    摘要： According to one embodiment, availability information describing virtual machines running on physical machines is accessed. The availability information associates each virtual machine with a physical resource used by the virtual machine. Use by the virtual machines is determined from the availability information. Availability of the physical resources is determined according to the use. Server load is balanced according to the availability of the physical resources. According to another embodiment, the following is performed until a load is accommodated: selecting a server having a load that is less than an expansion threshold; loading the server until the expansion threshold is reached; selecting a next server having a load that is less than a next expansion threshold; and loading the next server until the next expansion threshold is reached. Load of a low load server is determined to be below a contraction threshold, and the low load server is drained.

    摘要： At least one first frame of a first data flow can be received and passed to a general processor to inspect the at least one first frame. A flow acceleration request can be received including a set of conditions for accelerated processing, by a network processor, of a set of frames in the first data flow subsequent to the at least one first frame. At least one subsequent frame in the set of frames can be processed, using the network processor, in connection with forwarding of the subsequent frame to at least one remote network node, where processing of the subsequent frame is accelerated relative to processing of the at least one first frame and based, at least in part, on the set of conditions included in the flow acceleration request.

    摘要： A method for providing single point-of-presence for a network element includes receiving a packet at a network processor, determining if the packet is to be directed to a particular one of a plurality of traffic processors if a source address of the packet is associated with a subscriber terminal, and determining if the packet is to be directed to the particular one of the plurality of traffic processors if a destination address of the packet is associated with the subscriber terminal. The method further includes distributing the packet to the particular one of the plurality of traffic processors.

    摘要： In one embodiment, a midpoint obtains information from packets by monitoring a communication session between a subscriber side endpoint and a network side provider. The communication session involves a packet flow comprising one or more packets, where a packet comprises tunnel layers. The midpoint establishes one or more target layers of the tunnel layers and performs the following for each tunnel layer at least until a last target layer is reached: identifies a protocol associated with a tunnel layer, parses the packet according to the identified protocol, and extracts target information from the tunnel layer if the tunnel layer is a target layer.

    摘要： At least one first frame of a first data flow is inspected by a general processing unit to at least determine whether a subsequent portion of the first data flow can be delegated to a network processing unit for accelerated processing. A deceleration trigger is defined for the first data flow from the inspection of the first frame. A first subsequent portion of the first data flow is delegated to a network processing unit for accelerated processing based, at least in part, on the defining of the first deceleration trigger. The first deceleration trigger defines at least one first condition that, when met during accelerated processing of the first data flow, prompts returning processing of the first data flow from the network processing unit to the general processing unit for further inspection of subsequent packets.
