Method, route device and business network for establishing the business connection

Abstract

This invention relates to communication field and discloses one method, router device, business network to establish business connection, which comprises the following steps: determining this point to neighbor point transfer probability according to the linkage biological information concentration of each points and selecting router with maximum probability as this operation to next point router with its neighbor points as this point neighbor points.

Description

Method for establishing service connection, routing device, service network technical field The invention relates to the communication field, in particular to a method for establishing a service connection in network planning, a routing device and a service network. Background technique The core of network planning is to plan the transport network according to the characteristics of the service network. The transport network planning includes network topology planning, routing planning, and survivability planning. Among modern theoretical optimization algorithms, the ant colony algorithm is commonly used, and it can be used to solve the optimal path and so on. Ant colony algorithm is a population-based simulated evolutionary algorithm inspired by the group behavior of real ants in nature, which is a kind of random search algorithm. It was first proposed by Italian scholar M.Dorigo and others. He made full use of the similarity between the process of ant colony searching ...

However, in this method, in the process of establishing a connection for the business, the interaction between the MPLS / GMPLS control protocol and the routing part is complicated, and the consumption of the control bandwidth is relatively large, especially when some emergencies occur, the demand for the control bandwidth will not be met. cause control channel congestion

In addition, MPLS / GMPLS uses labels to distinguish information such as routing and service levels. Different service levels correspond to different label resources. For each level of service, a global label database in the region is required to query. For large Under the constraints of multiple QoS parameters for a large-scale network, this method requires a large tag database and hardware devices with high-efficiency processing capabilities, and also requires a lot of maintenance overhead

Moreover, since the tag resource database is generally fixed, it is difficult to dynamically divide and control service connections and resource allocation

Each node cannot save the routing structure of the entire network in real time, and it is difficult to implement a distributed hop-by-hop routing mode
