Detailed Explanation of Six Key Parameters of Routers

With the gradual popularization of broadband networks, routers have been increasingly widely used, resulting in the development of the broadband routing market. Various manufacturers have launched router products with different functions and numerous names, making it difficult for most consumers who want to purchase routers but lack basic technology to choose. Therefore, today we will talk about several major parameters of routers. If you are not familiar with routers, Then select the router according to these parameters.

1. Number of WAN ports

Multi WAN port routers should first have strong performance and have more bandwidth compared to the outlet. If their processing capacity is limited, multi WAN ports are purely a decoration. There are different brands of multi WAN port routers on the market now, with varying performance. When choosing, it is important to first consider the performance. If it is an ARM7 processor with a main frequency less than 100M, the performance is basically not enough to make multiple WAN ports. 4G Cat4 Cpe

2. Number of machines

The number of machines is very intuitive and easy to understand, but it is only an estimated and empirical value. When referring to this data, everyone must pay attention to the misconceptions mentioned above. At the same time, when assessing the credibility of the data, the credibility and reputation of the manufacturer providing the data should be considered. 4G CAT6 CPE

3. Throughput

Throughput is the throughput of LAN-to-WAN, which should generally be the test data obtained when NAT is turned on and the firewall is turned off. There are two methods, Smartbits testing and Chariot testing, and the results can be very different. According to current hardware capabilities, it is easy for everyone to achieve line speed in Smartbits bulk testing data, just like testing the intelligence of college students, with the question of 1+1=?, Everyone can answer, but there is no comparison. So we need to make an objective evaluation, and the questions should be a bit more difficult. Compare the 64Byte small packet test data, and make a high judgment. Of course, if there is NAT hardware acceleration, turn it off and test again. As for Chariot testing, it should be fair to compare it in the same testing environment and method, with the same number of connections. Moreover, in practical network applications, it is almost impossible to have a single connection, so Chariot testing is best conducted in multiple connections. Generally, 100 pairs of connections can be selected to basically show the clues. In short, a single Throughput data is meaningless. It is important to explain the method used to measure this data in order to be useful. The comparison of mutual performance must be conducted in the same testing environment and method in order to be fair and meaningful. The best way is to watch Smartbits test NAT and enable LAN to WAN Throughput for 64 Byte packets.

4. Flash capacity

Ordinary users don't need to understand how big Flash is at all. They just need to see if the features meet their needs, and at most, it's enough to see if the user interface looks good. 5G CPE

5. Memory capacity

Usually, 1M-4M Bytes are considered small, 8M Bytes are considered moderate, and 16M Bytes or above are considered large. Also, it should be noted that many dealers and even manufacturers only mention how much memory is, so it is important to ask whether it is Byte or Bit. Memory can be measured in Bytes or Bits, and the difference between the two is 8 times the capacity difference (1 Byte=8 Bit)! Generally, uppercase B represents Byte, and lowercase b represents Bit. People with ulterior motives may cheat here, some may not label units, while others may label b as B to deceive others. You can check it out on the website of the chip manufacturer. Some unscrupulous individuals even use polishing chips to fabricate chips on screen printing, so it is important to choose products from honest and trustworthy manufacturers.

6. Processor main frequency

Generally speaking, processors with a main frequency of 100M or less belong to lower main frequencies, those with a main frequency of 100-200M are moderate, and those with a main frequency of 200M or above belong to higher main frequencies. Also, it depends on which kernel the processor is, whether it is 80186, ARM7, ARM9, MIPS, or Intel Xscale? What is the cache capacity? Is it single CPU or multi CPU distributed processing? The 80186 and ARM7 core processors are typical configurations of the first generation broadband routers, with low performance and are no longer used by mainstream manufacturers. ARM9 and MIPS core processors are currently the mainstream. The Intel Xscale architecture is an advanced network processor used in high-end products. A cache capacity of 8K or less is considered small, 16K is common, and 32K or above is considered large. Generally, processors are single CPU, while those using multi CPU distributed processing are advanced processors with high performance. You can also delve deeper into whether ARM9 is a regular 920T/922T/940T or an enhanced 926E/946E/966E, and whether MIPS is 2K, 3K, 4K, or 5K. The performance and structure of different models will vary greatly. If you are interested, you can search online by processor model, and then go to Ruigu Zhilian's website to take a closer look..
