Covering network system and route selecting method

Abstract

The invention discloses an overlay network routing method and an overlay network system, basing on topology aware. The overlay network routing method includes that step one, obtaining the default path from a communication terminal node to a target terminal node; step two, obtaining the overlay network path of the communication terminal node to the target terminal node through overlay network neighbor nodes; step three, computing the number of the overlapped nodes between the default path and the overlay network path; step four, the invention can effectively reduce the correlativity of the created overlay network path and the default path, better improve the transmission of the network and the fault-tolerance capacity and guarantee the stability of communication by the path switching or path diversity transmission technology even under the conditions of network faults or unstable performance.

Description

An overlay network system and routing selection method technical field The invention relates to the Internet, in particular to a topology-aware overlay network route selection method and an overlay network system. Background technique With the rapid expansion of the scale of the Internet, in order to meet the growing needs of traditional applications and emerging services, the Internet is facing many problems that need to be solved urgently, and its own structure is also undergoing continuous evolution and development. Border Gateway Protocol (Border Gateway Protocol, BGP) is the core routing protocol of the traditional Internet (Internet). Since it was revised in 1995, it has not been greatly modified so far. However, due to the rapid expansion of the Internet, the scale of the inter-domain routing system is also expanding, the network topology becomes denser, and the interconnection becomes more and more complex. The problems of poor redundancy and low efficiency have ...
