FLOW-SPECIFIC FAILURE DETECTION IN SDN NETWORKS

摘要

Techniques for performing flow-specific failure detection in SDN networks are provided. In one embodiment, a computer system (e.g., an SDN controller) can determine a flow to be monitored in a network. The computer system can then transmit first and second messages to first and second network devices in the network respectively, where the first network device is an upstream device in the flow, where the second network device is a downstream device in the flow, and where the first and second messages instruct the first and second network devices to collect local data rate information for the flow.

1. A method comprising:
determining, by a computer system, a flow to be monitored in a network; and transmitting, by the computer system, first and second messages to first and second network devices respectively, wherein the first network device is an upstream device in the flow, wherein the second network device is a downstream device in the flow, and wherein the first and second messages instruct the first and second network devices to collect local data rate information for the flow.
