Abstract

A service routing packet processing method, apparatus and system. The method includes a first service router (SR) obtains a first service routing packet, and the first service routing packet comprises path identification information and identification information of a service node (SN). The first SR sends the first service routing packet to the SN. A system includes a first service router (SR) and a service node (SN) in signal communication with the first SR. The first SR is configured to obtain a first service routing packet comprising path identification information and identification information of a service node (SN), and send the first service routing packet to the SN.

Dependent claims

A service routing packet processing method, comprising:

receiving, by a service node (SN), a first service routing packet via a source interface;
obtaining, by the SN, a second service routing packet by performing service processing on the first service routing packet, the service processing comprising a load balancing function, network address translation (NAT) function, network firewall function, a uniform resource locator (URL) filtration function, or a combination thereof;
and
sending, by the SN, the second service routing packet via a destination interface obtained according to a relationship between the source interface and the destination interface;
wherein the receiving the first service routing packet via the source interface comprises:
receiving, by the SN, an underlay network packet from a service router (SR) via the source interface, the first service routing packet is encapsulated in the underlay network packet, and wherein the underlay network packet is a packet of an underlay network between the SN and the SR;
and
obtaining, by the SN, the first service routing packet by parsing the underlay network packet.
