Select vro from CPU (1)

The CPU of the router is very important.

CNET China. ZOL reported on September June 2: in the online world, each router is like a post office, which classifies and integrates the information on the network and transmits them to the destination according to the address. 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 router? This article will focus on the performance of the vrocpu CPU to provide you with a practical procurement advice.

Broadband routers and CPU performance cannot be ignored

As an interface device for Internet cafes, a router plays a vital role in the entire architecture. In terms of structure, a router is a dedicated computer system, and a router is the same as a PC, the CPU of a central processing unit is used, and the CPU of different routers is generally different. The CPU is also the processing center of the router.

Vro processor performance should not be ignored

I found that in many previous articles about vro shopping guides, many places emphasize that CPU performance does not fully reflect vro performance, but is reflected by indicators such as vro throughput, latency, and route computing capability. Therefore, many users intentionally or unintentionally ignore the CPU performance of routers when selecting and purchasing vrouters, and pay attention to product functions and other factors.

As a matter of fact, in routers, especially the next-generation Broadband Multi-WAN routers with common applications, 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.

These important indicators, such as the throughput, latency, and route computing capability, are all closely related to CPU performance.

First, many buyers pay more attention to the router throughput, the throughput of the Broadband Router 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 router, that is, the computing and processing capabilities of the router CPU.

Other important indicators, such as the route computing capability, are related to the CPU clock speed, 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 router, especially the multi-Wan port Broadband Router processor, should not be ignored.

So what kind of Router does the user need for the current network conditions? And what are the CPU requirements of the next generation of routers?

Next-generation Router
New-generation routers provide high-quality services and performance

The network application environment is relatively simple, and there are few applications and services in the network. Therefore, it has low requirements on the service performance, reliability, security, and service quality of routers. 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, more and more demands for router services are becoming increasingly complex. 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.

Vro provides more and more business types, and the pressure increases accordingly. The performance of the vro processor has been tested a lot. Performance has become a key factor in the development of routers and their business capabilities. What a 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 router was between-MHz. With such efficiency, it was sufficient to run a single WAN routing application. However, if Internet cafes need 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, multi-WAN Port Routers must use high-speed CPUs and large-capacity storage devices. Otherwise, they cannot handle the traffic of multiple WAN ports, not to mention the various heavy tasks of parsing and processing each IP packet.
