20130100854 | VPLS OVER MULTI-CHASSIS TRUNK - One embodiment of the present invention provides a switch. The switch includes a link aggregation database, an arbitration module, a packet processor, and a logical connection management module. The link aggregation database stores information regarding a plurality of switches participating in a multi-chassis trunk. The plurality of switches includes the switch as well. The arbitration module selects a switch of the plurality of switches as an active switch based on the information in the link aggregation database. The packet processor constructs a packet for a remote switch forwardable via a logical connection. The logical connection management module operates in conjunction with the packet processor and constructs a message containing instructions for creating a second logical connection to a second switch of the plurality of switches. | 04-25-2013 |
20130124707 | SYSTEM AND METHOD FOR FLOW MANAGEMENT IN SOFTWARE-DEFINED NETWORKS - One embodiment of the present invention provides a system for facilitating flow definition management in a switch. During operation, the system identifies a generic flow definition which specifies a flow that is not specific to any input port of a switch. The system further stores in a flow lookup data structure one or more port-specific flow rules based on the generic flow definition, wherein each port-specific flow rule corresponds to a respective port capable of processing data flows. | 05-16-2013 |
20130318243 | INTEGRATED HETEROGENEOUS SOFTWARE-DEFINED NETWORK - One embodiment of the present invention provides a switch in a software-defined network. The switch includes at least one port, a flow management module, and forwarding circuitry. The port is capable of receiving a frame belonging to a software-defined data flow and a frame belonging to a regular data flow. The flow management module logically partitions the port for the frame belonging to the software-defined data flow from the frame belonging to the regular data flow. The forwarding circuitry forwards the frame belonging to the software-defined data flow based on a flow definition in a local flow table. The flow definition indicates how the software-defined data flow is processed in a software-defined network. | 11-28-2013 |
20140269746 | LOAD BALANCING OF LOGICAL CONNECTIONS OVER MULTI-CHASSIS TRUNK - One embodiment of the present invention provides a switch. The switch includes a link aggregation database and a packet processor. The link aggregation database stores configuration information regarding a plurality of switches participating in a multi-chassis trunk. The plurality of switches includes the switch. The packet processor constructs a packet for a remote switch. This packet is forwardable via a logical connection. The packet includes a virtual circuit label associated with a second logical connection of a second switch. The plurality of switches includes the second switch as well. | 09-18-2014 |
