Method and System for Encapsulating Flow Identifier

Abstract

Disclosed is a method and system for encapsulating a flow identifier. The method for encapsulating a flow identifier comprises: in the case where flow table matching is successfully performed on a packet, an OpenFlow switch adds a flow identifier to the packet; and the OpenFlow switch invokes a pre-saved function entry to assign a value to the flow identifier, so as to complete the encapsulation of the flow identifier. The disclosure achieves the effect of enabling an OpenFlow network node to take a hash calculation result of some fields of an original packet before encapsulation as the assignment of a new added flow identifier, which is required by the encapsulation of the flow identifier.

Dependencies are inferred from the claim text.
