Abstract: 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.

Abstract: 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 (100). 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 (100). 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).
