A service-aware routing protection method based on Bayesian classification

Abstract

The invention provides a service awareness route protective method by means of Bayesian classification, and relates to the technical field of optical communications. The service awareness protective method by means of Bayesian classification is proposed to solve the problems that the traditional Bayesian classification algorithm is low in accuracy, a weighting algorithm is not fast and comprehensive in weight judgment, the existing priority level model is unreasonable, the existing priority level model is unidentified in corresponding QoS parameters, and consideration of distinguishing protection is not comprehensive. The importance degree of information defined by the service awareness protective method by means of Bayesian classification can evaluate the importance degree of characteristics effectively, the importance degree of the characteristics is combined with the Bayesian classification algorithm, service priority level can be distinguished accurately, the requirements that services of different priority levels correspond to different QoS parameters are met, and then route is distinguished and protected. Moreover, the wavelength layering topology is adopted, wavelength sources can be used conveniently and fast, and the protective method can be selected from special protection and shared protection. Further, on the condition that the requirements of transmission are met, the number of unoccupied protection paths is minimized, and the utilization rate of network resources is improved.

Description

technical field [0001] The invention relates to the technical field of communication networks, in particular to a routing and protection method considering service awareness in an IPoverWDM network. Background technique [0002] The rapid development of IPoverWDM network has greatly improved the network transmission capacity and solved the problems caused by the rapid growth of IP services such as voice, data, video and multimedia. However, the next-generation network has a development trend of large capacity, intelligence, and high reliability. This requires the network to be able to automatically perceive its type for the business and provide it with a corresponding reliable level of service quality assurance. To this end, a unified combination of targeted service-aware classification and differentiated routing and protection policies is critical. [0003] Business perception classification is the process of learning the rules by perceiving and analyzing the characteristi...

Problems solved by technology

However, this results in low resource utilization, and the determination of available wavelengths before each protection makes the real-time performance not high enough

In short, the accuracy of the traditional naive Bayesian classification algorithm is not high, and the weighting algorithm is too dependent on the empirical threshold or the judgment of the weight is not fast and comprehensive enough, and the existing priority model is unreasonable and does not clearly correspond to the QoS parameters. Differentiated protection considerations Relatively one-sided
