METHOD FOR GENERATING ENTRY, METHOD FOR RECEIVING PACKET, AND CORRESPONDING APPARATUS AND SYSTEM

摘要

Embodiments of present invention provide a method for generating an entry, and the method includes: receiving, by a stream forwarding apparatus, a first packet, where the stream forwarding apparatus is an apparatus in a network architecture in which controlling and forwarding are separated; searching, a flow table for a first entry matching the first packet, where a set formed by fields that are in the first entry and match the first packet is a first set; generating, a second entry according to the first entry, where a set formed by fields that are in the second entry and match the first packet is a second set, the first set is a subset of the second set. According to the technical solution in embodiments, the stream forwarding apparatus obtain an exact matching entry without interacting with a control plane apparatus through a control channel.

1. A method for generating an entry, the method comprising:
receiving, by a stream forwarding apparatus, a first packet, wherein the stream forwarding apparatus is a stream forwarding apparatus in a network architecture in which controlling and forwarding are separated; searching, by the stream forwarding apparatus, a flow table for a first entry matching the first packet, wherein a set formed by fields that are in the first entry and match the first packet is a first set; and generating, by the stream forwarding apparatus, a second entry according to the first entry, wherein a set formed by fields that are in the second entry and match the first packet is a second set, the first set is a subset of the second set, and the first set is not equal to the second set.
