Patent number: 8201206Abstract: In an IPTV network, cache memory assigned to each DSLAM, Central Office (CO) or Intermediate Office (IO) can be determined by defining a network cost function having cache memory per DSLAM, cache memory per CO and cache memory per IO as decision variables. The network cost function can be minimized to determine the optimal cache memory size for the network. The network cost function can be subject to boundary constraints that the cache memory is between zero and a maximum cache memory size for each network node type, allowing the network cost function to be solved as a 3-ary tree.Type: GrantFiled: July 31, 2009Date of Patent: June 12, 2012Assignee: Alcatel LucentInventors: Lev B Sofman, Bill Krogfoss

Patent number: 7747761Abstract: A system and method for establishing a SIP session between calling and called end-points. A SIP server receives a SIP INVITE request for establishing the SIP session. The SIP INVITE request includes standard routing information in its header.

Patent number: 7706519Abstract: An assembly, and an associated method, by which to place a telephonic station in virtual residency in a telephonic network. The virtually-resident telephonic station is coupled to a packet data network, such as the Internet backbone. The virtually-resident telephonic station has packet network address determined by the location of its connection to the packet data network. An index, formed by an indexer, is maintained at a proxy server embodied at the packet data network. When a call is placed by a calling station for connection with the virtually-resident telephonic station, the call is routed to the packet data network, and the index is accessed to ascertain the address of the virtually-resident telephonic station. When the address is ascertained, the call is routed to the virtually-resident telephonic station, and the call connection is completed.Type: GrantFiled: July 2, 2003Date of Patent: April 27, 2010Assignee: Alcatel LucentInventors: Ronald F.

Patent number: 7639674Abstract: A data communications switch for dynamically distributing packet processing operations between an ingress and egress processor for load balancing is disclosed. The invention in the preferred embodiment features a switching device including a plurality of switching modules, each of the switching modules including a packet classifier for identifying one or more packet processing operations to be applied to an ingress packet and a controller adapted to allocate each of the identified one or more packet processing operations between a first set of packet processing operations and a second set of packet processing operations, execute the first set of packet processing operations at the ingress processor at which the packet was received, and transmit instructions to the egress processor to execute the second set of packet processing operations. The egress processor then executes the second set of packet processing operations, after which the packet may be transmitted toward its destination node.Type: GrantFiled: October 25, 2004Date of Patent: December 29, 2009Assignee: Alcatel LucentInventors: Chiang Yeh, Dennis Weaver

Patent number: 7631096Abstract: A method and apparatus for provisioning bandwidth among a plurality of queues in a switching device are disclosed. The bandwidth provisioning employs a QoS label with a timestamp to determine the queue delay associated with the transmission of the packet from an ingress switching device, e.g. ingress blade, to an egress switching device, e.g. egress blade. The QoS label is applied on the ingress blade and removed and read on the egress blade. Using the timestamp, the switch can identify congested priority queues at the ingress blade and selectively enable fragmentation for purposes of preventing particular packets and or particular flows from consuming disproportionately large system resources including bandwidth necessary to communicate packets through the switch fabric. Some QoS labels may further include instruction sets and a fragmentation identifiers used by the egress blade to reassemble the packet fragments.Type: GrantFiled: October 14, 2003Date of Patent: December 8, 2009Assignee: Alcatel LucentInventors: Chiang Yeh, Dennis Weaver

Patent number: 7621162Abstract: A method of multiplexing a plurality of data flows into a single output using hierarchical gating operations instead of queues is disclosed. In the preferred embodiment, the hierarchical multiplexing method comprises sequentially processing a packet at each of a plurality of hierarchical levels by characterizing the flow at each hierarchical level and either passing or discarding the packet. The decision whether to pass or discard a packet is generally made for each packet at one or more hierarchical levels based on traffic parameters and the state of the system such as congestion. In the preferred embodiment, a Three Color Marker algorithm is used to characterize the flow and mark packets subjecting to the discard decision. The invention may be used by a router or multi-layer switch to process multiple data flows in a hierarchical fashion without hierarchical queues, thereby reducing processing and memory requirements.Type: GrantFiled: December 30, 2003Date of Patent: November 24, 2009Assignee: Alcatel LucentInventor: Alan Keith Bartky
