Embodiment Construction

[0031] The preferred embodiments of the present invention will be described in detail below with reference to the accompanying drawings.

[0032] figure 1 An iterative-based adaptive resource calculation method is given. In the early stage of business planning, it is necessary to analyze the expected cost to meet the specific market demand, and ensure that the network can be controlled and convenient for charging. At the same time, the revision of the initial basic information of the network should be considered to support the requirements. Business selection also needs to consider business prospects, and set network goals and QoS performance goals. When configuring services, the causes of failures need to be isolated, whether they affect the business or not. The criterion for iteration in the network is mainly for the management of service quality, for example, whether the required service level is achieved, whether there is a general problem in the service or product, and...

Abstract

The invention relates to a multi-level joint routing and survivability strategy based on economic factors and belongs to the field of communication networks. The establishment of an economic objectivefunction is researched and planned under the framework of a planning and optimization model, and a multi-level joint routing algorithm considering the economic factors is adopted to provide a route calculation function for network planning, and at the same time, an optimization protection and recovery strategy based on shared resources is researched. Through analyzing the granularity and the service level of affected service, a recovery strategy is selected, for service with large granularity and a strict recovery time requirement, a corresponding optical layer recovery is adopted, and for service with small granularity and a long recovery time or no time requirement, resources in a shared resource pool are used to take corresponding recovery measures at an IP layer. In addition, throughinteraction between the artificial ant processes, a differential routing calculation problem is solved, the generation of a large number of useless solutions is avoided, and the efficiency of route search is improved.

Description

technical field [0001] The invention belongs to the field of communication networks and relates to a multi-layer combined routing and survivability strategy based on economic factors. Background technique [0002] The transport network is currently developing in the direction of wide bandwidth, high speed and multi-service. Especially in recent years, with the rapid increase of Internet users, the requirements for the bandwidth and quality of the transport network are getting higher and higher. At the same time, the network is also changing from a single technology The structure develops toward the coexistence of multiple technologies, and the structure becomes more complex. The problem of routing planning optimization and management in such a high-speed, multi-level transmission network is more prominent and urgent to be solved. Since the transmission network is a huge and complex network, in order to facilitate the design and management of the network, it is necessary to ...
