluster of the user, and establishing, if the cluster is the preferred cluster, a connection between the user devices () via the gateway () and in accordance with the user preferences or else, transmitting the connection request to the loadbalancer () of the preferred cluster (), the loadbalancer identifying the least loaded gateway () in that cluster and establishing via the gateway () a connection between user devices by sending a response message in accordance with the user preferences to the first gateway in the first cluster.

Methods, systems, and computer readable media for communicating media server capabilities and status information between a plurality of media servers and a media resource broker are disclosed. According to one method, messages are received at a media resource broker from a plurality of media servers, where the messages include information indicating capabilities and status of the media servers. The information regarding the capabilities and status of the media servers is cached at the media resource broker, which receives call setup requests and, in response, selects a media server from the plurality of media servers based on the cached media server capabilities and status information.

Methods, systems, and computer readable media for verifying the identity of a SIP user seeking to establish a session are disclosed. Methods for verifying the identity of a SIP user seeking to establish a session described herein may be performed at a computing platform that includes a SIP user agent. According to one method, an INVITE message for establishing a session is received, where the INVITE message includes sender identification information and dialog identification information. In response to receiving the INVITE message, a subscription request including the dialog identification information is sent to a second computing platform that includes a user agent identified by the sender identification information in the INVITE message. A response to the subscription request is received and, based on the response to the subscription request, it is determined whether the identity of the sender of the INVITE message can be verified.

A data flow system, where a sourcetransmits a reservation packet to an ingress element. The ingress elementpolices incoming message traffic and collects data flow information. Quality of service differentiation is realized by marking data packets of different data flows. The ingress elementregisters the reservation packet and forwards the request to a core router. The core routerevaluates the service level required, and available resources. Based on this evaluation the core routerwill reject, accept, or modify the received message, indicate the price for the requested level of service, and forward the reservation packet. The process is repeated until the reservation packet reaches the destination, which sends a feedback message to the sourceindicating the result of the reservation packet. After establishing a reservation, sourcetransmits periodic control messages and collects information regarding resource availability, and the flow path.
