  3. ™ H.323 Forum – November 2002 – New York, NY, USA

  4. ETSI Project TIPHON • ETSI - European Telecommunication Standards Institute • TIPHON - Telecommunications and Internet Protocol Harmonization over Networks • Started 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) H.323 Forum – November 2002 – New York, NY, USA

  5. PSTN 4 5 2 1 3 NGN Interwork NGN with TDM Applications Customer Cut-over TDM network Create NGN network Softswitch • IP-enabled access • Dial-in • xDSL • Fiber-to-the-X Support Voice over Packet Access Build-out Packet Access Migration to NGN H.323 Forum – November 2002 – New York, NY, USA

  6. Design principles (1) • A usable NGN architecture supportsMultiple Domains H.323 Forum – November 2002 – New York, NY, USA

  7. Domain 3 Domain 1 Service Domain Service network Client Domain 2 Client Transport Network Transport Network Multiple Domains • each Domain may have its own policies • each Domain may have its own commercial goals • and possibly its ownprotocols & transport. H.323 Forum – November 2002 – New York, NY, USA

  8. 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 H.323 Forum – November 2002 – New York, NY, USA

  9. 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 H.323 Forum – November 2002 – New York, NY, USA

  10. 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) H.323 Forum – November 2002 – New York, NY, USA
