Assignee: NOKIA SOLUTIONS AND NETWORKS OY
Field: Telecommunications (Electrical engineering)
Classification: CPC H | IPC H

Claim 13:
14. A specialized node for a communication network comprising an ingress node, a switch fabric comprising a plurality of data packet switching nodes, and an egress node, wherein:
the ingress node is configured to convert one or more incoming flows into a single, packetized, time-division multiplexed (TDM) flow;
the switch fabric is configured to route the TDM flow via a fixed path through the switch fabric in a contention-free manner; and
the egress node is configured to perform jitter compensation to convert the TDM flow received from the switch fabric into one or more outgoing flows corresponding to the one or more incoming flows, wherein the specialized node comprises a memory connected to a processor that enables the specialized node to be configurable to be either the ingress node or the egress node, wherein the specialized node is one of the ingress node and the egress node, wherein the specialized node is configured to enable the communication network 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.
