Abstract

Embodiments of the present invention provide a fault handling method and device, which relate to the field of communication technology and are used to solve the problem of how the controller manages the transponder when the management channel between the transponder and the controller is abnormal. The method includes: when the first transponder detects that the management channel between the controller and the controller is abnormal, sending a proxy management request to the neighbor transponder through its normal working OpenFlow port; receiving a proxy management response sent by the second transponder; Establishing a first OpenFlow connection with the second forwarder; receiving a management command sent by the second forwarder through the first OpenFlow connection, and executing corresponding management actions according to the management command. The embodiments of the present invention are used for troubleshooting when the management channel between the transponder and the controller is abnormal.

Description

technical field [0001] The present invention relates to the technical field of communications, in particular to a fault handling method and equipment. Background technique [0002] Software Defined Network (full name in English: Software Defined Network, referred to as: SDN) is an implementation of network virtualization. Its core technology, OpenFlow, realizes flexible control of network traffic by separating the control plane of network equipment from the forwarding plane. , making the network more intelligent. [0003] In many scenarios of the OpenFlow network, the controller uses out-of-band management to control the transponder, that is, the physical channel through which the controller transmits control information to the transponder is different from the physical channel through which the transponder transmits data. However, when the management channel between the forwarder and the controller is abnormal, the forwarder will enter a disconnected state, the controller ...
