We have more than familiar with the WAN application.Especially in Internet cafes, broadband access has become more than a necessary business tool.Therefore, in addition to the router Internet cafes Internet cafes with a variety of special features particular, multi-WAN and WAN-related features and multi-router to become the top priority of Internet cafes.
Multi-WAN Internet cafes, broadband access may be from different types and quantities: there is a Telecom, a China Netcom typical "number one dual-network" approach; there is a Netcom, a CRC atypical "one bar dual-network"; there are twoArticle Telecom ADSL (or CNC) of the "bandwidth pool"; there are three or more broadband, "a bar on multiple networks."..
It should be noted that a number of different WAN access mode, select the router's functions must be different.
If you did not notice the function and application of multi-WAN match, then it may cause the game card, slower troubled Worse spend millions more than updated WAN routing, the multi-WAN selected the wrong function, at the expense of bandwidthefficiency did not play a double role in the bandwidth, but you have been kept in the dark.There are a number of important functions, is essential for long-term maintenance of Internet cafes.
This article will briefly introduce some multi-WAN applications, broadband routing function should choose what kind of match.At the same time, from the installation and maintenance point of view, multi-WAN routing features further, to provide you with what kind of help.
First, the typical "number one dual-network" approach
A Telecom, China Netcom is one of the most common multi-WAN access.In this way, the various broadband routing policy routing database as set up, which is collected Telecom and China Netcom's IP address, the so-called run telecom Telecom, Netcom, Netcom run, almost all meet the requirements of application environments.
But "everyone will become magic, clever high and low."In this way, we should give more consideration to the installation and maintenance problems.The question is, "a bar dual-network" strategy is the current version of the routing database, a few days, Telecom, China Netcom IP changed, and game manufacturers to install a new server, this time, your "number one dual-network" How do I update?Be updated?
Download the document, manually update, restart the routing?Neither of these maintenance time, and very tedious, but also may delay the operation, which is annoying long-term maintenance.A better way?
Advanced approach is the "number one automatic dual-network" function, with it, you do not have to worry about Telecom, China Netcom, and game manufacturers change, causing your operation passive.It can consist of manufacturers around the clock to search for IP addresses statistics and changes in the network upgrade automatically use the broadband router, update the policy routing database.You knew, your router has been upgraded.This is welcomed to the route's first "automatic number one multi-network" function, part of the important content.
Therefore, experts recommend: the typical "one bar dual-network" approach to focus on fully automatic update feature, choose a "number one automatic dual-network" function of the broadband router.
Second, the typical "one-bar dual-network" approach
A Telecom (or CNC), a CRC (or Mobile, China Unicom, education) is another kind of "dual-network of a bar."The second because it is not the most mainstream broadband Telecom, China Netcom, one of it in the policy routing database to identify and IP requires some special operations.
First is to identify, fully capable of advanced broadband router identified, whether you're plugged into the WAN port which position.Meanwhile, the second of broadband should be against the Telecom, China Netcom which direction, confirmation and who closely, that is able to select and Telecom, China Netcom's collusion relationship.This feature is called "a multi-network automatically recognize it."
Important is automatically selected documents, automatic update feature.Because of this approach is not a typical application, the combination of a variety of carriers much effort you want to bother you to the vendor database to be discussed in future long-term upgrade and maintenance process, the human factor too many things to worry about.
Welcoming the "Automatic number one multi-network" to identify up to 6 or more carriers, and policy routing database that contains all of the IP address of content, including access portfolio, do not choose to upgrade the type of document.Welcoming to the broadband router, network upgrade process is completely automated intelligent, automatic.
Therefore, experts recommend: Atypical "a bar dual-network" approach to focus on the automatic recognition of broadband, will be able to automatic updates to identify and not human intervention.Therefore, to choose a "number one automatic multi-network" function of the broadband router.
Third, the same operator's "bandwidth pool" approach
All access to telecommunications, or access to all Netcom, this multi-WAN is the "bandwidth aggregation."In the broadband router, you should select the appropriate "bandwidth pool" work mode.
In this mode, broadband routing applications, the biggest obstacle is the "binding capacity" problem, BNB, QQ, MSN, online banking and other businesses are not allowed to run through two broadband lines.BNB in particular and so on, connecting the port changes each time, not bound to a fixed line.If the "Bandwidth aggregation" approach, not support the "binding capacity", BNB, QQ, etc. does not work.
Does not support the "binding capacity" of the router to work in this way is absolutely impossible.But some do not "bind as" function in the normal use of the router literally, this is why?
Deceive these routers using the original method.You should pay attention to whether it's setting in a multi-WAN requirements, such as "IP load balancing" option.If so, it uses the method of avoiding problems is hard to separate all of your users, each user can only access in a line, not stuck BNB, QQ can not afford, and looks normal.However, this effect is that you use the bandwidth to be greatly scaled down, the bandwidth can not be reused.From the multi-threaded download test results, the bandwidth efficiency dropped more than 40%.Moreover, multi-WAN routing into a combination of two single WAN, WAN investments and more things become meaningless.
Also note that some routers have design flaws, can not support the same central office access, that is, the two can not use the same broadband telecommunications gateway.This router is not optional.
Therefore, experts recommend: operators in the same "bandwidth pool" mode, we must choose to support "as binding" function of the broadband router.So that your WAN bandwidth efficiency and more investment will not be discounted.
Fourth, the two telecom, a line of other "hybrid access" means
Over the same two operators, in addition to one other line access network, multi-WAN applications is more complicated situation.This application is currently limited, but with the cafe's business development, a broadband connection may be more than you expect in the plan.So now choose a route, you should take precautions by.
In this case, it is necessary to solve the "number one multi-network" problem, but also open the "bandwidth aggregation."This application generally occurs in more than a 3 broadband router WAN port.This application requires broadband routing with "fourth-generation multi-WAN technology" capability.
Fourth-generation technology can achieve the multi-WAN load balancing, policy routing based on the dynamic identification of different businesses, auto-complete as binding, while achieving more advanced load balancing, multi-line transmission of video streams, VPN traffic, VoIP voice streamtechniques.This is also welcomed to the first one of multiple WAN technologies.
Therefore, the experts recommended: three or more broadband access, or set aside for future expansion of broadband WAN port of the Internet cafes, broadband router should check in advance whether to support the "fourth-generation multi-WAN technology" to avoid "mixed access" approach work, resulting in the loss of equipment does not apply.
Several cafes in the above described common access mode, multi-WAN routing functionality options.It can be seen, application and function if the error to "arbitrarily arranged" and would cause considerable damage.Automatic identification of broadband lines, automatic number one multi-network, the network routing address database automatically upgrade further advanced features such as the installation and maintenance management is very important.
Welcoming the mainland to the routing technology, the first advocate of multi-WAN, WAN routing is now the mainstream of Internet cafes and more brands.WAN in the cafes and more applications, welcomes the rich to the routing function to cope with various access methods to cope.In the "binding capacity", "number one automatic multi-network", "automatic upgrade", "fourth-generation multi-WAN", etc., at present, welcomed the many cafes to firmly occupy the irreplaceable WAN technology leadership, wonapproval of a large number of users, which is their continuous technological innovation and service concepts are closely related.
