Network test of integrated wiring system

At present, users and contractors have attached great importance to the certification test and acceptance of the integrated wiring system.

Not only will the user be required to have complete test reports and documents, but also the contractor will provide them on their own initiative. In the testing field, the United States Fluke Network Company (Fluke) DSP series Digital cable certification instrument has become a user, engineering, Third-party testing of choice for testing equipment. Integrated wiring engineering Design, construction, acceptance and use of fully standardized.

However, we can not but note that the network system in the use of very few users before rigorous testing, in the network system did not clearly understand before, the risk of putting into use, once the hidden trouble, will make network management personnel unprepared.

Therefore, there are some basic tests to be done before your network is officially put into use. We recommend that users perform the following tests.

First, physical fitness test

Physical fitness test, also known as the impact test, refers to the network in the high flow state of the network to the ability to fight paralysis, requiring more than 92% of the flow of the network will not be paralyzed, more than 97% for the outstanding. The flow type is determined according to the different network equipment, to the Exchange network, the impact flow is aimed at the primary server, the switch ports, the router's normal IP packet and the 3,000-byte long frame (traffic 80%), 40-byte short frame (traffic 25%). We can use the Fluke network a little pass throughput test function, enterprise Network Tester 68 series of traffic send function, Network Synthesis Analyzer 2.0 edition of traffic send function. ---http://bianceng.cn (computer science)

Second, the channel test

The channel test primarily verifies that the designed or leased channel is capable of loading predetermined targets. The routing channel test verifies that the channel passes the capacity of the established traffic, completes more than 80% traffic for qualified, and completes over 90% traffic for excellent. Bridge channel test requirements to achieve 90% qualified. This test can be done using the Fluke Network, 683 or network analyzer.

Third, the important network equipment load capacity test

After the switch, server and router load 40% traffic to verify the liquidity and speed, subjective evaluation should basically not feel the network slows down, the ICMP ping test in the LAN less than 2ms qualified, 50% load, ICMP ping test is less than 4ms,60% load, The ICMP ping test is less than 6ms. This test can be accomplished using the ICMP test capabilities of a network-bit, 683-or network-integrated tester.

Iv. Network protocol statistics and user statistics

When busy, the application protocols of the network are counted, the unqualified protocols are cleared, the users who send and receive the most packets are labeled, and the bandwidth is counted. This test can be carried out with the functions of protocol MATRIX, top SENDER, top conversation and so on, which is a little pass of the Fluke Network, 683 or network synthesis tester.

V. Benchmark TEST

Record the network traffic, collision, broadcast, error and other long-term data, analysis of network traffic change law. Helps optimize network performance and troubleshooting. The test can be done using a little pass, 683, or network analyzer, which can monitor the network for a long time, and use the reporting software to draw a cycle chart of network traffic.

Vi. single-Machine connectivity test

Test the network adapter's working protocol and physical parameters. Test single network speed under 40% loading conditions, subjective evaluation, if the link flow from 30% to 40% when the speed is basically unchanged, then the link acceptance pass. This test can be used in the Fluke Network, 683 or network analyzer to send traffic, using the network multimeter in line test network card and observe the link traffic reflected.

Seven, network card, hub, switch port test

Test the signal waveform and jitter, test work agreement, judge the Protocol matching status, require 100% match for qualified. This test can be used as a network multimeter in line style on both sides of the protocol matching, set the matching of comparison, can be 683 of the EXPERT-T function to test and hint of failure.

Viii. Network record-keeping test

Documentation of network devices, including name, IP, Mac, and topology map. Fluke Network, 683, Network synthesis Analyzer, network stethoscope can be used for document filing, and lan-mapshot coordination can draw a network topology map, for the network system to provide complete documentation.

Monitoring the performance parameters of network equipment

For the time being, we only recommend the link connectivity test under 80% loading conditions to observe the error and collision index. This test uses the flow-sending function of the Fluke Network tester and the network monitoring function to simulate the load flow of the network and test its response.

10 or seven-layer flow statistic analysis

For statistical analysis of the flow rate of each layer, the application of seven layers can be statistically and analyzed by using the analysis instrument of Fokker Network or protocol analyzer and Flow Analyzer.

When your network has passed these tests, you will not only be assured of running now, but you will also be able to quickly detect, diagnose, and isolate failures in the future as a result of updates, expansions, and changes, until troubleshooting occurs.
