A kind of wavelength detection method and device

Abstract

The present invention provides a wavelength detection method and device. The channel resolver includes: a processor, a memory connected to the processor, and a wavelength table of a receiving channel is set in the memory. The wavelength table includes a plurality of wavelengths. The method includes: S11: processing The receiver receives the wavelength setting instruction sent by the SDN controller; S12: According to the wavelength setting instruction, read the wavelength table in the memory, set the wavelength selection switch of the receiving channel to the target wavelength that has not been set in the wavelength table, and set the result Send to the SDN controller; S13: Use the target wavelength to monitor the response data returned by the fiber switch to the handshake command sent by the SDN controller on the receiving channel, if the response data is detected, and send the response data to the SDN controller, so that When the SDN controller verifies that the response data is correct, it determines that the detection is successful; otherwise, executes S11‑S13 until it is determined that the detection is successful. In this solution, the fixed wavelength of the optical fiber switch can be detected.

Description

technical field [0001] The invention relates to the field of computer technology, in particular to a wavelength detection method and device. Background technique [0002] With the continuous development of computer communication technology, a new network architecture has emerged, which includes: a channel resolver, multiple optical fiber switches that use multi-core optical fibers as the transmission medium and are connected to the channel resolver by ring wiring 1. An SDN (Software Defined Network, software defined network) controller connected to each port of the channel resolver. This network architecture is simple and scalable. [0003] The working mode of the above-mentioned network architecture includes: the SDN controller uses the Tx port of the channel resolver to send control data to each optical fiber switch, the optical fiber switch responds to the control data, and sends the response data to the channel resolver, so that the channel resolver forwards to the SDN...
