Method, device, and computer-readable storage medium for determining network topology structure

Abstract

The invention discloses a network topology determination method, which includes: using the basic information of the optical cable network to initialize the basic service information to obtain standard service information satisfying predetermined rules; determining the network nodes in the standard service information through the SRLG network, and each The capacity of the paragraphs between network nodes generates the basic network topology; performs fault simulation on the basic network topology to generate the final network topology. It can be seen that in this solution, based on the basic information of the business and the basic information of the underlying optical cable, the low-redundancy WDM / OTN network planning and design against a single link failure can be automatically carried out, and the required network topology can be automatically constructed, and the network The capacity required by each segment link in the topology structure is intelligently given a network construction scheme; this scheme also discloses a network topology determination device, equipment and computer-readable storage medium, which can also achieve the above technical effects.

Description

technical field [0001] The present invention relates to the technical field of network planning, and more specifically, relates to a method, device, equipment and computer-readable storage medium for determining a network topology structure. Background technique [0002] At present, as the scale of WDM / OTN and other networks becomes larger and larger, the network structure evolves to a mesh network, and the calculation of fault resistance becomes more complicated, resulting in too complicated network planning and design, which exceeds the computing power of the human brain. In traditional manual network planning and design, it is first necessary to manually design the network topology based on conditions such as services and optical cables, then manually arrange service routes, calculate link capacity, estimate outage redundant resources according to a fixed ratio, and finally obtain a network construction plan. [0003] However, with the deepening of informatization and the...

Problems solved by technology

[0003] However, with the deepening of informatization and the rapid growth of the network scale, there are many difficulties in manual planning and design: gradually evolving into a mesh network, its complexity and scale exceed the computing power of the human brain, and low fault interruption redundancy cannot be realized. In general, manual planning Strong subjectivity, the results vary from person to person, the amount of calculation changes greatly, the adjustment is difficult, the cycle is long, and the efficiency is low
