Abstract
Three links automatically switch networking and are characterized in that only walk a link, other links are standby states, do not walk amount.The presence of link is detected by timing, when a link currently in use is obstructed, takes certain strategy, the functions such as routing table fire wall are automatically switched into other chains roads.The time spent in due to handoff links, is very short, and router is in all kinds of long-term unattended commercial Application environment or can steady operation under various severe natural climate environment.This method can not only undertake business transmission and can share network flow under certain conditions, ensure the patency of network, realize the continual data communication of user.
Description
Technical field
The present invention relates to realizing that a variety of links automatically switch the method for online in router gateway, specifically and linux
Procotol, driving exploitation and application and development under operating system is related.
Background technology
With popularizing for personal mobile phone, computer and industrial aspect communication equipment, demand of the people to network is more and more,
Requirement to the stability of network simultaneously is also increasingly stringenter, and router will not only adapt to all kinds of long-term unattended commercial Applications
Environment, will also under various severe natural climate environment can steady operation, therefore router gateway is in terms of software and hardware
Upgrading should be constantly updated, towards it is more intelligent, can realize intelligent management develop.In this case, in original router
On the basis of existing function, a kind of method for realizing the automatic switchover online of three links in router gateway is realized.
Invention content
The technical problems to be solved by the invention are to provide realizes that a variety of links automatically switch online in router gateway
Method is realized based on the function that network stabilization is kept under various complex environments.
To reach goal of the invention, the present invention uses the operating mode of two kinds of link switchings.Operating mode one opens three chains
Road is online simultaneously.It is online simultaneously to be not turned on three links for operating mode two.Router is logged in using webpage, it can be to both
Operating mode is configured.Under each operating mode option and installment can be carried out to the network access of three kinds of links again.The present invention
All configuration datas are all stored in router gateway, the reading that router can be easily and fast after re-powering these match
It puts, is reconfigured without login page.
Description of the drawings
Attached drawing described herein is used to provide further understanding of the present invention, and forms the part of the present invention, this hair
Bright illustrative embodiments and their description do not constitute improper limitations of the present invention for explaining the present invention.Fig. 1 is the present invention
The flow diagram of method.
Specific embodiment
It is wired that three links include 1. WAN（The automatic acquisition modes of static IP/DHCP）, 2. 3G/4G link 1,3. 3G/4G
link 2。
It is online simultaneously to open three links for operating mode one.Implementation method is as follows：
After router powers on booting, default route is communicated using 1. link, i.e., all data all by 1. link, while also open
With two other link, only two other link is in standby states.Each link is ensured after can networking, and is enabled
The address of on-line checking, at regular intervals some server of ping（The server does not forbid the test of ping functions）, use
After this method detects that link disconnects, chain is switched over according to certain Policy Updates routing table and relevant fire wall
Road, specific switching law are as described below：
1. after if 1. link disconnects, router automatically switches to 2. link；1. if link-recovery, 1. router automatically switches back into
Link；
2. if 1. link does not restore, after 2. link disconnects, router automatically switches to 3. link；1. if link-recovery,
Router automatically switches back into 1. link；
If 3. 1. link not restore and 2. link-recovery, router automatically switch back into 2. link；If 1. link, 2. link are all
Do not restore, be switched to 3. link；
4. if three links all disconnect, router can attempt connection 1. link, 2. link, 3. link successively, and so cycle connects
It connects, until there is a link-recovery to establish connection.This method is advantageous in that, once detect that link currently in use occurs
After failure, the chain road of standby states can be quickly switched into.
Operating mode two, be not turned on three links simultaneously it is online, implementation method is as follows：
After router powers on booting, default route all passes through 1. link, two other using 1. link, i.e., the communication of all data
Link remains static.1. link is ensured after can networking, on-line checking is enabled, at regular intervals some service of ping
The address of device（The server does not forbid the test of ping functions）, after detecting that link disconnects in this way, closing should
The on-line checking function of link starts to carry out initial work to another link（Such as to wireless module send AT instruct into
One sequence of row is configured）Start another link.Another link is according to certain Policy Updates routing table and relevant fire prevention
Wall switches over link, so recycles.Specific switching law is as described below：
1. after 1. link disconnects, router automatically switches to 2. link；
2. after 2. link disconnects, router automatically switches to 3. link（No matter at this time 1. link either with or without recovery）；
3. after 3. link disconnects, router automatically switches to 1. link；If 1. link does not have recovery and 2. link-recovery also at this time
, then it is to automatically switch to 2. link.
The mode whether detection link disconnects has so several：
1. by sending icmp packet（Use ping or tracerouter）；
2. it is detected by sending TCP half-open connections to the timing of some port；
3. in the case of for wireless networking, can also signal strength be judged by timing, trigger handover mechanism.
The preferred embodiment of the present invention has shown and described in above description, as previously described, it should be understood that the present invention is not office
Be limited to form disclosed herein, be not to be taken as the exclusion to other embodiment, and available for various other combinations, modification and
Environment, and can be changed in the scope of the invention is set forth herein by the above teachings or related fields of technology or knowledge
It is dynamic.And changes and modifications made by those skilled in the art do not depart from the spirit and scope of the present invention, then it all should be appended by the present invention
In scope of the claims.
