Problems solved by technology

[0009] Using the above scheme, although the delay can be accurately calculated, the transponder needs to report the timestamp to the controller twice, which increases the burden on the control channel

Abstract

The embodiments of the present invention disclose a network delay detection method, a device and a system. The method comprises the steps of sending an operation administration and maintenance (OAM) detection message to a transponder in a forwarding network by a controller; recording the first moment T1 of sending the OAM detection message; receiving a response message returned from the transponder by the controller; recording the fourth moment T4 of the response message reaching the controller, wherein the load of the response message contains the second moment T2 of the OAM detection message reaching the transponder and the third moment T3 of the response message reaching the transponder; and calculating the network delay according to any two moments out of the first moment T1, the second moment T2, the third moment T3 and the fourth moment T4 by the controller. In this way, the controller receives the response massage only once, so that the resource of control channels is saved.

Description

technical field [0001] The present invention relates to the field of communication technologies, in particular to a network delay detection method, device and system. Background technique [0002] In the network architecture of SDN (Software Defined Network, software-defined network), it is usually divided into three parts: APP (Application, application program) application, controller, and forwarder. The SDN (Service dialling number) controller opens services to APP applications through northbound interfaces such as Restful and NetConf. At the same time, the controller collects the underlying physical network topology, performs centralized calculations, and controls the underlying transponders through southbound interfaces such as Openflow. The SDN system architecture is usually shown in the following figure: [0003] The business application of the APP is opened to the APP by the controller in the north direction. According to the implementation method of Openflow SDN, t...
