A capability for providing policy enforcement in a topology abstraction system is presented. The capability for providing policy enforcement in a topology abstraction system may support use of topology abstraction policies to control abstraction of topology information of a topology (e.g., a network topology of a communication network or any other suitable type of topology). The capability for providing policy enforcement in a topology abstraction system providing an abstract representation of a topology may support use of topology abstraction policies to control selection (or acceptance) of topology elements for inclusion within the abstract representation of a topology and filtering (or rejection) of topology elements from being included within the abstract representation of a topology. The capability for providing policy enforcement in a topology abstraction system providing an abstract representation of a topology may support use of topology abstraction policies to control clustering of topology elements selected for inclusion within the abstract representation of the topology.

Policy enforcement in a topology abstraction system

The invention concerns a method of providing an MMoIP communication service, and a MMoIP system to execute the said method. One or more MMoIP packet streams (T1(x)) are transmitted via a connection (C(T1,T2)) established between a first and second endpoint (T1, T2) of an IP communication network (). The one or more MMoIP packet streams (T1(x)) comprise MMoIP payload data and/or control data. Control data directed to a processor (P) is inserted in at least one MMoIP packet stream (T1(x)) of the one or more MMoIP packet streams (T1(x)) at the first endpoint (T1) and the second endpoint (T2). The one or more MMoIP packet streams (T1(x)) are transmitted via an MMoIP switch (S) of the IP communication network (). The MMoIP switch (S) monitors the one or more MMoIP packet streams (T1(x)). The MMoIP switch (S) detects the control data directed to the processor (P). The MMoIP switch (S) forwards the detected control data to the processor (P).

Method of providing an MMoIP communication service

Various exemplary embodiments relate to a method of determining a cost for a routing path in a network. The method includes: receiving a first metric for a plurality of links in a network, the first metric being a routing metric used to determine routing in the network; determining a routing path including a subset of the links based on the first metric, the routing path having an initial cost based on the first metric; receiving second metric information including a second metric that is different from the first metric; and calculating a corrected cost for the routing path based on the second metric.

Multi-source correlation of network topology metrics

One or more MMoIP packet streams are transmitted via a connection established between a first and second endpoint of an IP communication network. The one or more MMoIP packet streams include MMoIP payload data and/or control data. Control data directed to a processor is inserted in at least one MMoIP packet stream of the one or more MMoIP packet streams at the first endpoint and/or the second endpoint. The one or more MMoIP packet streams are transmitted via an MMoIP switch of the IP communication network. The MMoIP switch monitors the one or more MMoIP packet streams. The MMoIP switch detects the control data directed to the processor. The MMoIP switch forwards the detected control data to the processor.
