Abstract

The invention comprises a method and apparatus that prevents the activation of a congestion controlling process that would otherwise be activated in response any packet loss condition. The congestion controlling process is inhibited when a congestion parameter associated indicates that the packet loss condition is not caused by congestion.

Claims (6)

1. At a node that would otherwise activate a congestion control process in response to any packet loss condition, a method comprising the steps of:

storing a value of a congestion parameter on the node, wherein the value of the congestion parameter indicates whether a communication path is congested or uncongested; and

in response to detecting a packet loss condition, preventing activation of the congestion control process at the node when the value of the congestion parameter indicates that the communication path is uncongested.

2. An apparatus, comprising:

a memory for storing a value of a congestion parameter associated with a communication path, wherein the value of the congestion parameter indicates whether the communication path is congested or uncongested; and

a processor for preventing activation of a congestion control process in response to detecting a packet loss condition, wherein the processor prevents activation of the congestion control process when the value of the congestion parameter associated with the communication path indicates that the communication path is uncongested.
