Interim Report on Y2K Compliance in WIDE
WIDE Project, JAPAN
? M Root DNS Server
M Root DNS Server has been operational since late August, 1997 and is located one hop away from NSPIXP-2. Its environmental condition is the same as NSPIXP-2 described below.
The server system consists of two servers; one is used for primary and the other is for backup. When the primary server or the dns server process on the primary server crashes, the backup server should take over within a half minute using a routing protocol.
The hardware vendor of the system claims its Y2K compliance.NSTLalso lists its Y2K compliance.
As the system is equipped with two servers, we performed Y2K test on the backup system by setting its clock just before the midnight of December 31, 1999. We observed that the server continues its operation at least a few hours past the year 2000. Reboot operation on the system cause no problem at all. We also confirms that the hardware monitor program performs correct leap year calculation.
The servers run a variant of BSD UNIX operating system. So the system has serious Y2.038K issue, however, its operating system kernel and some application programs are Y2K compliant. Especially, the DNS server program is bind 8.2.1, whichInternet Software Consortiumclaims Y2K compliant.
The server system is connected to NSPIXP-2 through a router manufactured byCisco Systems. The vendor claims Y2K compliance on the hardware and a version of the software running on the router.
The transit service to and from the server is offered by many ISPs
There is an on-going project in which the server will also connect toJPIX, another major exchange point in Tokyo. This project will eliminate a single point of failure and extra robustness is expected.
NSPIXP-2 is one of the major internet exchange points located in Tokyo. It is equipped with fourCompaq(formarDigital Equipment) Gigaswitch/FDDI boxes, two of them are used for primary and the others are used for backup in FDDI dual home environment. It connects 42 commercial ISPs, 3 academic ISPs, and 5 other ASes as of July 1st, 1999.
The firmware in the FDDI switches has been upgraded in May 1999 to a version with Y2K compliance according to the vendor. There are a couple of FDDI concentrators by Compaq as well as a SX-6601 ethernet switch byNBase-Xyplex(formar Xyplex Corp). The vendors claim that those boxes are Y2K compliant.
? Environment of NSPIXP-2 and M Root DNS server
The primary electric power is supplied byTokyo Electric Power Companywith a battery and generator backup system maintained byKDD. The battery life lasts about 15minutes while the gas turbine generator should boot to feed the power in a few minutes. The cooling system is not backed up by the battery while it should restart automatically when the generator start to feed the power. The backup power supply system is already Y2K compliant.
NSPIXP-3 is one of the major internet exchange points located in Osaka. It is based on a couple of fastethernet switch manufactured byCisco Systems. The current version of the software running on the switches is not Y2K compliant and we are planning to upgrade the version of the software as well as its memory by the end of August, 1999.
? WIDE Backbone
The operation of NSPIXP-1 has been discontinued in March 1999.
