    摘要： A method of generating an annotated network topology of a network is described. The method includes; deriving a network topology by performing a route tracing utility between each pair of endpoints to determine the route taken by packets; initially annotating each network path with an initial value; determining the available bandwidth of a path connecting a pair of endpoints by performing Transfer Control Protocol (TCP) flows between the pair of endpoints; identifying a bottleneck link in the network path, and annotating all edges to generate an annotated network topology wherein available bandwidth annotation of links inside the network is determined using end-to-end network measurements.

    摘要： Managing application performance on a network. A network graph is generated from a set of application endpoints on the network. The network graph is annotated by associating one or more of the application endpoints with at least one of a corresponding latency annotation or a corresponding available bandwidth annotation. An end to end plan is formulated from the annotated network graph, wherein the plan maps one or more application requirements onto the plurality of paths in accordance with one or more end to end control adjustments including at least one of a server selection adjustment, an internet service provider (ISP) selector, or an overlay routing adjustment.

    摘要： Systems and methods are disclosed for differentiated handling of VoIP call control messages according to their importance and functionality, thus providing to VoIP infrastructures a level of robust call control similar to that in PSTN networks. SIP messages are classified by their type or content, and resources of a VoIP call control server are allocated to the SIP messages according to a policy. The scheme also provides overload protection and prioritized handling of certain kinds of requests in VoIP call control servers.
