  • Patent number: 7835362
    Abstract: The present invention provides methods and systems for the management of sequence-sensitive, connection-oriented traffic on a multi-link aggregated port. The methods include: at a first end of a multi-link aggregated port, selectively enabling a first constituent link of a plurality of constituent links to transmit data traffic in a first direction via a transmit state block associated with the first constituent link; and, at the first end of the multi-link aggregated port, selectively enabling the plurality of constituent links to receive data traffic from a second direction via a plurality of receive state blocks associated with the plurality of constituent links.
    Type: Grant

  • Patent number: 7808979
    Abstract: The present invention provides methods and systems for aggregating packets combining connection-oriented and connection-less techniques. The methods and systems of packet aggregation utilize connection-oriented techniques to forward data from multiple clients to an access switch and utilize connection-less techniques to forward data from the access switch to the multiple clients. Advantageously, the methods and systems of the present invention combine connection-oriented and connection-less aggregation techniques in a packet aggregation platform to provide for a well-understood per-subscriber provisioning model, to maintain per-subscriber visibility, to allow layer 2 protocol internetworking, to remove connection count limitations imposed by adjacent equipment, and to maintain security aspects of connection-oriented aggregation techniques.
