By-pass combination system and business processing method based on said system

Abstract

This invention discloses one side path combination system, which comprises one communication process device and more than one physical linkage, wherein, any one device is connected to any one physical path through physical side path interface unit; any physical linkage has one side path interface unit at non-side path status and communication process device to realize synchronous business information. This invention also comprises more than one communication process device and one physical linkage.

Description

technical field [0001] The invention relates to a bypass combination system and a service processing method based on the bypass combination system, in particular to a bypass combination system based on equipment serial connection and a service processing method based on the system, and belongs to the field of communication technology. Background technique [0002] In a communication system, communication processing devices are usually serially connected to physical links, which can be called serial devices, and perform functions such as attack defense, service filtering, and address translation. As shown in FIG. 1 , the router and the local area network (Local Area Network, LAN) switch shown in the figure are just examples for the convenience of illustration. In actual communication, the devices on both sides can be any type of communication devices. [0003] It can be seen from Figure 1 that due to the serial connection of communication processing equipment, there is often ...

Problems solved by technology

[0007] The above-mentioned technical solution to overcome the single-point failure of series-connected equipment by bypassing the equipment itself cannot overcome the following defects:

[0008] First, when bypassing, the functions of serially connected devices will be lost, which will lead to the inability to provide some communication network functions; for example, if the anti-virus device is bypassed, the entire system will be exposed to virus threats;

[0009] Second, for the series connection equipment that provides necessary functions for communication, when the equipment is bypassed, the communication cannot continue at all; for example, when the equipment is bypassed, the entire The communication link is also paralyzed, which is equivalent to the state where the single point of failure problem has not been dealt with

[0013] To sum up, no matter the equipment bypass scheme or the master-slave backup scheme, there are many defects in solving the problem of single point of failure of serially connected equipment. At present, there is no technical solution to solve the above defects at the same time.
