Patent number: 10637970Abstract: A packet processing method and an apparatus are provided. A first SFC proxy of a first SF entity splits a first packet to obtain a first original packet and a first SFC header, and the first SFC proxy sends the first SFC header to a second SFF. The first SF entity processes the first original packet to obtain a second original packet, and sends the second original packet to a service classifier. The service classifier sends, to the second SFF, a second packet that is obtained after the service classifier adds a second SFC header to the second original packet. The second SFF changes the second SFC header in the second packet into the first SFC header. In this way, a first packet carrying a first SFC header can be transmitted in a network architecture in which a legacy SF exists, so that the legacy SF becomes compatible.Type: GrantFiled: June 9, 2017Date of Patent: April 28, 2020Assignee: Huawei Technologies Co., Ltd.Inventors: Jianjie You, Haibin Song
