Embodiment Construction

[0034] On the basis of comprehensive consideration of implementation complexity, wavelength utilization, and whether it supports wavelength broadcasting, the optical path structure of the ring network node provided by the present invention is specially designed for the mode of fixed wavelength transmission and tunable wavelength reception (ie FTTR) . The basic idea of ​​the FTTR mode is to let each network node have some fixed local wavelengths, local data is carried on it, coupled to the ring network fiber, broadcast to each node of the ring network, and finally use the tunable receiving device at the destination node Perform wavelength selective drop. Which wavelength the control destination node drops off is determined by the control information carried on the control wavelength independent of the data wavelength. That is to say, the add port of each network node is fixedly assigned a wavelength, and a tunable receiving device is used at the receiving end to select the dat...

Description

technical field [0001] The present invention relates to an Optical Burst Switching Ring Network (OBSRN, Optical Burst Switching Ring Network) node optical path structure, in particular to an Optical Burst Switching Ring Network based on a Fixed Transmitter Tunable Receiver (FTTR, Fixed Transmitter Tunable Receiver) working mode A node optical path structure belongs to the technical field of optical communication. Background technique [0002] With the rapid development of network technology, the communication service itself is undergoing profound changes, and the data service represented by the Internet begins to exceed the traditional voice service. The self-similarity and burstiness of the data service itself make the traditional time-division multiplexing-based optical communication technology no longer the best choice, and the massive amount of information to be transmitted in the data service also makes the bandwidth of the traditional network in danger of exhaustion. ...
