2 Technical Aspects of the Transitional Process Mexico City, 11/12 Nov 2002 Data Input Flat file in RPSL format 3 object types (ARIN old DB) –Aut-num –Inetnum –Person Entity is an attribute of the 2 services objects No strong ownership relation between service objects

3 Technical Aspects of the Transitional Process Mexico City, 11/12 Nov 2002 LacNIC Objects Entity Block (inetnum) ASN (aut-num) Person

4 Technical Aspects of the Transitional Process Mexico City, 11/12 Nov 2002 Objects relation Entity ASNBlock Person 1 N N

5 Technical Aspects of the Transitional Process Mexico City, 11/12 Nov 2002 Data Manipulation Two temporary object (OldEnt and OldId) were created to import the data During the import an algorithm cleaned up the owner name and compared them between the 2 services objects. The cross relation was got from these information. Name clashes were treated by manual processing. The adopted transition schema provides only full whois and reverse publication services until the update of the information is made. Block boundaries were adjusted to prefixes. Represented reverse delegation on the Whois were adjusted to prefixes and represent exactly the requested reverse delegation.

6 Technical Aspects of the Transitional Process Mexico City, 11/12 Nov 2002 Migration / Verification The process took 2 weeks between the arrival of the first dump and the take over of the reverse zone file generation and publication After the final import the data was verified by independent reverse publication(ARIN and LacNIC) and objects count.

7 Technical Aspects of the Transitional Process Mexico City, 11/12 Nov 2002 Transition Schema To update the data the customer need to contact RSG. The customer receives a password and could update the information directly on the system. During the update the owner data is imported in a final object and the customer receives full services directly on the system interface. The adopted policy to provide smooth transition is: – Customer is allowed to update the data on request – Customer is obligated to update the information during new allocation. So far we have 10% of the database updated.

8 Technical Aspects of the Transitional Process Mexico City, 11/12 Nov 2002 Data Protection Database replicated online. Read load separated from master database Two full flat file backups during the day One daily copy on tape to a safe External online replication
