Method and apparatus providing flow control using on-off signals in high delay networks

摘要

A method and apparatus controlling, either individually or in the aggregate, traffic flows associated with a plurality of queues by transmitting traffic source FlowON messages at first times selected to avoid queue underflow conditions, and traffic source FlowOFF message at second times selected to avoid queue overflow conditions, where the first and second times are determined as a function of delay time D of a link supporting the traffic source.

1. A method for controlling traffic flows associated with a plurality of active queues, the method comprising:
for each active queue, transmitting toward a corresponding traffic source a FlowON message at first times selected to avoid a queue underflow condition; for each active queue, transmitting toward said corresponding traffic source a FlowOFF message at second times selected to avoid a queue overflow condition; said first and second times being determined as a function of delay time D of a link between said each active queue and said corresponding traffic source, wherein time intervals between transmissions of any two messages out of a plurality of FlowON and FlowOFF messages is varied, said plurality of FlowON and FlowOFF messages being an integer of at least more than two and including said FlowON message and said FlowOFF message.
