System and method for congestion control signaling

摘要

Systems and methods for controlling congestion on a packet data network are provided. The congestion control may be implemented between any two network nodes where a regulation of a data flow is desired to prevent a device overload from occurring. In order to provide regulation of a data flow, congestion control states are used where each state regulates the data flow in a specified manner. State transitions may occur in response to messages that include congestion information detected at a network node.

主权项

1. A system comprising:
a first node that is configured to send data flows including packets of data in a packet data network to a second node in the packet data network; the first node configured to receive a congestion control message from the second node indicating congestion information regarding congestion at the second node, and in response to the congestion information, the first node transitioning to a first congestion control state of a plurality of congestion control states; and the first node configured to regulate data flow to the second node based on the congestion control state and where the plurality of congestion control states each provide a different level of congestion control with at least one congestion control state of the plurality of congestion control states providing at least that some types of packets are stopped and some types of packets are rate-limited depending on a plurality of priority levels associated with each data flow of packet data.
