摘要： In one embodiment, bridges in a computer network maintain a per-port mapping table for each of its ports, where each mapping table maps, for each virtual connection (of more than 4K) at a respective port, i) frame encapsulation fields that uniquely identify a particular virtual connection at the respective port to ii) a particular multiple spanning tree (MST) instance. The bridges may then compute a checksum of a particular mapping table for a particular port, and share the checksum with a corresponding port interconnected with the particular port (e.g., of another bridge). Upon determining that the mapping tables at the corresponding ports match in response to the checksums matching, frames may then be forwarded between the ports based on the particular mapping table.

摘要： Techniques are provided for managing and distributing communications in a network. At a first switch device arranged in a first configuration in a network, a set of one or more network attributes are determined, which are associated with network communications that the first switch device is interested in receiving from other network devices. The first switch device sends to a controller device an attribute interest message that informs the controller device of the set of network attributes. The first switch device receives a mapping of the network attributes in to one or more identifiers. The identifiers are included in a header of subsequent frames sent in the network. An identifier interest message is then sent to a second switch device arranged in a second network configuration in the network to inform the second switch device of identifiers of the network attributes of which the first device has an interest.

摘要： A router identifies in a data packet an address of a network device. An algorithm determines that the address and a first prefix in a tree data structure match up to a first mask length of the first prefix. The algorithm maintains the first prefix in a temporary storage location if there is a match, and determines whether the address and a second prefix in the tree data structure match up to a second mask length of the second prefix, wherein an external node of the second prefix is linked below an external node of the first prefix, and wherein the second mask length is longer than the first mask length. The algorithm maintains the second prefix as a better match of the address, if the address and the second prefix match up to the mask length of the second prefix.

摘要： In one embodiment, one or more indicia of stress are monitored. Based on the one or more indicia of stress, it is determined a stress condition exists. In response to the stress condition, one or more link aggregation actors and partners are caused to enter a grace state for a grace period. While the one or more link aggregation actors and partners are in the grace state, link aggregation formation is paced on a plurality of links by delaying formation of one or more new link aggregation groups on the plurality of links until a hold is released. Upon expiration of the grace period, the grace state is exited.

摘要： A method of improving luminance transition includes decoding a coded video bitstream around a transition from a first luminance level to a second luminance level; and providing luminance transition enhancement based on a metric indicative of video bitstream. Additionally, an apparatus that improves a luminance transition includes a video decoder and a module that determines a metric indicative of the degree of video coding artifacts in a signal. The apparatus also includes a video processing module that includes a luminance transient enhancement module. The luminance enhancement module provides transition based on at least a value of the metric at the transition.
