Broadband routers are popular in SMEs
Today, Xiaoku received a letter from a warm reader. The full text is as follows:
Xiaoku:
I am a computer engineer of Taiwan-funded enterprises. Our company has more than two hundred computers. We have used broadband routers to share online, just with the company's development, the number of online Internet is increasing, there is currently nearly 100, but I I found that our original router can only manage 50 computers, and some are some unstable, I want to ask what you have in 2000, you can manage the broadband router for 200 computers, and please tell me if you want Manage this multi-quantity computer Internet, what is required for Flash, and RAM, if they are 1 MB and 4 MB, can it meet?
I hope to get your reply, thank you !!
From this letter, we can at least get this information: broadband routers have become more common to be commercially available. Many famous large companies have now applied broadband routers in branches across the country, such as Shenzhen Airlines. The broadband router is not only higher than cost performance, but also access to ADSL dynamic dial lines, which can easily set up VPN (virtual private network) channels to realize the national interconnection of the organization network, so that branch institutions can use dynamic IP access, Enjoy high-speed proprietary channels and company headquarters networks, and external branches can run financial system software, settlement system software, and video office automation system software conferencing systems, while ensuring that data can be safely transmitted on public online. This advantage is obvious, that is, the enterprise saves the high communication fees necessary for the application DDN line necessary to pay for the fixed IP. Even if there is no network, independent small and medium-sized enterprises use broadband routers to access dial-up ADSL and have dynamic IP broadband access is also a great advantage. It also does not need to apply for a special line and have a higher speed sharing Internet, and Using this dynamic public network IP to set up a network application that only public IP can do with a public network IP.
Important hardware indicators for enterprise broadband routers
Next we will further explore the problem proposed by this computer engineer. Obviously his company has already recognized the benefits of broadband routers and has been deployed from the broadband router shared Internet access, just with the expansion of the company, the original broadband router can not adapt to the needs of enterprise network expansion, now he needs a A more powerful broadband router to achieve 200 computers sharing Internet access. There is also the implementation of such demand, what is the requirements for the performance parameters of broadband router?
This is the return of the broadband router for enterprise applications, which performance adapts to the needs of enterprise-class applications, this is an important performance indicator of a broadband router? For enterprise-class applications, first, you can see if this broadband router can be competent to share the Internet, which is the problem of data throughput. The throughput is a hardware performance indicator of a broadband router, and the cardiac portion of the broadband router will affect the value of the throughput. In fact, the CPU is also the most expensive part in a low price wideband router. The CPU of the broadband router is generally based on the product of each chip manufacturer of X86, ARM7, ARM9, and MIPS. The low-end broadband router is only 30MHz, and the system memory is only 4 MB. Such broadband routers are suitable for ordinary families and SOHO users. ; The processor speed of the medium-high-end broadband router can reach 100 MHz, at least 8 MB of memory, suitable for Internet cafes, SME users, and large enterprises. We can regard the broadband router as a very special computer. Since it is a computer, of course, the higher the CPU speed, the greater the system memory, the better. According to relevant media reports, NetGenesisuperopt developed by Japan's Social Studies may be the highest-wide product throughput, which is equipped with a CPU with a working frequency of 240MHz, with FTP measurement throughput of 94 Mbit / sec. At present, the CPU of the international popular broadband router is based on the ARM kernel and the chip developed by various chip manufacturers. Among them, the domestic common products are more ARM7. Its highest network throughput can reach 20MMBIT / second; and ARM9 CPU Network throughput is between 30m ~ 65Mbit / second, so for enterprise-class applications, consider the broadband router capable of supporting the ARM9 kernel-based CPU capable of supporting higher bandwidth and more users. Because ARM7 is generally only several trillion processing speeds, it is no longer able to adapt to the need for more and more host sharing Internet access needs and the need for the extension of the network, and the speed of ARM9 is 100MHz-233MHz. We should understand that the second important hardware of the broadband router is system memory, the bigger the better, which is generally at least 8M or more. We should first examine its CPU processing speed and its system memory, which determines the hardware performance of broadband routers as a whole. Some readers may be confused: So what? Flash is equivalent to the hard drive of this special computer, mainly used to store the operating system and configuration programs of the wideband router, generally 1M is enough because the operating system and some functional program of the broadband router are not very large. A high cost-effective enterprise broadband router
Next, we will recommend a broadband router that fully adapt to his needs, which is Vigor2104 produced by Taiwan's Juyi Technology Co., Ltd. (see Figure 1). This is an ideal solution that adapts to large enterprise branches, small and medium-sized enterprises and large Internet cafes. Vigor2104 is a high-performance medium and high-end broadband router configured high-speed embedded CPU ARM9. It has reached 168MHz. It shows that this broadband router is currently a relatively high frequency of CPU, which is currently a small number of visible in the domestic market. Assembling the broadband router of the ARM9 CPU, it can achieve high-speed stable communication between LAN and WAN, and will not be able to form a bottleneck accessible in the broadband router. It should be able to run well in the networked environment with more user hosts. . Its hardware interface and device functions are as follows:
Quote: 2300 yuan Shanghai Huakai Technology Development Co., Ltd. Beijing Office (010) 82865131HTTP: //www.it168.com/cdealer/files/cdealer_info.asp? Cdealer_code = 4721 & ctype_code = 0409 & clRAND_CODE = 1419
(1) The hardware interface contains a 10 / 100m basetx wide area network port; four 10 / 100m Basetx exchange ports. The supported WAN protocol contains PPPoE (ADSL dial), DHCP (dynamic main resolution protocol), PPTP (VPN point-to-point tunnel protocol), static IP. (2) Supported NAT features include Multi-Nat (can build multi-group virtual server and real IP), DMZ (non-military zone), port redirection, open port, DDNS (dynamic domain name analysis), Internet application penetration ( VPN, VoIP, NetMeeting MSN Messager, ICQ, Quake.
(3) Firewall features include: access control list, IP-based package filtering, case package check, refusal service attack protection.
(4) Supported IP routing protocols include: RIP V2 dynamic routing protocols and static routes.
(5) Network management functions include: Web-based configuration human-computer interface programs, remote Telnet login, TFTP, or FTP mode system software upgrade, built-in diagnostics, quick configuration wizard, system log monitoring.
These perfect features are ideal for large-scale enterprise branches to use it to do VPN, perform virtual private line network communications with headquarters through the Internet, to achieve business networking with headquarters, this app is also an increasingly popular organ network solution, Big companies have a very high economy; it is also very suitable for independent SMEs to use it as a low-cost and high-quality demand for enterprise local area network security access to the Internet. The "Advanced Settings" of Vigor2104 is worth mentioning because there are some kind of people here. These applications include: (1) NAT settings; (2) dynamic domain name setting; (3) IP filtering and firewall settings. NAT has two functions: First, it can resolve the IP of the user's internal local area network to the only single public network IP application from the ISP application, so that the internal network host shares this IP Internet; I can play a safe role, Prevent the hacker from the Internet from attacking the intranet. Vigor2104's NAT can do three major tasks: First, the port redirect, it can specify an internal network host to use a well-known port to set up a Web, FTP and other servers, and users can access on the Internet; the second is to set up a bureau network In the non-military host, when we need to make a video conference, or when you set a game server, you can specify a particular host in a non-military zone to achieve these functions; the third is open port, we open some of the designated host for the LAN Special ports, this is because some applications use it for "communication." Since most broadband users in China can only get dynamic public IPs from ISP, the public IP is constantly changing, and the traditional way DNS cannot support dynamic IP. Therefore, we must implement the above Web, FTP service, we can only apply for dynamic domain names from companies that provide dynamic domain resolution services (such as domain technology http://www.oray.net/), the domain names of these applications, The account is set in Vigor2104, allowing the Internet to access our website at any time through this domain name. Vigor2104 has two types of filtration: call filtering and data filtering, we generally use the second. It can set 12 filters, each filter can set 7 filtering rules, which allows the IP data of the Vigor2104 broadband router to allow pass or discarded operations in accordance with the set rules. Vigor2104 has a more prominent feature that it is very easy to install and set up. Because the installation has been designed and easy, ordinary users can install themselves without a special network engineer to install your Vigor2104 router. The general settings can easily complete the most basic Internet access settings through the Quick Configuration Wizard, so that the network is connected. Other advanced settings and network management for users special applications are also based on the web-visual interface. As long as you have knowledge of related networks, you can make it easy to configure. Therefore, the human-machine interface configuration program of Vigor2104 is very human, which can reduce the cost of management networks for traditional companies that do not belong to the information industry.
summary:
Vigor2104 is a high-performance and fully fully equipped broadband router, and Juyi Technology has positioned it as branches and small and medium-sized enterprises for large-scale enterprise users. It can also be applied to large-scale Internet cafes and other high-density host sharing Internet environments. The market is one of the large number of products of the broadband router for enterprise applications, has a superior performance price ratio.
