Read ping and tracert result.

At the very early time, i had learned all the ping and tracert command, but when i see the records that prompt out from the screen, i can't comment any for it.

But now, i able to read/study a bit the ping and tracert result. Share with you guys.

for example : i trace from my site to the route-views.oregon-ix.net

C:\Documents and Settings\Fein>tracert route-views.oregon-ix.net

Initially from my site trace to the oregon router. So it starting from my site to the oregon site, so it starting from my gateway to my router and go through the asianetcom, LosAngeles, some US there router, and finally go to the end point. We can see that the time is around 200ms, it is consider faster. Let say is beyond than 500ms (experience!?!?), it is consider high latency(means slow). From malaysia to US just 200ms!??! not faster ???!??!

From the reverse router provided, it is the same thing, it starting from the oregon router and it's router, then asianetcom then our router. It also around 400msec, it is acceptable.

Now, Why the traffic we go and the traffic we back is going through different path??!?!? It is because every ISPs is link with different upstream and their borders gateway will decide to go through the "shortest" pathes they choice.

Then why the traffic will go more hops(router) and back less hops(router)?!?!?!? As i know, it was because every having their own upstream, if the provider don't have the direct peering with the specific provider, then it will go through an alternative ways. For example,it TM not peering with maxis directly, we might need to go throught TM-Digi-maxis, Will increase one hop between it.

Then why they don't want direct peering, is more faster what?!?!? ya.. is more faster, but the things is -- the two ISP provider don like each others(kidding), it was because money lo, let say TM buy bandwidth from Maxis is more expensive then buying traffic with Digi, then why TM buy it?!??! all is because money ma... haha

Now malaysia got MyIX liao, don worry.. if wanna to launching the local website is more faster, they stick together liao ma.. ahha

What is MyIX?!?!? go check google la.... google can shows to you de...

by the end... now very morning lei.. sleepy la... If i am wrong.. don shoot me... if i am right.. please comment me.... say that : leng zai fei... Hot
