Abstract
A system controls the flow of traffic in a network, especially an Ethernet-based network. The system receives a flow control message indicating that traffic flow to a downstream device is to temporarily cease and determines an appropriate flow control action based on a set of control policies in response to the flow control message. The system then performs the selected flow control action.
Claims19
In a network comprising a plurality of nodes, a method, performed by one of the nodes, for controlling a flow of traffic in the network, the method comprising:
- receiving, from a downstream node, a flow control message indicating that a flow of traffic is to temporarily cease;
- determining an appropriate flow control action based on at least one of a plurality of control policies;
- and
- performing the appropriate flow control action.
A system for controlling a flow of traffic in a network, comprising:
- means for receiving a flow control message, the flow control message requesting that a transmitting device temporarily stop transmitting data;
- means for determining an appropriate flow control action based on at least one of a set of predetermined policies in response to the flow control message;
- and
- means for performing the appropriate flow control action.
A network device comprising:
- an input interface configured to receive a flow control signal;
- a memory configured to store a set of control policies;
- and
- flow control logic configured to:
- determine a flow control action based on one or more of the control policies in response to the flow control signal, and
- cause the selected action to be performed.
A computer-readable medium containing instructions for controlling one or more processors to perform a method for controlling traffic flow in a network, the method comprising:
- receiving a flow control message, the flow control message requesting that a transmitting device temporarily stop transmitting data;
- determining an appropriate flow control action based on at least one of a set of predetermined policies;
- and
- performing the appropriate flow control action.
