It’s not so easy• Provisioning

• Data Publishing (AXFR, EPP, SOAP & Security)• Data Poisoning, Mis-Routings & Policies

• Address Resolution• TN URI, URI SRV or• Originating Based, Split View – SPID, or ANI ?

• Multiple Resolutions / Queries• LNP, Infrastructure, Federation(s!)

• Privacy / Security / Identity• Identity of Server – DNS-SEC• Identity of Client – ACL, VPN or New Standard

• Data Propagation & Replication• Remote Query or Local Copy• Zone Transfers / Security Implications• Synchronization (1-many, Realtime) Challenge

Federation Interconnection

…and that is where Federation comes in

• Neutral party• Negotiates bi-lateral agreement with each participant,

including all the parts: directory, signalling, security, commercials and transport

• Absorbs the differences between VSPs

• XConnect Global Federation is an example of a successful federation. 400 VSPs around the world sharing traffic without transiting the old network—not paying their arch-enemy to carry their traffic

What does the Federation do?

• Provide secure route discovery (e.g. Federation ENUM)

• Absorb technical differences• Facilitate settlement (if any)• Eliminate the N2 problem• Implement and enforce policies

10

Why is it different?

• VoIP standards are not SO standard• VoIP industry has many more

participants• VoIP has low barriers to entry• VoIP is characteristic of dynamic and

innovative technology• VoIP has more security concerns
