Six key issues for proper selection of multi-wan routing

At present, many enterprise networks choose multiple WAN applications, and there are more and more varieties of multiple WAN routers in the market. However, as an emerging product, the user's understanding of the technical level is not deep enough to have a lot of misunderstanding. It can be said that most users have more or less the purchase error.

In general, in the face of the purchase of multiple WAN routers, many business friends just focus on the "more" word on multiple wan, but there are many kinds of WAN routes, some even completely different things. There are also many joints in the functional configuration of multiple WAN routing. Just look at the package listed on a large pile of functions, and do not know the meaning of this, the loss in the second, the important thing is not to play a role, will miss the big things.

The right choice for a multiple WAN router should focus on the following key issues:

One, clear multiple WAN routing type, know what nature of the product to buy:

Multi-Wan routing according to the application can be divided into a number of major categories, the market is often the main 3 categories: one is "a bar of multiple network" type, the second is "bandwidth convergence" type, the third is "IP equalization" type.

"One bar Multi-net" type multi-wan router is mainly used for broadband access of different operators, such as Netcom, a telecom or an education network. It is based on the destination IP Wan Port selection of the multi-Wan application type, it is mainly to solve the domestic netcom, telecommunications and other access to the bottleneck of the exchange. Generally noted that "Internet cafes dedicated" multiple WANs belong to this kind of products, in the education network and some specific occasions also have applications.

"Bandwidth pooling" multi-wan routers are mainly used to increase the bandwidth of network access. One more broadband, one more bandwidth, fast one times faster, this is the "bandwidth convergence" function. It is based on the number of sessions per PC, by automatically assigning them to more idle lines, the "IP-balanced" multi-wan router is equivalent to 2 single WAN routes, with the exception of the same gateway, the same set of management policies, and the less efficient use of multiple WAN connectivity effects. This router is called a "fake multiple wan." At present this kind of route already rarely exists alone, but this function also exists some route configuration, as long as the user does not choose the "IP equalization" This function, is equivalent to bought "IP equalization" type router. This is also a special topic to be addressed below.

In addition to the third "fake multiple Wan", the first two routes have their specific uses, the effect is very different, is not universal. There are exceptions, however, that a fourth-generation multi-WAN technology is adopted by the new router, which can combine the two organically by automatically identifying the broadband type. This is more suitable for both "a bar of multiple nets" also need "bandwidth convergence" occasions, such as 2 Telecom, an education network access environment.

In short, users want to understand that multiple WAN routing is different, the first choice must be based on their own use of the environment and purpose, to ensure that the right product.

Second, the selection of the appropriate number of machine indicators, generally twice times, the need to manage the function of greater:

All routers are involved in the purchase of a specific number of machines to ensure that the router can carry a certain scale of network processing load. Generally speaking, the manufacturer propaganda belt machine quantity is the theory with the machine quantity, the actual use will discount. In order to guarantee the use, we usually need to buy twice times the actual number of computers with a router. Otherwise, there are often network problems caused by insufficient processing capacity.

With more and more functions of router management, some protocols and behavior management greatly consume router processing resources. For example, using the router's seal BT, MSN, QQ and other functions will make the router's hardware resources loss of 1-1.5 times times, this also tells us if the router to open the behavior management function, then the theory of the purchase of the router to be the actual number of computer 3-4 times, otherwise the use of the router's behavior management function will be significantly reduced by the speed of the price, no pace of management " Outweigh the gains.
