Description

technical field [0001] The invention relates to the field of network technology, in particular to a data center transmission system, a method and a device for realizing control in the system. Background technique [0002] With the development of the network architecture, the existing network architecture carries more and more Internet services, resulting in various types of services and huge traffic demands. [0003] The existing network architecture is ITU-T-related OTN (Optical Transport Network, Optical Transport Network) network architecture, the standards used include G.872; G.798.1; G.798; G.709; G.672; G .680. [0004] Such as figure 1 As shown, the OTN network architecture adopts electrical cross-connect and optical cross-connect for hybrid networking. Among them, the optical cross-connect matrix equipment mostly adopts reconfigurable optical add-drop multiplexers, and the electrical cross-connect matrix equipment uses ODU k Mapping, multiplexing, and crossing are...

AI Technical Summary

Problems solved by technology

[0005] However, in the OTN network architecture, since the optical cross-connect matrix equipment uses a reconfigurable optical add-drop multiplexer (ROAM), there is a serious defect of high networking complexity

[0006] For example, if figure 2 As shown, taking the currently more commonly used 9-dimensional WSS ROAM as an example, to build a network with 3 local dimensions + 4 optical directions, no less than 37 optical layer components and 282 optical fiber connections are required. The establishment and subsequent maintenance very difficult
