As it is shown in figure 5, be the test result analysis figure of distributed network measurement system of the present invention, from throughput test results it can be seen that handling capacity along with data packet length increase and in the trend being incremented by.This is because network interconnection device is under agreeing to bandwidth, the more little quantity causing test packet of length becomes big, and equipment under test processes the time of these data costs also can be elongated；On the contrary, length is more big, and the impact of handling capacity is more little.This is because test rate is all in units of bps, when data packet length increases, in the unit interval, the data packet number of process reduces, and the time that router processes individual data bag does not increase, and therefore forwarding rate is accelerated, and then increases handling capacity.From delay testing result it can be seen that time delay presents increasing trend along with the growth of length.This is because individual data packet length is more big, it is more long that network interconnection device processes the time, and corresponding time delay also can increase.The result of packet loss test is similar with throughput test results, and along with being incremented by of length, packet loss presents the trend successively decreased.
Embodiment two
Referring to Fig. 6, for the flow chart of distributed network measurement system 10 network performance measurement of the present invention, in conjunction with flow chart, it is explained in detail.
1) start application to measure；
2) pattern according to the measurement demand configuration testing terminal 20 of user, is select active method of testing or select Passive Test method to carry out applied in network performance test, and what native system adopted is active metering system；
3) application measurement and control center 30 is relevant thread and memory space complete test, and this system supports that multi-user carries out applied in network performance test, so have employed the technology of multithreading, it is possible to extend multiple function；
4) start test terminal to complete to send or receive packet；Start test terminal 20 to test, each test terminal is configured with agent service, agent service receives user by the test instruction sent of server in measurement and control center 30, then passing through testing tool Iperf adopts passive measurement mode to obtain initial data, initial data is passed to measurement and control center 30 and carries out pretreatment, judge that whether packet is legal, be namely completely unsatisfactory for the requirement of test packet size required for RFC2544 agreement.It is unsatisfactory for giving measurement and control center 30 and re-starts pretreatment；
5) measurement and control center 30 above-mentioned packet is analyzed, abstract, calculate formed visual test result, show in web interface.
By the measurement to network performance of the above-mentioned distributed network performance measurement system, contrast with U2000 network management system in prior art, following conclusion can be obtained:
