A transmission method and system for an optical burst transport network are disclosed in the present document. The method includes: acquiring a topology of a mesh OBTN network, and generating one or more logical sub-networks according to the topology of the mesh OBTN network; a predetermined master node in the mesh OBTN network updating bandwidth maps for all logical sub-networks; the predetermined master node is a node, which all control channels pass through, in all the nodes of the mesh OBTN network.

Transmission method and system for optical burst transport network

A method for detecting an optical signal-to-noise ratio (OSNR). A wavelength label loading end () loads a wavelength label signal in an optical signal, and sends a loading modulation depth of the wavelength label signal to an OSNR detection end () through a wavelength label channel or an optical monitoring channel. The OSNR detection end () obtains a loading modulation depth of a wavelength label signal loaded in each wavelength optical signal, parses the wavelength label signal to obtain a current modulation depth of the wavelength label signal, and obtains an OSNR value of each wavelength optical signal according to the loading modulation depth and the current modulation depth of the wavelength label signal. A system and device for detecting an OSNR applicable to OSNR tests of present optical signals with high rates of 40 G, 100 G, etc., and in particular to OSNR tests of polarization multiplexing optical signals.
