  2. What is ETSI Project TIPHON? • TIPHON - Telecommunication and Internet Protocol Harmonization over Networks • Started in May 1997 with short term goals to standardize the gateway • H.323 focussed • De-composition of gateway: H.248 requirements formulated • In 2000, refocused to develop the standards (protocol profiles and related test specs) to enable end-to-end telephony and multimedia communications services over Next Generation Networks

  8. Using IP for Business • Turn users into customers • WHY? • Users do not generate revenue, customers do • SOLUTION • Provide a contract and agree to a level of service (SLA) between the customer and the provider • IMPACT • Network is closed to non-customers • Admission control to distinguish customers from users • Control of QoS to distinguish service that is paid for from one that can be found for free

  9. Business Concerns • Trust Operator should be able to trust the network, Customer should be able to trust the operator • Reliability Customers should find it reliable • Availabilitythe network should always be available • Qualityshould be able to control the Quality of the Service • Accountabilityshould be able to account the use that customers make of the service • Legalityshould be able to comply with laws that apply in the local jurisdiction

  10. Domain 3 Domain 1 Service Domain Service network Client Domain 2 Client Transport Network Transport Network Domains • A usable NGN architecture supports multiple Domains • each Domain may have its own policies • each Domain may have its own commercial goals • and possibly its ownprotocols & transport.

  11. TIPHON Development Process • Service capabilities • Leading to • Conceptual architecture • Implemented using • Meta protocols • Built using • Mappings to signalling protocols • And • NGN protocols (extensions) • Verified by • Protocol testing

  16. Service Capabilities Architecture Data, Semantics & Behaviour Encoding and Mapping Rules Encoding and Mapping Rules Meta Protocol Protocol 1 (e.g. H.323) Protocol 2 (e.g. SIP) INTERWORKING Summary of Approach • Technology independent means of specification!

  17. Validation and Testing • Interoperability is crucial to the success of TIPHONTM technology • Likelihood of interoperability is increased with • Well-defined, accurate and unambiguous standards • Validated standards • Systematic testing of products based on those standards • TIPHON Working Group 6: Validation and Testing • Conformance (compliance) test suites and Interoperability scenarios • good basis for in-house development testing • Interoperability events • Provide feedback to standards

  18. TIPHON status • Release 3 has been completed (10/01) • Lots of new concepts that address the hard problems to unlock opportunities • Better structure for high output delivery • In line with NGN requirements • Future-proof Framework • Business • Architecture • Meta-Protocol • Technology Mapping • Release 4 well underway and Release 5 scope being defined

  22. Conclusion • TIPHON is much more than simply Voice over IP although it does incorporate this • TIPHON is enabling new and differentiated services • Not recreating the ISDN on every technology • TIPHON is technology agnostic where possible • TIPHON does specify capabilities that can be used in real services • Not constrained to specific network technologies • Enables Multi-Interoperability at transport and service level • TIPHON addresses many subjects in common with SPAN • Merger of SPAN and TIPHON required to ensure that ETSI is addressing NGN standards development is an efficient & effective way
