|20110069610||HIGH CAPACITY RING COMMUNICATION NETWORK - A method for communication includes configuring a plurality of ring nodes to communicate over a communication network that includes two or more overlapping communication rings, each ring including two unidirectional ringlets in mutually-opposite directions. A data packet including one or more header fields is accepted at an ingress ring node. An egress ring node to which the data packet is to be forwarded by the ingress ring node is determined. A subset of the rings including one or more common rings that are connected to both the ingress and egress ring nodes is identified. A ringlet of a ring among the one or more common rings is selected responsively to a respective value of at least one of the header fields of the packet. The data packet is forwarded from the ingress ring node to the egress ring node over the selected ringlet.||03-24-2011|
|20100202452||HIGH-SPEED PROCESSING OF MULTICAST CONTENT REQUESTS - A method for communication includes operating a network element, which includes multiple ports and multiple interconnected processing units, such that each processing unit is assigned to process packets that are communicated over a respective set of one or more of the ports. Each processing unit stores a respective list, which indicates one or more multicast packet streams that are permitted for forwarding by the network element, and further indicates a respective subset of the ports over which each of the multicast packet streams is permitted for forwarding.||08-12-2010|
|20100172242||RING NETWORK AGGREGATE RATES - A functionality and method for determining aggregate data transit bandwidth requirements for the nodes of an Ethernet ring network for traffic management and to improve the operation, efficiency, and Quality of Service. An aggregate bandwidth database is produced, based on a priori knowledge of the ring network, including topology, path utilization, bandwidth sharing, and failure protection scenarios. Aggregate bandwidth requirements are determined independent of the actual real-time data traffic rates, and without requiring any actual real-time data traffic rate information. Aggregate bandwidth is automatically determined upon configuration or reconfiguration of the ring network.||07-08-2010|
|20100135297||UNICAST STREAMING OF MULTICAST CONTENT - A method for communication includes receiving an Internet Protocol Multicast (IPMC) packet for delivery to multiple subscribing hosts. The IPMC packet is encapsulated in a plurality of unicast frames that are respectively addressed to the subscribing hosts for transmission via a Layer 2 network to the subscribing hosts.||06-03-2010|
|20100110906||EFFICIENT FULL MESH LOAD TESTING OF NETWORK ELEMENTS - A method for testing a network element that includes multiple ports includes assigning one or more of the ports to serve as input and output test ports. One or more of the ports other than the test ports are terminated with respective loopback connections. The network element is configured to forward packets entering the network element at the input test port, so as to cause the packets to be distributed among the terminated ports and to exit the network element, after re-entering the network element at one or more of the terminated ports, at the output test port.||05-06-2010|
|20090175278||EFFICIENT TRANSPORT OF TDM SERVICES OVER PACKET NETWORKS - A method for data communications includes receiving a time-division-multiplexed (TDM) input signal carrying a payload comprising data and determining whether the data comprise synchronous or non-synchronous data. A first encapsulation scheme is selected if the data comprise synchronous data, and a second encapsulation scheme is selected if the data comprise non-synchronous data. The data are encapsulated for transmission over a packet-switched network in accordance with the selected encapsulation scheme.||07-09-2009|
|20080285442||Vpls Remote Failure Indication - A method for communication includes provisioning different first and second instances of a multipoint-to-multipoint (MP-MP) communication service over respective first and second alternative sets of links (||11-20-2008|
|20080222447||PREVENTION OF FRAME DUPLICATION IN INTERCONNECTED RING NETWORKS - A method for communication includes, in a communication network that includes multiple ring nodes arranged in at least first and second ring networks that are connected by two or more of the ring nodes serving as interconnect nodes, accepting at the two or more interconnect nodes respective copies of a data packet, which is sent from a source user node connected to the first ring network.||09-11-2008|
