Abstract

A method is provided for queuing packets. A packet may be received and its flow identified. It may then be determined whether a flow queue has been assigned to the identified flow. The identified flow may be dynamically assigning to an available flow queue when it is determined that a flow queue has not been assigned to the identified flow. The packet may be enqueued into the available flow queue.

Claims

1. A method for queuing packets, comprising:

receiving a packet;

identifying a flow associated with the packet;

determining whether a flow queue has been assigned to the identified flow;

dynamically assigning the identified flow to an available flow queue when it is determined that a flow queue has not been assigned to the identified flow; and

enqueuing the packet into the available flow queue.
