ASUS Server to build professional dual-line router solution

We usually have more contact with "hard" routes in our daily lives. The so-called hard routing is a special application of hardware devices, including processors, power supply, embedded software, to provide the configured router function.

"Soft" routing is relative to "hard" routing, refers to the use of professional servers, with the free Linux/unix platform or professional Windows platform set up.

The advantages of "soft" routing are many: first, the application of a large flexibility, relying on software to achieve unlimited management applications, very cost-effective and easy to expand; Secondly, with the characteristics of stability, reliability, which is the most valued by users, at the same time, benefiting from the operation of Open source, currently based on the UNIX platform, such as RouterOS, M0n0wall, SmoothWall, IPCop, Coyotelinux and other free firewall software, making "soft" routing easy to achieve professional software firewall functions, in addition, "soft" route cost-effective, Thousands of yuan to achieve dual Gigabit line driven 600 client-level configuration, for the shape of the limited funds of the education industry users can be described as suitable.

Below, we take the campus network environment application for example, under the premise of ensuring high performance and high stability, taking into account the Low-cost, to Asus RS100-X5/PI2 as the base hardware platform, to create a dream combination of soft routes.

Soft routing construction solution with balanced performance and cost

Campus network environment as a typical application of the most complex application environment, the demand for routers is also relatively harsh: first, the application of the router's data processing capacity is strong enough to ensure high-speed access to the Internet, and secondly, the stability and reliability of such routers have higher requirements, Not only for a long period of uninterrupted stability, but also requires the router to have strong compatibility, can adapt to different operators of different access services; In addition, in order to ensure the performance of the premise, to have a reasonable price, that is, with excellent performance price ratio.

(1) Platform selection--Green server boutique ASUS RS100-X5

Asus RS100-X5 is an ASUS built server product with only 15 inch rack depth. This "green" as the highlight of the server products are quite excellent, its materials all adopt RoHS-certified Environmental protection materials, and ASUS unique Air-through architecture design is to make Asus RS100-X5 become a set "stability, mute, environmental protection, energy-saving" in one of the green server boutique.

Green Server boutique ASUS RS100-X5

ASUS RS100-X5 can provide multiple core processor collocation, from Low-cost E2000 series dual-core processor to professional Xeon series dual-core processor, users can choose according to demand, in addition, the machine equipped with professional-grade dual gigabit NIC, Can satisfy the user in the special occasion to two lines load balanced and the line backup use demand; In particular, the server front panel uses a dense honeycomb-type heat control, on the ultra-thin asus Mute dvdrom (optional), hard drive lights, power instructions and so on display, Two network working status LEDs and power switches are lined up in the upper right of the panel, allowing the operator to maintain a clear management.

(2) Extended equipment--ide to CF conversion card

In the application of government, SME or campus network, users will inevitably encounter such as the use of the same port hard disk or memory card, and this machine does not configure IDE and memory card interface, so it is necessary to add an interface expansion card.

CF memory card has the characteristics of earthquake resistance, high temperature, long life and so on is not comparable to the ordinary hard drive, so we use CF card to replace the hard disk. With the IDE to CF conversion card, the CF memory card can replace the hard disk as the primary storage device for the server. With this conversion card, the computer system identifies the CF card as a standard hard drive device. If the CF memory card has enough capacity (the current largest CF memory card capacity is 12GB), the Windows XP operating system can even be loaded into a CF memory card to run.

Product specification

--Standard parent 40P IDE interface

--Standard CF card interface

--4P Power Interface

--led read and save busy instructions

--Size: mm x

(3) Software configuration--rich resources management simple

The most core technology in router technology is software technology, which can realize routing protocol function, look-up table forwarding function and management maintenance, etc., we can even get the source of routing protocol and data forwarding in the free sharing software.

In the table below, the editor lists several Web sites where you can download routing software, where you can download software for soft route loading.

Customer Benefits

Through the above hardware and software configuration, the final construction of soft routing can be implemented beyond imagination. Equipped with a good soft routing Goucoin led by (Router), professional firewall, QoS bandwidth flow management, multiple line load balancing, VPN, Internet behavior Management, and many other functions.

Finally, to remind readers that users in the purchase of routers to fully integrate their own network environment and investment plans, for the limited funds of users, server-based platform to build soft routes is really a good alternative. However, due to the limitations of the computer, soft routing can only use Ethernet card, so basically limited to the connection between the Ethernet network, if the network is large enough to divide the subnet, then the efficiency of the soft routing is obviously unable to meet the high-speed communication between the network.
