Description

technical field The invention belongs to the field of optical burst switching (Optical Burst Switching, OBS) network, especially the core node structure in the OBS network. Specifically, it relates to an optical cross connection (Optical Cross Connection, OXC) structure used in a core node of an OBS network and a control method for the OXC. technical background With the maturity of Dense Wavelength Division Multiplexing (DWDM) technology, the capacity of communication network is getting bigger and bigger. At present, a single optical fiber can carry dozens or even hundreds of transmission channels, and the transmission capacity of each transmission channel can reach 40Gbps or even higher. Although the transmission capacity of the communication network has been able to meet the needs of various services, it also brings pressure on the development of the switching system. At present, the switching capacity of network nodes is insufficient, which has become a bottleneck restr...
