Embodiment 1

[0053] This embodiment provides an OAM method for SFC, which mainly includes the following operations:

[0054] When the source service node performs OAM operation on the alias information, the source service node determines the SFC or service function path bound to the alias information;

[0055] The source node device performs the SFCOAM operation on the determined SFC or service function path, generates a corresponding OAM message and sends it to the destination service node of the OAM operation.

[0056] Wherein, the SFCOAM involved in this embodiment includes the SFCPing function, or the SFCTrace function, or the SFCBFD function, or the SFC connectivity detection function, etc.; the implementation mechanism may follow the relevant specifications of the SFCOAM. However, the node device involved in this embodiment may be a service classifier, or any service node in a service function chain or a service function path.

[0057] Preferably, the above method may further includ...

Abstract

The invention discloses an SFC OAM method and a node device, and relates to the field of Internet equipment. The SFC OAM method comprises that when a source-end service node carries out OAM operation on alias information, the source-end service node determines an SFC or a service function path bound to the alias information; and the source-end service node carries out OAM operation on the determined SFC or service function path to generate a corresponding OAM message and send the OAM message to a target-end service node of the OAM operation. According to the technical scheme of the invention, an operator can obtain link information of the service chain simply and rapidly, and diagnose and locate the link information of the service chain, and thus, different SFC OAM can be realized rapidly and simply.

Description

technical field [0001] The present invention relates to the field of Internet equipment, and in particular, relates to a method for realizing operation, administration and maintenance (OAM) of a service function chain and a node device. Background technique [0002] SFC (Service Function Chaining, service function chain) is a network technology that is currently being studied and standardized. Since the data center network has developed into an overlay network, the edge of the network has become the dividing point between the virtual network and the physical network. The edge of the network is the server or ToR, and possibly the gateway. However, the Overlay technology does not solve all problems. There are still a lot of middleware in the data center, such as firewalls / load balancers, etc. These devices are processed based on user services. It is obviously impossible to traverse these devices through tunnels. [0003] This deployment model of the data center requires that ...
