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: beehive:~$ ping www.tokyonet.ad.jp PING www.tokyonet.ad.jp: 64 byte packets 64 bytes from 202.239.61.53: icmp_seq=0. time=52. ms 64 bytes from 202.239.61.53: icmp_seq=1. time=40. ms 64 bytes from 202.239.61.53: icmp_seq=2. time=78. ms 64 bytes from 202.239.61.53: icmp_seq=3. time=37. ms beehive:~$ ping home.netscape.com PING www30.netscape.com: 64 byte packets 64 bytes from 207.12.240.31: icmp_seq=0. time=222. ms 64 bytes from 207.12.240.31: icmp_seq=1. time=271. ms 64 bytes from 207.12.240.31: icmp_seq=2. time=220. ms beehive:~$ ping gol.com PING gol.com: 64 byte packets 64 bytes from 202.243.48.4: icmp_seq=0. time=679. ms 64 bytes from 202.243.48.4: icmp_seq=1. time=386. ms 64 bytes from 202.243.48.4: icmp_seq=2. time=437. ms 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.

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. ------------- Craig Oda craig@example.com TWICS - Japan's First Public-Access Internet System, TWICS - IEC Building, 1-21 Yotsuya, Shinjuku-ku, Tokyo 160 JAPAN Main Reception: 03-3351-5977 Fax: +81-3-3353-6096 Customer Service: 3351-5481 Corporate Sales/Support: 3351-8452 ----------------------------------------------------------------- a word from the sponsor will appear below ----------------------------------------------------------------- The TLUG mailing list is proudly sponsored by TWICS - Japan's First Public-Access Internet System.
