| Our modern life is more and more depending on the communication network, making the network transmit all kinds of operations, not localize voice or less data, but a mass of multimedia audio frequency and video frequency data, which results in that more operations converge less network node.when these nodes or communication links appear malfunction and not resume in a little time, the ponderance of the result is not imaginable.Because of network malfunction not be avoided, network malfunctions which are fastly detected, recognized, resumed, becomes the key factor of improving reliability of the network .Self-healing is that operations influenced automatically resume from broken down components in a little time not depending on man intervening, when malfunctions appearing in communication network. The basic theory is that making the network have the ability of discovering substituted path and newly establishing new communication.This thesis brings forward a kind of solve scheme of improving the reliability and usability of the network , mainly based on the topology structure and present problems of present military auto-directing network, designing and implementing a kind of self-healing system of LAN access point.The system can make El link of LAN access point have a redundant hot-backup link, which has the ability of links and devices's malfunction auto detected, oriented, handled between access point of El link and local router .This thesis firstly analyses and introduces present self-healing technologies of the network, secondly introducing the topology structure of the present military auto-directing network, Detailedly expounding total designing idea , system function, working process. Self-Healing system includes hardware and software two parts, in the part of hardware, mainly expounding hardware's function, diagram of modules, communication protocol with software. The software main expounds the system structure of software, the function of subsystem, working... |
