Translated fromChinese技术领域technical field
本发明涉及网络通信领域，具体是一种在网络通信中断时进行网络切换系统及方法。The invention relates to the field of network communication, in particular to a system and method for network switching when network communication is interrupted.
背景技术Background technique
网路中断，是指CPU在正常运行程序时，由于内部、外部事件或由程序预先安排的事件，引起CPU中断正在运行的程序，而转到为内部/外部事件或为预先安排的事件服务的程序中去，服务完毕，再返回去执行波暂时中断的程序。Network interruption means that when the CPU is running the program normally, due to internal or external events or events pre-arranged by the program, the CPU interrupts the running program and turns to serve internal/external events or pre-arranged events. Go to the program, the service is completed, and then return to the program where the wave is temporarily interrupted.
网络故障诊断应该实现三方面的目的：确定网络的故障点，恢复网络的正常运行；发现网络规划和配置中欠佳之处，改善和优化网络的性能；观察网络的运行状况，及时预测网络通信质量。网络故障诊断以网络原理、网络配置和网络运行的知识为基础。从故障现象出发，以网络诊断工具为手段获取诊断信息，确定网络故障点，查找问题的根源，排除故障，恢复网络正常运行。Network fault diagnosis should achieve three purposes: to determine the fault point of the network and restore the normal operation of the network; to discover the inadequacies in network planning and configuration, to improve and optimize the performance of the network; to observe the operating status of the network, and to predict the network communication in time quality. Network troubleshooting is based on knowledge of network principles, network configuration, and network operation. Starting from the fault phenomenon, the network diagnostic tool is used as a means to obtain diagnostic information, determine the network fault point, find the root cause of the problem, remove the fault, and restore the normal operation of the network.
网络故障通常有以下几种可能：物理层中物理设备相互连接失败或者硬件及线路本身的问题；数据链路层的网络设备的接口配置问题；网络层网络协议配置或操作错误；传输层的设备性能或通信拥塞问题；上三层CISCOIOS或网络应用程序错误。诊断网络故障的过程应该沿着OSI七层模型从物理层开始向上进行。首先检查物理层，然后检查数据链路层，以此类推，设法确定通信失败的故障点，直到系统通信正常为止。Network failures usually have the following possibilities: failure to connect physical devices to each other in the physical layer or problems with the hardware and the line itself; interface configuration problems of network devices at the data link layer; network protocol configuration or operation errors at the network layer; equipment at the transport layer Performance or communication congestion problems; upper three layers of CISCOIOS or network application errors. The process of diagnosing network faults should follow the OSI seven-layer model from the physical layer upwards. First check the physical layer, then check the data link layer, and so on, try to determine the point of failure of communication, until the system communication is normal.
网络中断的处理方法：建义单独使用网络，部分系统对于网速的要求很高，所以很有可能造成网络延迟的情况，建议避开使用单独的网络，不要共用一个。建义重新拨插一下连接网络硬件：由于硬件的质量问题而导致的现象，就可以通过更换或者是重新连接的方式来解决，一般如果是这种物理原因是比较好解决的，只要拔插一下网线或者更换水晶头，让路由器重新关一下电源等，就可以解决。How to deal with network interruption: Jianyi uses the network alone. Some systems have high requirements for network speed, so it is very likely to cause network delays. It is recommended to avoid using a separate network instead of sharing one. Jianyi Re-plug and connect to the network hardware: The phenomenon caused by the quality of the hardware can be solved by replacing or reconnecting. Generally, if it is this physical reason, it is better to solve it, just plug and unplug it. It can be solved by changing the network cable or replacing the crystal head, and turning off the power of the router again.
目前，通信设备接入网络后，当网速不稳或通信中断时，大多对该网络进行报警，在对网络进行维修后继续连接通信设备，通信设备重新开始数据传输，这样会导致在网络异常时，通信设备数据传输停滞或效率降低，本申请旨在在通信设备通信中断的过程中，自动激活区域内的备份网络，筛选所有备份网络，使通信设备择优连接。At present, after the communication equipment is connected to the network, when the network speed is unstable or the communication is interrupted, the network is mostly alarmed. After the network is repaired, the communication equipment continues to be connected, and the communication equipment restarts data transmission, which will lead to abnormal network conditions. When the data transmission of the communication equipment is stagnant or the efficiency is reduced, the present application aims to automatically activate the backup network in the area during the communication interruption process of the communication equipment, screen all the backup networks, and make the communication equipment connect optimally.
