SERVICE PACKET PROCESSING METHOD, APPARATUS AND SYSTEM

摘要

The present invention belongs to the technical field of Internet. Disclosed are a service packet processing method, an apparatus and a system. The method comprises: a first service atom receiving a second packet sent by a central switching device, wherein the second packet is encapsulated with a first service packet, and the second packet also comprises a first service path identifier; the first service atom processing a first service according to information in the first service packet to obtain a first processing result; the first service atom querying a first path switching table entry according to the first processing result and the first service path identifier so as to obtain a second service path identifier; and the first service atom sending a third packet to the central switching device, wherein a source device identifier of the third packet is a device identifier of the first service atom, the third packet is encapsulated with the second service packet, and the third packet comprises the second service path identifier. According to the present invention, a service range that can be processed by a service processing system comprising multiple service atoms can be expanded.
