METHOD AND DEVICE FOR SENDING AND RECEIVING FLOW SPECIFICATION RULE

摘要

Provided in embodiments of the present invention are a method and device for sending and receiving the flow specification rule. A first network device receives a flow specification rule ORF record sent from a second network device after determining that the second network device has the ability of sending the flow specification rule ORF record to the first network device, the flow specification rule ORF record being used for the first network device to filter the flow specification rule to be sent to the second network device. When the flow specification rule is available to be sent to the second network device by the first network device, the first network device filters the flow specification rule to be sent to the second network device according to the flow specification rule ORF record in order to send only the flow specification rule satisfied the flow specification rule ORF record filtering condition to the second network device, thereby solving the problem of resources waste caused by the network device of sending numerous invalid flow specification rules.
