Abstract

A system and method of scheduling delivery of a packet for transmission from a network device, is provided. The packet is classified according to type, and queued with other packets of the same type. Each packet is associated with an expiry time, after which it will not be delivered. A queue tracker monitors the queues and removes expired packets.

Claims

4-1. The method of claim 4, wherein, if said packet is of type “

voice”

, said time associated with said packet will follow a pareto distribution model.

5. The method of claim 5, wherein, if said packet type is of type “

data”

, said time associated with said packet will follow a exponential distribution model.

6. A system for scheduling a packet for transmission, comprising:

(a) a queue manager;

(b) a packet classifier for classifying a packet into a type, comprising the set of;

voice, data, audio, and video; and

associating a time for said packet;

(c) for each of said types, a corresponding queue to receive packets of said type for transmission, from which said queue manager determines said packet to be transmitted; and

(d) a queue tracker for reporting expired packets to said queue manager.
