With the popularity of broadband access, broadband router market in the past two years become a new bright spot. Compared with the broadband and narrowband, the most important is a "fast", which is why we in the purchase broadband router, very concerned about the performance of how, it is the popular "fast unhappy." So many people have suggested a range of evidence to prove their own broadband router performance is good, very quickly. But much of the evidence is often one-sided, so you go back and find properties to buy enough time has too late. This article from a professional point of view, analysis of the latest broadband router on a hot issue - with a machine number.
Usually, we introduced by vendors De performance parameters in the table at all OK to see the broadband router to the nominal own Dai 200 Taiwan PC, but when the broadband router as a matter of fact 很多 and Biao Chen's Zhi very different. For this problem, we should be depending on the specific network application should be determined, but is still no clear criteria to measure the actual broadband router can bring Machine in. Because the differences in each network busy, the router load levels vary.
Quantitative evidence of a belt conveyor
Saying: "This router with a machine capacity of 200. "" The maximum allowed with the router machine capacity of 253 units.
Myth: This is not accurate. Different from the peak level of each network, Internet cafes are all buried in the Internet chat, games, and almost all of the data through the router WAN port, so a heavy load. However, if an enterprise network, most people are busy engaged in the design, write reports, to plan, at the same time only a small part of the network in use, and most data are within the flow of the enterprise network, so the router is very light load . In a 200 PC performance enough for the enterprise network router may be connected into the Internet cafe are all with 50 PC fixed. Estimate the average of a network data traffic each PC can not do is accurate. It is like a cafeteria staff to cook, can only eat an average of 42 estimates, the pot enough for 10 people about four kilograms of food, but it is likely that one day we made a movement, an unusually good appetite, a Pot Rice for only 6 individuals to eat, or pandemic flu day we generally poor appetite, come 5 people have enough food to eat. Miners canteen chef to estimate the average person ate 62, and female models estimated canteen chef could only dare to eat an average of one or two. Therefore, a more objective statement should indicate this with a machine capacity is for what type of network, and the number is out in accordance with a typical range of estimates, such as "Internet cafe with a machine capacity from 150 to 250 (typical)" this argument on more responsibility. The second largest amount of machines allowed to say is bluffing, it's not the router's performance based, but most can be assigned DHCP IP address number 254 is lost it myself a 253.
Advanced users: with only an estimate of the number of machines and experience the value, must be combined with the actual situation of the network to look at, or look at testing the performance of accurate data, Smartbits test NAT to open 64 Byte packets of the LAN-to-WAN Throughput is the number of pps (packets per second). If the data from other large manufacturers, the mouth of reputable manufacturers are generally to be relatively stringent, high reliability. If it is from a small factory, the mouth-name manufacturers, the general statement is ambiguous and credibility of the poor.
Machine number two with evidence
Saying: "This router is a dual-WAN port, performance is twice the single WAN port. "" Single WAN port with a volume of 100 machines, machine capacity with dual WAN port 200. "
Wrong: It's a confusing concept. A router hardware and software to determine the basis, its capacity or performance on the set, with the WAN port will not increase or decrease while the number of significant changes. There is a situation: the router processing capacity relative to its WAN port bandwidth of a surplus export, such as a router processing capacity 40M, WAN exit bandwidth of each line 10M, bandwidth, due to the limited export of a single WAN port router can only have 10M of throughput, Dual WAN port router will have 20M of throughput. From this perspective seems to double the network performance, but this is only your network configuration issue is reasonable, router performance is always 40M, did not change too. Conversely, if the router itself is processing only 5M, either single-or dual-WAN port WAN port may only have 5M throughput. For example, a plant could do 10 000 products per day, but only a container truck, daily delivery of 5000 products only, when a cargo truck on the increase is effective. However, if daily production is only 3000, but also with the two cargo trucks, on no effect, create more costs.
Advanced users: now the market has a number of different brands of multi-WAN port router sales, but performance varies greatly. WAN port of a router to do more, we must first set up the router itself, the premise of performance to be strong enough, relative to the export of surplus bandwidth, router processing ability, if their capacity is limited, multi-WAN port on a purely decoration. Members in the choice of many WAN port router, be sure to carefully examine its performance, it is for your reference: If the router is used, or is performance ARM7 processor core, clocked less than 100M, the performance can be determined basically not do more WAN port.
Through the above analysis, readers want to buy a broadband router must clear now! Making choices broadband router products, should consider their specific application to choose. But for home users, the general view that broadband router is fully qualified to provide higher transmission performance.
