    摘要: Techniques for finding an optimized local repair path that may be used to signal a local repair connection for a protected connection. The optimized local repair path starts at a node in the path associated with the protected connection and ends at a merge point node in the path associated with the protected connection that is downstream from the start node. Various techniques may be used for finding an optimized local repair path.

    摘要: Techniques for authenticating clients of differing capabilities in an efficient manner. Two or more authentication techniques, including one preferred authentication technique, are initiated to run in parallel to authenticate a client. Upon determining that the client can support the preferred authentication technique, the preferred technique is used to authenticate the client and the other authentication techniques are aborted. If it is determined that the client cannot support the preferred authentication technique, then one of the other authentication techniques is used to authenticate the client. In this manner, based upon the capabilities of the client, an appropriate authentication technique is used to authenticate the client in an efficient manner.

    摘要: Techniques that offer enhanced diversity in the selection of paths (e.g., ECMP paths) and/or ports from ports associated with trunks for forwarding data traffic. In one embodiment, one or more functions are used to generate a result. A first portion of the generated result may be used as an index (e.g., ECMP index) for selecting a path (e.g., an ECMP path) from multiple possible paths for forwarding a packet. A second portion of the generated result, different from the first portion, may be used as an index (trunk index) for selecting an output port from multiple output ports associated with a trunk for forwarding a packet. In this manner, selected portions of the generated result may be used as indices, one for selecting a path and another for selecting a trunk port for forwarding packets such that the two indices are not the same and are not dependent upon one another.

    摘要: One embodiment provides a system that facilitates bandwidth-profile enforcement. During operation, the system indicates a packet's compliance with a bandwidth profile based at least on available high-compliance tokens and medium-compliance tokens. The system further accounts for overflow tokens from a respective class of service (CoS) and distribute an overflow token to another CoS priority level based on the overflow token's CoS information.

    摘要: A system, method and apparatus for providing multiple access modes in a data communications network includes a network access device having a plurality of input ports, a plurality of output ports, and a switching fabric for routing data received on the plurality of input ports to at least one of the plurality of output ports. Control logic within the network access device is adapted to determine whether a user device coupled to one of the plurality of input ports supports a user authentication protocol used by a host network. If the user authentication protocol is not supported, then the input port to which the network access device is coupled is placed in a semi-authorized access state that limits access to a pre-configured network accessible via the host network.
