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 layer2protocol internetworking, to remove connection count limitations imposed by adjacent equipment, and to maintain security aspects of connection-oriented aggregation techniques.
