    摘要： A fast and efficient method for network re-optimization is described. In one embodiment, the technique uses an algorithm that requires limited aggregate information to continually monitor the network for re-optimization opportunities. The re-optimization of the present invention enables a network to accommodate more traffic without adding capacity. The re-optimization of the present invention is performed only when network efficiency benefits above a predetermined threshold may be obtained. In addition, a least-cost set of sessions is determined to perform the re-routing of the present invention to attain the desired network efficiency.

    摘要： A flow deflection capability is provided for deflecting data flows within a Software Defined Network (SDN) in order to provide security for the SDN. A flow forwarding rule is generated for a first network element of the SDN based on detection of a condition (e.g., TCAM utilization condition, CPU utilization condition, or the like) associated with the first network element. The flow forwarding rule is generated by a control element of the SDN or the first network element of the SDN. The flow forwarding rule is indicative that at least a portion of new flow requests received at the first network element are to be forwarded from the first network element to a second network element of the SDN. The flow forwarding rule may specify full flow deflection or selective flow deflection.

    摘要： A capability is provided for providing transparent cloud computing with a virtualized network infrastructure. A method for enabling use of a resource of a data center as an extension of a customer network includes receiving, at a forwarding element (FE), a packet intended for a virtual machine hosted at an edge domain of the data center, determining a VLAN ID of the VLAN for the customer network in the edge domain, updating the packet to include the VLAN ID of the VLAN for the customer network in the edge domain, and propagating the updated packet from the FE toward virtual machine. The edge domain supports a plurality of VLANs for a respective plurality of customer networks. The packet includes an identifier of the customer network and a MAC address of the virtual machine. The VLAN ID of the VLAN for the customer network in the edge domain is determined using the identifier of the customer network and the MAC address of the virtual machine. The FE may be associated with the edge domain at which the virtual machine is hosted, an edge domain of the data center that is different than the edge domain at which the virtual machine is hosted, or the customer network. Depending on the location of the FE at which the packet is received, additional processing may be provided as needed.

    摘要： The invention includes a method and apparatus for determining a coincidence count associated with a traffic flow in a network. The method includes receiving a first packet having a first flow identifier associated with one of the traffic flows, comparing the first flow identifier of the first packet to each of a plurality of other flow identifiers associated with a respective plurality of other packets, and determining a coincidence count associated with the first flow identifier based on the comparison of the first flow identifier to each of the plurality of other flow identifiers. The method for determining a coincidence count associated with one of a plurality of traffic flows may be extended for determining respective coincidence counts associated with a plurality of traffic flows. The determined coincidence counts may be used for determining at least one traffic flow statistic.
