Abstract
A service routing packet processing method, apparatus and system. The method includes obtaining, by a first service router (SR), a first service routing packet, where the first service routing packet includes path identification information and identification information of a service node (SN), and sending, by the first SR, the first service routing packet to the SN.
Claims17
A service routing packet processing method, comprising:
- obtaining, by a first service router (SR), a first service routing packet, wherein the first service routing packet comprises path identification information identifying a service path, and identification information of a service node (SN) in the service path;
- and
- sending, by the first SR, the first service routing packet to the SN based on the path identification information, and the identification information of the SN;
- and
- wherein the sending the first service routing packet comprises:
- querying, by the first SR, a first entry according to the identification information of the SN to obtain a first underlay network address, wherein the first underlay network address is an address of the SN in a first underlay network, wherein the first entry comprises the identification information of the SN and the first underlay network address;
- obtaining, by the first SR, a first underlay network packet transmitted on the first underlay network according to the first service routing packet and the first underlay network address, wherein the first underlay network packet comprises the first underlay network address and the first service routing packet;
- and
- sending, by the first SR, the first underlay network packet to the SN according to the first underlay network address.
6 more elements
A service router (SR), comprising:
- a processor;
- and
- a non-transitory computer-readable storage medium coupled to the processor and storing programming instructions for execution by the processor, the programming instructions including instructions to:
- obtain a first service routing packet, wherein the first service routing packet comprises path identification information identifying a service path and identification, and information of a service node (SN) in the service path;
- and
- send the first service routing packet to the SN based on the path identification information, and the identification information of the SN;
- and
- wherein the instructions to obtain the first service routing packet include instructions to:
- query a first entry according to the identification information of the SN to obtain a first underlay network address, wherein the first underlay network address is an address of the SN in a first underlay network, wherein the first entry comprises the identification information of the SN and the first underlay network address;
- obtain a first underlay network packet transmitted on the first underlay network according to the first service routing packet and the first underlay network address, wherein the first underlay network packet comprises the first underlay network address and the first service routing packet;
- and
- send the first underlay network packet to the SN according to the first underlay network address.
9 more elements
A network system, comprising:
- a first service router (SR);
- and
- a service node (SN) in signal communication with the first SR;
- wherein the first SR is configured to:
- obtain a first service routing packet, wherein the first service routing packet comprises path identification information identifying a service path, and identification information of the SN of the service path;
- and
- send the first service routing packet to the SN based on the path identification information, and the identification information of the SN;
- and
- wherein the first SR being configured to send the first service routing packet comprises the first SR being configured to:
- query a first entry according to the identification information of the SN to obtain a first underlay network address, wherein the first underlay network address is an address of the SN in a first underlay network, wherein the first entry comprises the identification information of the SN and the first underlay network address;
- obtain a first underlay network packet transmitted on the first underlay network according to the first service routing packet and the first underlay network address, wherein the first underlay network packet comprises the first underlay network address and the first service routing packet;
- and
- send the first underlay network packet to the SN according to the first underlay network address.
