    摘要： A payload switching architecture for LEO satellite networks minimizes processing and storage requirements of payloads for deployment as small primary or secondary payloads, payloads perform only forwarding functions. Forwarding rules are provisioned in the payloads enabling them to reroute in case of failures or congestion without intervention from a ground station. Configuration rules are provisioned in the payloads enabling them to dynamically establish and remove interplane crosslinks without intervention from a ground station. The central network operations center on the ground computes forwarding rules and configuration rules for payloads and uploads the rules to the payloads.

    摘要： Systems and methods for efficiently provisioning and assuring Quality of Service (QoS) between user networks communicating over a DiffServ-enabled network, with QoS management transparency to SIP user agents. The system comprises user networks communicating via a core network, each user network having a source and destination SIP user agent respectively, a SIP proxy server between the source SIP user agent and destination SIP user agent, a Bandwidth Manager to provision a pipe between the source user network and the destination user network, wherein the pipe has a specified bandwidth, and a QoS Agent for accepting and/or rejecting a SIP session based on availability of bandwidth in the pipe; wherein the SIP proxy server is configured to forward an incoming SIP request to the QoS Agent. The method comprises provisioning a pipe between the SIP user agents or their respective user networks, and allowing/rejecting incoming SIP sessions based on the available bandwidth in the pipe.

    摘要： In one aspect a method for correlating network events in a network comprises correlating the events relating to paths with events relating to links traversed by paths. In another aspect, the method includes correlating the events based on whether paths traversing the network share network resources, such as links. Preferably, the method is implemented in a network where paths traversing the network change dynamically in response to other network events and based on traffic engineering priorities.

    摘要： A system and method for determining an efficient assignment of information categories to multicast addresses is described. In one embodiment, the assignment takes into account the overlapping info cation needs of the subscriber nodes and the network bandwidth that will be consumed in the dissemination of each information category based on its size and the frequency of dissemination. In another embodiment, the assignment takes into consideration the additional constraint of a quality of service network having different prioritizations associated with the information categories.
