Embodiment Construction

[0021] The basic principle of the embodiment of the present invention is to compare the equipment tolerance value of each service receiving end carried by the WDM network with the final constraint parameter value of the receiving end of each service, and determine that the equipment tolerance value of the receiving end is lower than the receiving end according to the comparison result. The lower limit of the terminal's final constraint parameter value or the service that the receiving end's device tolerance value is higher than the receiving end's final constraint parameter value upper limit, calibrate the Links that these services pass through, and adjust the constraint parameter value in sections with Link (link) as the unit. After the adjustment of a Link section is completed, the constraint parameter values ​​of all services on this section are available on this section. After all online Link adjustments are completed, all services are available at the same time.

Abstract

The invention provides a method and a device for configuring equipment in wavelength division multiplex (WDM) networks. The method comprises the steps as follows: a. final constrained parameter values in all service receiving ends are confirmed according to constrained parameter values in the links, through which all services loaded by WDM networks pass; b. the final constrained parameter values in all service receiving ends and equipment tolerance values in all service receiving ends are compared, and links through which sub-par services pass are regulated till the final constrained parameter values in all service receiving ends fall within the range of the equipment tolerance values in all service receiving ends. The technical proposal provided by the invention can optimize network planning process, and can realize the goal of reducing the workload of model computation, so as to save planning cost and meet the requirements raised by a large-scale WDM network planning; meanwhile, the technical proposal provided by the embodiment of the invention can also optimize the specifications of the equipment, thereby realizing the goal of reducing capital expenditures of the networks.

Description

technical field [0001] The invention belongs to the field of network technology, in particular to the technical field of wavelength division multiplexing (Wavelength Division Multiplexing). Background technique [0002] With the continuous development of the market and technology and the emergence of the Internet, voice services based on circuit switching are no longer the only form of service. ATM (Asynchronous Transfer Mode) services based on cell switching, Ethernet services / IP services based on packet switching, digital multimedia services, and value-added services have become rapidly growing new service forms. It is inevitable that multi-service, multi-protocol, multi-rate and multi-format will coexist in the metropolitan area business network. The metro transmission network is an extension of the backbone transport network in the metro area, and the metro transport network is a platform connecting the metro service network. The emergence of new services and new proto...
