COMMUNICATION METHOD, INFORMATION PROCESSING APPARATUS, COMMUNICATION SYSTEM, COMMUNICATION TERMINAL, AND PROGRAM

摘要

A communication method identifies a packet flow based on a predetermined rule and processes a packet belonging to the identified packet flow. The communication method comprises: setting a plurality of first rules that respectively identify a plurality of packet flows in a first node; and setting, upon change of forwarding paths of the plurality of packet flows, a second rule that identifies the plurality of packet flows as a group in a second node on the changed forwarding paths. The amount of information stored in a communication apparatus for processing packet flows can be reduced and easy change of a forwarding path can be realized.
