Database Software v3
• Functionality
• Architecture
• Performance
9Andrei Robachevsky . 12th APNIC Open Plicy Meeting, August 2001, Taipei, Taiwan . http://www.ripe.net
New version of the RIPE Database
• Supports RPSL (RFC2622)• Extended syntax• New objects and attributes
• Supports RPSS (RFC2725)• New authorization rules
• Supports RAToolset• RtConfig -protocol ripe
• Code is completely rewritten
10Andrei Robachevsky . 12th APNIC Open Plicy Meeting, August 2001, Taipei, Taiwan . http://www.ripe.net
RPSL features
• Provides rich syntax for expressing routing policies• router configuration ready
• RPSL syntax extensions apply to all object types• end of line comments• line continuation• order of attributes
• New objects• as-block, as-set (as-macro), route-set (community)• peering-set, filter-set, rtr-set
• New attributes• member-of, mbrs-by-ref• mnt-routes: <mnt_name> [ rpsl list of prefixes | ANY]• referral-by: <mnt_name>
11Andrei Robachevsky . 12th APNIC Open Plicy Meeting, August 2001, Taipei, Taiwan . http://www.ripe.net
Security features
• Provides strong security mechanisms• Protection of individual objects• Protection of IP address space• Protection of ASN space• Protection of route space• Protection of set membership• Protection of hierarchical set names• Protection of domain object space
• 4 supported auth schemes• GPG public keys are supported
12Andrei Robachevsky . 12th APNIC Open Plicy Meeting, August 2001, Taipei, Taiwan . http://www.ripe.net
New software• Mainly in C, multithreaded
• CPU: 70% idle
• RDBMS as a back-end• MySQL, customized transaction support
• In-memory radix tree for IP lookups• also more and less specific lookups for reverse delegation
domains
• MIME and GPG support • correct PGP keys are also accepted
• Automatic access control• separate accounting for public and contact data

Transition phases
• Pre-migration period• Conversion to RPSL• Prototype servers
• Transition period• 23 April: Migration Night• RIPE-181 compatibility mode
• Finalizing the migration• ftp site structure• deprecating legacy stuff
17Andrei Robachevsky . 12th APNIC Open Plicy Meeting, August 2001, Taipei, Taiwan . http://www.ripe.net
Pre-migration: RIPE181 -> RPSL• Sets
• as-macro: <macro_name> => as-set: <macro_name>• community: <comm_name> => route-set: RS-<comm_name>
• Reserved prefixes (RP)• AS-, RS-, RTRS-, FLTR-, PRNG-• mntner: <RP><mt_name> - 9 cases, all resolved by the owners• as-name: <RP><name> => ASN-<name>
• Mandatory attribute: mnt-by (except dn, pn, ro)• no mnt-by => mnt-by: RIPE-NCC-NONE-MNT• no mnt-by (aut-num’s) => mnt-by: RIPE-NCC-AN-MNT
• New attribute: referral-by• => referral-by: RIPE-DBM-MNT
18Andrei Robachevsky . 12th APNIC Open Plicy Meeting, August 2001, Taipei, Taiwan . http://www.ripe.net
Pre-migration: prototype servers
• Near real-time mirror of the RIPE Database• whois -h rpsl.ripe.net• contains live RIPE Database in RPSL format
• Test server for submissions• mail <auto-rip@ripe.net>• whois -h rpsl.ripe.net -p 4343
• NRTM• rpsl.ripe.net, port 4444• please contact <ripe-dbm@ripe.net>
19Andrei Robachevsky . 12th APNIC Open Plicy Meeting, August 2001, Taipei, Taiwan . http://www.ripe.net
Pre-migration: milestones
• April 5 ripe-dbase-3.0 release
• April 12 Advised mirrors’ switchover
• 4 servers switched to the RPSL mirror
• April 19 Migration if the TESTDatabase
• dress rehearsal of the migration
20Andrei Robachevsky . 12th APNIC Open Plicy Meeting, August 2001, Taipei, Taiwan . http://www.ripe.net
Transition: Compatibility mode
• RIPE-181 updates• can be sent to a separate mail robot• automatically converted to RPSL
• PGP authentication• cannot be used
• RPSL syntax rules• empty attributes are not allowed• optional -> mandatory• no aliases• no prefix notation
21Andrei Robachevsky . 12th APNIC Open Plicy Meeting, August 2001, Taipei, Taiwan . http://www.ripe.net
Transition: issues
Routing Policy System Security (RFC2725)• new authorisation rules for route creation • need to duplicate objects in the RIPE DB
• encompassing inetnum with NONE auth for mnt-routes• as-blocks for non RIPE space with NONE auth for mnt-lower
• low level of security in non RIPE space• still apply in RIPE-181 compatibility mode
• V2 undocumented features• leading white space stripping• correcting misspelled attributes• filtering out empty attributes
