Embodiment approach 1

[0119] In this optional implementation, based on the existing framework of ONF and the existing standard interface of the OpenFlow Switch Specification, an OAM implementation method is proposed to solve the fast OAM function that cannot be implemented in the existing SDN standard, so as to meet the requirements of MPLS-TP, etc. International standard requirements.

[0120] This optional embodiment provides a method for realizing the OAM function, which is based on the existing Openflow protocol Packet-out message structure, and carries OAM configuration information in the Packet-out message.

[0121] Such as Figure 10 As shown, a Packet-out message generally includes an Openflow protocol header (hereinafter referred to as header), a port for forwarding equipment to send the message (hereinafter referred to as in_port), and a set of actions to be performed by the specified forwarding equipment after receiving the message (hereinafter referred to as actions), All or part of th...

Embodiment approach 2

[0145] In this optional implementation, in order to solve the problem that the current SDN network cannot complete the fast OAM function, based on the existing interface extension, the fast OAM function of the bidirectional and unidirectional forwarding paths is completed through the newly defined Packet-out message.

[0146] Figure 11 is a schematic diagram of an optional bidirectional forwarding path OAM configured according to an embodiment of the present invention; Figure 12 is a schematic diagram of an optional unidirectional forwarding path OAM configured according to an embodiment of the present invention; Figure 13 It is a schematic diagram of an optional OAM configuration of only one endpoint forwarding device of a bidirectional forwarding path according to an embodiment of the present invention; Figure 14 It is a schematic diagram of an optional OAM that only configures the first-end point forwarding device of a unidirectional forwarding path according to an emb...

Abstract

Disclosed are a method and device for implementing an operations, administration and maintenance function. The method for implementing an operations, administration and maintenance function comprises: a controller carries OAM configuration information in a configuration packet, the OAM configuration information being used for instructing a forwarding device to carry out an OAM function of a path, the path being a path between forwarding devices; the controller sends the configuration packet to the forwarding device. Via the present invention, an OAM function is implemented on a forwarding device level, thereby satisfying OAM high real-time performance requirements.

Description

technical field [0001] The present invention relates to the communication field, in particular, to a method and device for realizing an operation, maintenance and management function. Background technique [0002] Software defined network (SDN for short) is a research hotspot in the field of communication in recent years. The International Standards Organization Open Networking Forum (ONF) drafts SDN-related standard recommendations, focusing on the decoupling between the controller (controller, CP) and the forwarding device (forwarding device, or switcher), and standardizing the controller. The interface with the forwarding plane facilitates joint networking of controllers and forwarding devices from different manufacturers. [0003] The ONF has released the OpenFlow SwitchSpecification, the interface specification between the controller and the forwarding plane. The protocol implemented based on this interface specification is the Openflow protocol. In recent years, the ...
