【School】 choose weak commercial performance firewall need to reference.

<br> <BR> 1, the throughput test <BR> The test used to determine the firewall to receive and send data packets without loss in case of maximum data transfer rate, is to test the firewall in the normal operation of the data transmission capacity ., is the basis of other indicators. .It reflects the ability of the firewall packet forwarding. .Because the data stream will result in the loss of a high-level agreements as a significant delay in waiting for a timeout, so that the firewall actual maximum data transfer rate is very useful. .The indicators can also be used to determine firewall device over the stability of their own case load of questions. .<BR> Higher throughput makes firewall more suitable for the network core layer on the flow of demanding network environment, the firewall will not become a bottleneck in network performance will not affect the normal business communications. .<BR> 2, <BR> delay is the delay in testing the test data frame from the last bit into the DUT port until the first test data packet to another port bit away from the device under test interval. .<BR> Indicators for some of the real-time delay-sensitive use, such as Internet telephony, video conferencing, database replication such as the use of very large, so a good indicator for evaluating the delay performance of the firewall is key. .<BR> Delay tests for all frame sizes of 50% and 100% throughput under implementation, is the horizontal comparison of the results of store and forward delay. .Single forward delay (a rule, two GE ports, 2Gbps bi-directional flow, respectively, in 50% and 100% throughput under test). .<BR> 3, packet loss rate test <BR> test used to determine the loss rate at different transmission rates firewall packet loss percentage, the purpose is to test the firewall in the ultra-performance under load. .<BR> For the financial, securities, e-commerce and other industries involved in online transactions, the loss rate of data transmission requires very harsh, even if the system exists within the structure of error correction, proofing mechanism, but a lot of packet loss rate will cause frequent roll .-back action, delay the timely implementation of major transactions, affecting the confidence of traders on the system that led to the loss of customers. .Therefore, packet loss rate index for the banking system to shut the main network. .<BR> For 64 ~ 1518byte the frame size, respectively 40%, 70%, 100% wire-speed test execution. .Single packet loss rate (a rule, two GE ports, 2Gbps bi-directional flow at 40%, 70% and 100% wire-speed packet loss rate under). .<BR> 4, concurrent connections test <BR> the tests used to test the firewall's TCP can establish the maximum number of concurrent connections. .<BR>.
