Embodiment 1

[0038] Based on the above technical principle, the embodiment of the present application provides a route distribution method and a route distribution device, which are applied to such as figure 1 shown in the ROADM network or other similar figure 1 In the ROADM network of the shown network architecture, the effect of allocating a physical route that is more in line with the usage requirements for the target service of the route to be allocated is achieved.

[0039] It should be noted that the route allocation device referred to in this application may have other names for the device or equipment that executes the route allocation method provided in this application during specific implementation.

[0040] And in a specific implementation, the route distribution device may also be a device independent of each node of the ROADM network. The route allocation device can communicate with one or more nodes of the ROADM network through a communication interface, so as to send routi...

Embodiment 2

[0148] An embodiment of the present application provides a route distribution device configured to execute the route distribution method provided in Embodiment 1 above. Such as Figure 8 As shown in FIG. 1 , it is a schematic diagram of a possible structure of the route allocation device provided in the embodiment of the present application. Specifically, the route distribution device 20 includes: a determination unit 201 , a query unit 202 , and a route generation unit 203 . in:

[0149] A determining unit 201, configured to determine a target service level corresponding to the target business;

[0150] The query unit 202 is configured to query m physical routes capable of carrying target services in the reconfigurable optical add-drop multiplexer ROADM network; wherein, m is a positive integer;

[0151]The route generation unit 203 is configured to select the target physical route that meets the restriction from the m physical routes after the query unit 202 finds m physi...

Abstract

Embodiments of the present application provide a route allocation method and device, which relate to the communication field. The application can quickly and accurately complete the work of planning routes for target services. The route allocation method includes: determining the target service level corresponding to the target business; wherein, the target service level is one of a plurality of preset service levels; in the reconfigurable optical add-drop multiplexer ROADM network, the query can carry m physical routes of the target business; where m is a positive integer; select the target physical route that meets the restriction from the m physical routes; the restriction includes: the restriction on the physical route corresponding to the target service level; the target physical route refers to A physical route used to transmit target services. This application is applied to routing distribution in ROADM network.

Description

technical field [0001] The present application relates to the communication field, and in particular to a method and device for routing assignment. Background technique [0002] With the rapid development of the Internet, network traffic continues to grow at a high speed, and customers' demand for channels of WDM (Wavelength Division Multiplexing, wavelength division multiplexing) networks is also increasing. In addition, in order to meet the development of services and traffic in WDM networks, the structure of WDM networks often needs to be adjusted. The WDM network scale is getting larger and larger, and the channel scheduling of the WDM network is also becoming more and more frequent. The traditional network structure of point-to-point WDM links cannot meet the needs of future and business development. [0003] Relying on OTN (Optical Transport Network, Optical Transport Network) electrical cross-connect scheduling can meet certain requirements, but OTN electrical cross-...
