Field: Telecommunications (Electrical engineering)
Classification: CPC H | IPC H

Claim 0:
1. A communication network comprising:
a plurality of specialized nodes; and
a switch fabric comprising a plurality of data packet switching nodes, each of the specialized nodes being locally connected to the switch fabric at a corresponding port of one of the data packet switching nodes, wherein:
one of the specialized nodes is capable of operating as an ingress node to convert one or more incoming data flows into a packetized, time-division multiplexed (TDM) data flow;
the switch fabric is configurable to route the packetized, TDM data flow via a same selected path through the switch fabric in a contention-free manner to another of the specialized nodes; and
the another of the specialized nodes is capable of operating as an egress node of the packetized, TDM data flow received from the switch fabric by performing jitter compensation to convert the received packetized, TDM data flow into one or more outgoing data flows, wherein the communication network is configured to route at least one selected incoming data flow of the one or more incoming data flows through the switch fabric with a jitter level that is guaranteed to be maintained within a specified jitter range.
