Embodiment 1

[0093] Figure 11 is a schematic diagram of a layer-1-based connectivity detection mechanism between service nodes according to a preferred embodiment of the present invention. Such as Figure 11 As shown, the process may include the following steps:

[0094] Step 1. The source service node 1 constructs the SFCOAM connectivity detection message carrying the SFCOAM detection level field, encapsulates it in the Overlay layer, and forwards the connectivity detection message to the next-hop service node 2 along the service function chain , wherein the value of the detection level field carried in the connectivity detection message is 1, that is, based on the connectivity detection between service nodes;

[0095] Step 2: Service node 2 receives the above-mentioned connectivity detection message, and parses out the SFCOAM detection level field from the connectivity detection message, and finds that it is based on level 1; at the same time, it finds that it is running normally, the...

Embodiment 2

[0098] Figure 12 It is a schematic diagram of a Ping mechanism between service nodes based on layer 2 according to a preferred embodiment of the present invention. Such as Figure 12 As shown, the method may include the following steps:

[0099] Step 1. The source service node 1 constructs the SFCOAM Ping message carrying the SFCOAM detection level field, encapsulates it in the Overlay layer, and then forwards the Ping message to the next-hop service node 2 along the service function chain, Among them, the carrying detection level field value is 2, that is, based on the connectivity detection between service function transponders;

[0100] Step 2, service node 2 receives the Ping message, and parses out the SFCOAM detection layer field from the Ping message, finds that it is based on layer 2, and then forwards the SFC encapsulated message to the service function forwarder SFF experienced by the service function chain ;

[0101] Step 3. The above-mentioned SFF checks wheth...

Embodiment 3

[0105] Figure 13 It is a schematic diagram of a Trace mechanism based on a layer-3 service function path according to a preferred embodiment of the present invention. Such as Figure 13 As shown, the method may include the following steps:

[0106] Step 1. The source-side ServiceClassifier constructs a TTL value of 1, encapsulates the SFCOAM Trace message carrying the SFCOAM detection level field in the Overlay layer, and forwards the Trace message to the next-hop service node 1 along the service function chain, where , the carried detection level field value is 3, that is, based on the connectivity detection between the service function SFs managed by the service function forwarder;

[0107]Step 2: Service node 1 receives the Trace message, parses the SFCOAM detection layer field from the Trace message, finds that it is based on layer 3, and then forwards the SFC encapsulated message to the service function forwarding experienced by the service function chain device SFF; ...

Abstract

The invention discloses a processing method and apparatus for detection level information. In the method, a source end service node determines SFC OAM detection level information and packages the SFC OAM detection level information in an SFC OAM detection packet, the SFC OAM detection level information being used for indicating SFC OAM detection among peer entities at the same level in different service nodes; and the source end service node transmits the SFC OAM detection packet to a destination end service node. The technical scheme of the invention can be used for flexible definition and management of OAM detection levels.

Description

technical field [0001] The present invention relates to the communication field, in particular to a processing method and device for detecting hierarchical information. Background technique [0002] Service Function Chaining (SFC for short) is a network technology currently being studied and standardized. Since the data center network has developed into an overlay (Overlay) network, the edge of the network has become the dividing point between the virtual network and the physical network. Among them, the edge of the network may be a server (Server) or a top-of-rack (ToR) switch, and may be a gateway ( Gateway). However, Overlay technology cannot solve all problems. There are still a lot of middleware (Middleware) in the data center, such as: firewall / load balancer, etc. These devices are processed based on user services. If these devices are traversed through tunnels, obviously It is not acceptable. [0003] This deployment model of the data center requires that the virtu...
