Tracert To Los Angeles

[pedro01]

Hi All

Our company has an office in Bangkok & Manila, we have a 1024kb Loxinfo line & somehow the speed from Manila to our HQ in LA is faster than from Bangkok.

Doing a tracert - I can see that from Bangkok - it's hopping all over the place. From Manila, it's much more sane.

Doesn't Thailand have any direct connections to USA ? We seem to get routed via Tokyo...

Funny you should ask... I've usually noticed the same path via verio.net from thailand->japan->US but today I see one hop from a CAT router to a teleglobe.net router called if-1-0.bb3.LAA-LosAngeles.Teleglobe.net but the big jump in latency happens a few hops earlier as if CAT's IP numbers are being applied to equipment on the US side of the ocean... Then it hands off to verio.net which must all be in Los Angeles because of the short latencies:

Note that through True high speed (consumer) ADSL it takes the first dozen hops just to get to the point where routers stop being called asianet.co.th and start looking more like CAT addresses! I am sure someone better at googling than I should be able to find an overview of Thailand's Internet links. The routes you get will be largely due to ISP peering relationships and less due to actual best path for you.

Thailand's internet linkage map is at nectec (www.nectec.or.th). 200+ ms is about typical for a leased line, which has the least hops and the highest priority. For consumer lines, it's more in the 300+ms range (if you've got a decent line).

I got there in 16 hops, but it still went through Japan:
