Re: Overseas connections a waste of time???



The connection speeds inside of Japan are much higher than
the connection speeds to places outside of Japan for 
must ISPs in Japan.  The instrastructure among Japanese
providers has improved recently.  Just as examples:
IIJ has a 45Mps feed to NSPIXP and redundant 1.5Mpbs
feeds to WIDE.  They are also connected to Tokyo Internet
with 100Mbps ethernet at their Network Operations Center.

I am connected to SprintLink, but my speed to someplace
like Tokyo Internet is quite fast:

Traceroutes often identify bottlenecks to a Japanese
site at places not related to NSPIXP or WIDE.

For some reason, traffic from Japanese sites to gol is being
routed through California in the U.S.  Route 5 is the Sprint
switching point in stockton California.  The return times
jumpt from about 50 to 220ms when the signal leaves 
Tokyo.

However, Tokyo Internet is using a Japanese switching point:

         ------

Leased line prices to NTT just dropped if you live
in Tokyo.  Within 15 km the leased line price for 64Kbps is
28,000 yen per month.  Internet port charges from ISPs vary from
50,000 to 600,000 yen per month.    NTT's proposed OCN network
will probably be the cheapest in Japan at around 25,000 yen/month.
However, Tokyo Internet and IIJ are probably going to try
and keep their port charges at around 90,000 yen/month.

How does all this relate to Linux in Japan?  Well, I'm very
satisfied with the connection of my Linux box to the Internet.
I home box has 128Kbps ISDN with STAC compression.  However, I almost
always only use one B channel at 64Kbps.  For me, it is
fast enough.  I get good performance with X-Windows or whatever
else I want to do.  I doubt that many home users will get
a leased line in 1997.  The prices are just too high and I
really don't see a need for it unless, the home user wants
to set up a BBS.  One issue I do see is with the planned
TLUG demonstration machine.  If we ever get a manufacturer
to donate a machine to us, we may want to get a permanent
Internet connection to the machine so genki TLUGers can
plan on it from the comfort of their home.
