Problems solved by technology

[0004] However, using a greedy algorithm to place regenerators does not consider the overall optimality, and what is made is a local optimal solution in a sense, which may generate redundantly configured regenerators, wasting resources

Abstract

The invention provides a method and a device for determining the placement position of a regenerator. The method for determining the location of the regenerator in the present invention includes: obtaining the shortest path P between any two nodes in the network i ,P i Be the i-th path, i is an integer greater than or equal to 1; obtain the optical signal-to-noise ratio OSNR of all paths; add M paths whose optical signal-to-noise ratio OSNR is less than a preset threshold to the first set, and the M is a positive integer ; Determine the attribute value of each node according to the number of repetitions of the node in the path in the first set; determine the placement position of the regenerator according to the attribute value of the node. The method proposed by the invention effectively utilizes regenerator resources while ensuring signal transmission quality.

Description

technical field [0001] The invention relates to the field of network planning, in particular to a method and a device for determining the placement position of a regenerator. Background technique [0002] The smart grid is the intelligence of the power grid. Compared with the existing power grid, the smart grid shows the remarkable characteristics of high integration of power flow, information flow and business flow. With the expansion of the grid scale and the acceleration of power information construction, the information communication network fully covers all aspects of power generation, transmission, distribution, and power consumption, and is used to collect accurate information in a timely manner and provide continuous and reliable operations for power users. . The information communication network is an important part of the smart grid and the basis for realizing safe, reliable, economical and efficient operation of the grid. Therefore, it is necessary to carry out ...
