The test of defer can mirror this to nod as a result, more direct of course way is TRacert, nevertheless use Tracert also needs the program of pair of our country networks to understand a little, otherwise you also do not know to jump where.

The result that actually defer checks is very important also, with us Www is browsed for exemple, just do not lose a bag, and the IDC with very long delay, the user also won't be accepted, who is willing to wait on a few minutes to see your webpage again?

What should mention additionally is defer in besides the size that should see test defer, or outside the size that a few times defer checks, see numerical value whether compare stability even, if have very big wave motion, to application of TCP of a few long connective, the influence that waits for application to a few video, speech will be very tremendous.

HTTP downloads speed

HTTP download speed basically is to show the speed that visits a website has many fast, can deliver the webpage thoroughly inside how long come over. The direct sense that this one value can give authority will be a few more immediate, cost more length no longer here. .

Additionally we look to be measured in the method that variance also introduced in the test the stability of IDC. Because a lot of elements may affect the rate that the network downloads, the route that includes a course by implement jump several, the bandwidth of IDC, IDC receives the quality of the network, these metropolises affect final test result. The network wave motion in transmitting a process can affect final download rate. So we are in every IDC 6 48 hours bit in the result analysis of this second test nod with 3 (all telecommunication, entire network is connected) variance of computation of all available data, will see the difference of they and average, come whether can the test data that judges the IDC that be measured fluctuate very big, if wave motion is very big, bring an influence likely to the use of the user.

Additional, the quality that judges a network how, should combine download speed and defer to be judged together.
