Problems solved by technology

However, in the calculation process, the reliability of the resource link itself is not judged. As a result, it is often impossible to select a more reliable path as the bearer when there are multiple reachable paths and all of them can meet the bandwidth priority. Then, in the subsequent management and There will be more investment and support in maintenance

Embodiment Construction

[0050] The present invention will be further described below in conjunction with specific examples and accompanying drawings.

[0051] This method relies on the input of pre-information, that is, the source and destination points of the user's desired path and the information of nodes that must pass through or not pass through. figure 1 It is a structural schematic diagram of the system of the present invention, which includes the following modules:

[0052] The SPF routing calculation module is used to calculate the shortest path search algorithm for the existing routing situation and user input, using the greedy algorithm of the single-source shortest path, taking the difference between QoS and bandwidth as the weight, and using a binary heap for optimization. And the calculation result is used as the return value; the calculation results are divided into three categories: the first category is that there is no satisfactory path between the source and destination points, and...

Abstract

The invention provides a system and a method for strengthening reliability of routing computation by using a time series prediction model all the time. The system comprises an SPF (storage protect feature) routing computation module, a model pre-processing module, a history alarm information database, a model computation module and an analytic statistics module. Alarming related data bearing links are stably sampled by using a time series prediction model algorithm, finally predicted data are generally evaluated by recognizing the corresponding prediction model, so that routing required by a user can be acquired by using an SPF algorithm, reliable links computed by using the model are recommended to the user on the basis of equal routing, risks on maintenance are greatly reduced, availability of bandwidth and balance of network load can be realized, reliable route selection is recommended on the premise that the original bandwidth path can be met, and extra expense for later operation and maintenance is reduced.

Description

technical field [0001] The invention relates to the communication field, in particular to performing reliability prediction and analysis on the result of service routing calculation in network management and northbound systems. Background technique [0002] Routing calculation is already a very common and important technology in the current network management system. With the development of PTN network, automatic routing calculation has become an essential and important function for service creation in network management software. Especially in the support of the northbound interface, the current mainstream TMF814 specification that uses CORBA as the technical middleware increasingly emphasizes the importance of service configuration. The createSNC function in the MultiLayerSubnetwork submodule is what the upper-layer network management needs to automatically calculate and issue routes. Actual demand. [0003] At present, the routing calculation of many network management s...
