Embodiment approach 1
[0119] In this optional implementation, based on the existing framework of ONF and the existing standard interface of OpenFlowSwitchSpecification, an OAM implementation method is proposed to solve the fast OAM function that cannot be implemented by existing SDN standards, so as to meet international standards such as MPLS-TP Require.
[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 the reserved or filled bytes (her...
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...
