Broadband Router. Some product firewall rules are complex and can filter many items, and some product rules are less and simpler. There are many and complex rules. The time that the CPU uses to filter data is long, the rules are few and simple, and the time that the data is filtered is short. This has a huge impact on the Throughput test data. To be fair, it is reasonable to disable the firewall when testing the router Throughput, especially when comparing the performance of different products.
The test instrument we use is smartbits 6000B, a Bollen communications company. The console uses an HP desktop that is configured as a PIII 1ghz/128m memory/20g hard drive.
When testing the performance of the hundred Gigabit Firewall, use the two 10/100BASE-TX ports of the smartbits 6000B 10/100m Ethernet smartmetrics module, which is directly connected to the internal and external network of the firewall,
-to-wan, which should be measured in the case of NAT opening and firewall shutdown, respectively, with two different test methods, smartbits and chariot. When using the Smartbits method, compare the 64Byte packet test data, and stand the contract; Chariot testing is best done under multiple connections, you can generally choose 100 pairs of connections can basically see the difference between the product DN

However, if it is a corporate network, most people are busy designing, writing reports, and making plans, at the same time, only a small number of people are using the network, and most of the data is flowing inside the enterprise network, so the router has a very low load, so you can load more clients at the same time.

When using the Smartbits method, compare the 64-byte packet test data and determine whether to compete. The Chariot test is best performed under multiple connections. Generally, you can select 100 pairs for the connection to see the differences between products.

of the data is flowing inside the enterprise network, so the router load is very light, then you can load more clients at the same time. If the maximum load is 253, it makes no sense, because the maximum number of IP addresses that DHCP can allocate is 254, and the number of IP addresses that DHCP can use is 253, this kind of metric cannot be called. It is basically a hit person. Therefore, we need to look at the actual load capacity of a router, rather than the theoretical load capacity.

believes that this data packet filtering function is very important for vro settings. Therefore, the test focuses on the impact of the data packet filtering function on the Performance of vro settings. In this test, each manufacturer uses a pair of router settings of the same model which are connected by two T-1 interfaces using the adapter cable. Product Configuration (with two T-1 lines and two Ethernet interfaces of the router) can be considered as the most common situation of enterprise rou

The Chariot test is best performed under multiple connections. Generally, you can select 100 pairs for the connection to see the differences between the products.
Causes of router price impact
After the above discussion, we can finally return to th
uncertainties and spoofing nature of the load capacity, another indicator is also quite concerned, that is, throughput. Throughput refers to the amount of data that the router can process per second. This parameter refers to the throughput of the LAN-to-WAN. The measurement result is that when NAT is enabled and the firewall is disabled, use the Smartbits and Chariot test methods respectively. When using the Smar

the grade price will certainly not fall, the basic decision of the router grade is the load capacity is also called the number of machines and throughput two aspects.
With the number of machines is very good understanding, for example, the maximum load of 235 units, but this index is basically deceptive people, there are too many uncertainties and cheating nature, mainly depends on the actual load capacity ah; What is the throughput? The so-called throughput is the amount of data that the valu

Package receiving is the opposite process. The vro is basically the same, but what you send and receive is data. Throughput is equivalent to the package processing capability in the post office unit time, which is an intuitive reflection of the router performance. Generally, the throughput is the test data obtained when NAT is enabl
forwarding performance test. The 24 ports use a full mesh test. The topology is shown in Figure 1. A packet of 64, 512, and 1518 bytes is used, and each port has two MAC addresses, the packet loss rate, throughput, and latency of a 24-port full-Gigabit Switch with 120 seconds and 100% seconds under 90% loads were tested.
According to the test results, most manufacturers have delivered satisfactory answers, and the 24-port full Gigabit Switch has achieved zero packet loss and a throughput of 100
with insufficient bandwidth to improve utilization. We tested layer-3 QoS by using the SmartBits 6000C tester to connect ports 1, 2, 3, and 4 of a 24-port full Gigabit Switch, ports 1, 2, and 3 send SNMP, POP3, and HTTP data streams that simulate UDP ports 161,110 and 80 to ports 4 at the same time.
The priority of the three data packets is the highest in the 24-port full Gigabit Switch, the highest in SNMP, the lowest in POP3, and the lowest in HTTP
, the user does not apply a router to replace the firewall. However, the tester believes that this data packet filtering function is very important for the router. Therefore, the test focuses on the impact of the data packet filtering function on the performance of the router.

. Generally, the throughput is the test data obtained when NAT is enabled and the firewall is disabled. There are two ways to test the throughput: Smartbits test and Chariot test. The results can be different.
