Title:
METHOD AND DEVICE FOR COMPUTING GLOBAL CONCURRENT OPTIMIZATION PATH, AND COMPUTER READABLE STORAGE MEDIUM
Document Type and Number:
WIPO Patent Application WO/2021/027519
Kind Code:
A1
Abstract:
A method and device for computing a global concurrent optimization path, and a computer readable storage medium. The method comprises: a path computation element (PCE) sequentially computes an actual path of each service in one or more services on the basis of a topological structure as an actual best path; the PCE sequentially allocates actual spectrum resources for the actual paths as actual best spectrum resources; the PCE computes actual target values of all services according to a target function as actual best target values; the PCE reorders service subsets in the one or more services, re-computes an actual path of each service in the service subsets and reallocates a spectrum resource, re-computes actual target values of all services, updates the actual best target values, and updates the actual best paths and actual best spectrum resources, until the number of re-computations reaches a threshold and/or the differences between the actual best target values and a minimum target value of all services are less than or equal to a predetermined value, wherein each actual best target value is the minimum value among all of the computed actual target values.
