Embodiment Construction

[0061] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only some, not all, embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without creative efforts fall within the protection scope of the present invention.

[0062] Before introducing the present invention, first briefly introduce the background technology and technical problems of the present invention. At present, in order to alleviate the impact of the path construction delay on the blocking performance of the network, a strategy of wavelength reservation is usually used when resource allocation is performed, and the commonly used wavelength reservation method is Source-Initiated Reservation (Source-Initiated Reservat...

Abstract

An embodiment of the invention provides a wavelength distribution method and device, relates to a field of communication technology and solves a problem of wavelength reserve conflict in the prior art. The method includes receiving path messages carrying a service type, a target path and an available wavelength set, wherein the service type is corresponding to a service requesting target path establishing and the available wavelength set is a set of available wavelength on each link contained by the target path; determining the service level of the service type based on the service type; obtaining the wavelength occupancy rate of the wavelength resource in the whole network; if the hop count of the target path is greater than 1, selecting a reserve wavelength from the available wavelength set based on the service level, the wavelength occupancy rate and M; carrying the wavelength in the reserve message and returning the reserve message according to the target path so as to enable each node in the target path to reserve the reserve wavelength.

Description

technical field [0001] The present invention relates to the technical field of communications, in particular to a wavelength allocation method and device. Background technique [0002] At present, in the intelligent optical network, there are usually multiple nodes from one node to another node, that is, there are multiple paths from the source node to the destination node, and usually the source node will pass the path calculation unit communication protocol PCEP sends a path computation request message to Path Computation Element (PCE), and PCE calculates an explicit path between the source node and the destination node according to the constraints of the path construction request, and returns the explicit path to the source node . Afterwards, the source node sends a path message, and the next node in the explicit path collects the available wavelengths on the link with the source node and forwards the path message. Similarly, other nodes in the explicit path collect The...
