How to correctly select a Broadband Router

With the development of China's routing industry, it also promotes the wide application of broadband routers. Here we mainly introduce how to correctly select a Broadband Router. in the online world, every Broadband Router is like a post office, classify and integrate the information on the network, and transmit them to the destination according to the address.

Broadband routers have become one of our essential network devices. They play an extremely important role in home broadband sharing, office network establishment, and various broadband network applications. So how should we choose a suitable Broadband Router? This article will focus on the performance of the bandwidth router CPU, to provide you with a practical procurement advice. As an interface device for Internet cafes, A Broadband Router plays a vital role in the entire architecture. In terms of structure, a Broadband Router is a dedicated computer system, and a Broadband Router is the same as a PC, the CPU of the central processing unit is used, while the CPU of different broadband routers is generally different. The CPU is also the processing center of the Broadband Router.

I have found that many articles on Broadband Router shopping guides emphasize that the CPU performance does not fully reflect the performance of the Broadband Router, but is reflected by indicators such as the throughput, latency, and route computing capability of the Broadband Router. Therefore, when choosing and purchasing a Broadband Router, many users intentionally or unintentionally ignore the CPU performance of the Broadband Router and pay attention to the features of the product. As a matter of fact, in a Broadband Router, especially a new generation of broadband multi-Wan broadband routers that are widely used, more advanced functions require more complex computing capabilities, the CPU performance directly determines the hardware performance of the product and cannot be ignored by prospective consumers. The throughput, latency, route computing capability, and other important indicators of the frequently-emphasized Broadband Router are all closely related to the CPU performance.

First, many buyers pay more attention to the Broadband Router throughput, Broadband Router throughput refers to the internal LAN and the external network between the data traffic, that is, the data traffic between the LAN-WAN. Instead of the traffic between LAN-LAN, it refers to the number of packets passed per unit time without packet loss. If the throughput is too small, it will cause the network bottleneck to manage the traffic as a data channel between the Intranet and the Internet, negatively affecting the transmission efficiency of the entire network. Throughput is the hardware performance indicator of the Broadband Router. The bandwidth router-CPU will affect the throughput value.

The other is latency, which is mainly caused by two factors: the link transmission latency caused by the transmission channel and the queue latency. The former mainly depends on the physical media used by the transmission channel (for example, optical fiber transmission or wireless transmission) and the delay is fixed. The latter largely depends on the processing speed of the gateway node's Broadband Router, that is, the computing capability of the bandwidth router CPU. Other important indicators, such as the route computing capability, are related to the CPU clock speed and bus width (16-bit or 32-bit) the Cache capacity and structure, internal bus structure, and computing mode are related to each other. In any case, the performance of the Broadband Router processor, especially the multi-Wan port Broadband Router, should not be ignored. So what kind of Broadband Router does the user need in the current network conditions? And what are the CPU requirements of the next generation of broadband routers?

The network application environment is relatively simple, and there are few applications and services in the network, which has low requirements on the service performance, reliability, security, and service quality of the Broadband Router. However, in recent years, the Network has developed faster and faster, and people have higher and higher requirements on people. We can see that the operating environment and business characteristics of the application environment are different, and the network construction methods are also different, the demand for Broadband Router services is also increasing and complicated. For example, Internet cafes are growing in size, requiring a wide range of network applications and a variety of application requirements from different users. Therefore, the functions of broadband routers for Internet cafes are complete and stable. For example. More and more enterprises have introduced a large number of businesses into the enterprise network, and also need to establish enterprise VPN networks and other businesses, which each need to obtain relatively independent resources, to meet the requirements of different aspects and applications.

The business types provided by the Broadband Router will become more and more diversified, and the pressure will also increase. The performance of the Broadband Router processor has been tested a lot. Performance has become a key factor in the development of broadband routers and their business capabilities. What a Broadband Router needs is not only a problem of "having" or "having" business functions, but how to provide high-quality service assurance for the entire network.

In the past, the processing speed of a Broadband Router was between-MHz. With such efficiency, it is sufficient to run a single WAN routing application. However, if the Internet cafe needs bandwidth management or Firewall actions, each packet needs to be filtered. At this time, CPU with insufficient performance may suffer from low response speed, insufficient corresponding data processing capabilities, and a large amount of CPU resources, reducing the process processing speed, not only can bandwidth management and other functions be used out, but also affects the original bandwidth and outweighs the loss. For example, when an enterprise wants to start QoS, security, and VPN services, the performance of the processor may drop sharply, which may lead to performance bottlenecks or even crashes, then, the entire network is paralyzed or crashed. Of course, the theory is to provide users with high-quality services.

When the CPU performance does not meet the business processing requirements, the system performance will be greatly reduced, usually more than half of the loss. Therefore, high-speed CPU and large-capacity storage devices must be used for multi-WAN port broadband routers. Otherwise, they cannot be competent for the traffic of multiple WAN ports, not to mention the various heavy tasks of parsing each IP packet. From the above analysis, we can see that to provide high-quality service assurance, we must first solve the performance bottleneck-the CPU performance problem. To determine whether the bandwidth router's CPU meets the requirements, the following indicators and parameters are generally used for analysis and determination.
