1) CPU
The CPU is the core component of the router. Different series and models of routers have different CPUs. The quality of the processor directly affects the router's throughput (routing table lookup time) and routing computing capability (affects network routing convergence time).
Generally speaking, processors with a main frequency of 100M or below belong to a lower main frequency. Such low-end routers are suitable for ordinary households and SOHO users. 100M to 200M is a medium frequency, and above 200M is a higher frequency, which is suitable for Internet cafes, small and medium-sized enterprises and branches of large enterprises.
2) Memory
The unit of memory can be Byte (byte) or Bit (bit). The difference between the two is 8 times the capacity (1Byte = 8 Bit). In the current router memory, 1M to 4M Bytes is low, 8M Bytes is medium, and 16M Bytes or more is large memory.
3) Throughput
The data in the network is composed of data packets, and the processing of each data packet consumes resources. Throughput refers to the number of data packets passed per unit of time without packet loss, that is, the ability of the device to forward data packets, and is an important indicator of device performance. The router throughput represents the amount of data that the router can process per second, and is an intuitive reflection of the router's performance.
4) Support network protocol
Just like people speak a certain language, there is also a language between computers on the network, which is the network protocol. Different computers must abide by the same network protocol to communicate. Common protocols are: TCP/IP protocol, IPX/SPX protocol, NetBEUI protocol, etc. IPX/SPX is used more in LAN. If users access the Internet, they must add the TCP/IP protocol to the network protocol.
5) Wire-speed forwarding capability
The so-called wire-speed forwarding capability means that when the maximum rate of the port is reached, the data transmitted by the router is not lost. The most basic and important function of a router is data packet forwarding. Forwarding small packets at the same port rate is the biggest test of the router's packet forwarding capability. The full-duplex wire-speed forwarding capability refers to the minimum packet length (Ethernet 64 bytes, POS port 40 bytes) and the minimum packet interval (in compliance with the protocol) are bidirectionally transmitted on the router port without causing packet loss.
Wire-speed forwarding is an important indicator of router performance. Simply put, as much traffic comes in, as much traffic goes out, the throughput will not drop due to the problem of device processing capability.
6) Number of belt machines
The number of machines is easy to understand, that is, the number of computers that the router can load. In the performance parameter table introduced by the manufacturer, you can often see that the router can carry 200 PCs and 300 PCs. However, in many cases, the performance of the router is very different from the nominal value. This is because the number of routers with a router is directly affected by the network busyness of the actual use environment, and the number of routers in different network environments varies greatly.
