Gordan: On Thursday 12/28 you enclosed with the text below: >May I ask: Is AS690 the Autonomus System number for ANS?

If it was a better format, it couldn't be >used because the PRDB had components that were not transferrable to >RIPE? Are you saying that to transfer the ANS database into RIPE format >would have taken a very sizable number of person months? To help you understand the PRDB, I offer some historical information from an engineer's perspective: The concepts and the some of the code for the PRDB database system predate even ANS's creation. The PRDB concepts come from the early days of the NSFNET and trying to run that specific network. The multiple ISP/NSP world has come upon the Internet to replace the NSFNET. This change was requested by some people to provide a fair marketplace in the Internet. The routing registration shift from PRDB to RIPE/IRR format reflects a shift in the Internet reality, not an ANS database specific project. The effort to keep the NSFNET service current was an engineering effort over years. We moved from 1/3 T1 to T1 to T3. Our databases also migrated implementations and service capabilities. The PRDB was the third in a series of the databases. RIPE could be considered the fourth. I hope this has helped fill in some history around Curtis's comments. Sue Hares Merit
