Patent number: 9544080Abstract: The invention includes, among other things, a system for passing TDM traffic through a packet switch. In one embodiment, the system includes a packet switch that has a plurality of data ports and is capable of routing FSDU packets between the plurality of data ports. A TDM encapsulation circuit process a TDM data flow that is incoming to the switch. A circuit demultiplexer processes the incoming data flow to buffer data associated with different TDM circuits into different buffer locations. A timer monitors the amount of time available to fill the FSDU, and when the time period reaches the frame boundary, an FSDU generator generates an FSDU that is filled with data associated with the TDM circuits. Header information is added for allowing the packet switch to route the generated FSDU to a port associated with the respective TDM circuit.Type: GrantFiled: June 20, 2014Date of Patent: January 10, 2017Assignee: Genband US LLCInventors: Daniel W.

Patent number: 7719962Abstract: A method to increase the capacity efficiency of span-restorable mesh networking on sparse facility graphs. The new approach views the network as a “meta-mesh of chain sub-networks”. This makes the prospect of WDM mesh networking more economically viable than with previous mesh-based design where the average nodal degree is low. The meta-mesh graph is a homeomorphism of the complete network in which edges are either direct spans or chains of degree-2 nodes. The main advantage is that loop-back type spare capacity is provided only for the working demands that originate or terminate in a chain, not for the entire flow that crosses chains. The latter “express” flows are entirely mesh-protected within the meta-mesh graph which is of higher average degree and hence efficiency for mesh restoration, than the network as a whole. Nodal equipment savings also arise from the grooming of express lightpaths onto the logical chain-bypass span. Only the meta-mesh nodes need optical cross-connect functionality.Type: GrantFiled: October 19, 2001Date of Patent: May 18, 2010Assignee: Telecommunications Research LaboratoriesInventors: Wayne D.

Patent number: 7545801Abstract: Systems for in-band control that establish relationships between incoming data and one or more destinations to which the data is to be transmitted. In the in-band control embodiments described herein, a connection is established between two ends of a circuit by provisioning at one end of the circuit. A circuit connection table is kept at both ends of the circuit. This table contains the new and existing circuit connection information. A software process writes to the connection table at the local end of the circuit with the address information of the remote end of the circuit. The circuit connection information is to be periodically sent to the remote end to establish or tear down new connections.Type: GrantFiled: December 1, 2003Date of Patent: June 9, 2009Assignee: Cedar Point Communications, Inc.Inventors: Paul Miller, Jr., Daniel W.
