4. Sponsored in part by: H.323 Forum – November 2002 – New York, NY, USA ETSI Project TIPHON ETSI - European Telecommunication Standards Institute TIPHON - Telecommunications and Internet Protocol Harmonization over Networks S tarted in May 1997 with short term goals to standardize the H.323 gateway In 2000, refocused to develop the specifications (protocol profiles and test suites) to enable end-to-end telephony and multimedia communications services over Next Generation Networks (NGN)

Multiple Domains Multiple Domains

8. Sponsored in part by: H.323 Forum – November 2002 – New York, NY, USA Design principles (2) A service is rendered in exchange for money. –Services are explicitly requested and explicitly stopped, this provides basis for charging –Services are only delivered to authorized users –Services are only sellable if QoS and security can be guarantee  Dedicated VoIP infrastructure is expensive to maintain –Only a converged (packet) network that supports multiple services over one infrastructure can be commercially viable  NGN will be deployed in an unbundled, open telecom world –Allow competition among SPs on something other than price –Support hooks for value add

9. Sponsored in part by: H.323 Forum – November 2002 – New York, NY, USA Design principles (3)  Affordable multi-service architecture; Do not mix application and transport!  Support services for roaming users  Support unique services –Service provided from HOME service provider  Service provider determines media route –Service may include in-band media events –Support for Lawful Intercept –Call Routing follows the money –QoS flows cost money so service providers will do least cost routing on it (providing QoS can be met)  Technologies come and go: Be technology independent

10. Sponsored in part by: H.323 Forum – November 2002 – New York, NY, USA Development Process TIPHON Release Scheduling –Identification of clearly understood and scoped set of requirements per release Step A = Release definition –Declaration of plan with the identification of the associated work items Step B = Capabilities & Requirements –Specification of Service Capabilities and Service Independent Requirements Step C = Reference Architecture –Definition of functional entities and related information flows, developed independently of underlying technology issues Step D = Implementation framework –Definition of protocol-neutral framework together with identification of key interfaces and definition of related “TIPHON Meta-protocol” Step E = Technology mapping & Verification –Mapping of TIPHON meta-protocols into supported technologies (e.g. H.323) –Creation of PICS and related test suites for resulting protocol profiles –Creation of interoperability test scenarios (e.g. H.323 - SIP)
