Problems solved by technology

[0004] The purpose of the present invention is to provide a reliable intra-domain centralized routing control method for the problems of inconsistency in distributed intra-domain routing, easy formation of routing loops, and weak management and control capabilities in existing tactical communication networks. When convergence fails or routing loops exist, it can provide effective service transmission routes for upper-layer applications, and support network managers to intuitively control the real-time status of the network

Abstract

The invention discloses a method for performing centralized routing control in a distributed communication network. A centralized routing control module is added in route switching equipment to become double-mode route switching equipment capable of working in a distributed routing mode and a centralized routing mode; the two routing modes are mutually exclusive; and mode switching is controlled by routing control management equipment. The method for performing centralized routing control in the distributed communication network has the beneficial technical effects that soft switching of the communication network between the distributed routing mode and the centralized routing mode is supported. When distributed routing of the communication network cannot converge or a routing loop exists, the communication network can be directly switched to the centralized routing mode, thereby effectively eliminating the routing loop. The centralized routing is adopted to provide valid loop-free routing for service transmission, so that the sensitivity of the network to link disturbance is lowered, and network management personnel can directly grasp a real-time network state.

Description

technical field [0001] The invention relates to the technical field of communication networks, in particular to a method for performing centralized routing control in a distributed communication network. Background technique [0002] The current tactical communication network is based on the IP technology system and uses distributed routing protocols such as OSPF, EIGRP, and RIP to complete route calculation and data forwarding. When the distributed routing mode is adopted, each node independently calculates its own route, and the routing and switching equipment must not only perform control functions but also transmit service packets, resulting in overloading of the routing and switching equipment. Due to the harsh tactical environment and the poor stability of network communication links, frequent distributed routing calculations often lead to routing inconsistencies, routing loops are easy to form, and the network is in an unstable state for a long time. Reboot the devic...
