Title:
RESOURCE ALLOCATION METHOD IN MULTI-CORE OPTICAL FIBER NETWORK
Document Type and Number:
WIPO Patent Application WO/2021/088230
Kind Code:
A1
Abstract:
Provided in the present invention is a resource allocation method in a multi-core optical fiber network. Said method provides an evaluation mechanism of inter-core crosstalk, establishes, according to the evaluation mechanism, a joint optimization method targeting the minimum crosstalk and the minimum spectrum resource occupation in an optical network, and solves the problems of route computing, core selection and spectrum allocation in a multi-core optical fiber network by means of a linear integer programming method. In a static multi-core optical fiber network, certain service requests are generated, and sufficient spectrum resources are provided for allocation, so that no service blocking occurs. Then, a joint optimization method for the minimum crosstalk and the minimum spectrum slot occupation is established according to an optimization target to be realized and each constraint condition in a service request allocation process, thereby finding an optimal spectrum resource allocation method for all service requests.
