Goals

1. To analyse the TIPHON environment To guide further growth of TIPHON To ammend the working methods and procedures Goals

2. Network Capacity Planning Discontinuity Voice Dominated Networks Data Dominated Networks Worldwide voice/modem traffic • Projected Actual ç Source: Internet Society

3. 25 700,000 IETF introduces HTML 2.0, making user-friendly browsers possible CCITT Group 3 fax standardized, making global interoperability possible 600,000 20 Commercial browser available 500,000 Number of WWW Servers Group 3 fax terminals available in market 15 Fax terminals installed base (millions) 400,000 300,000 10 200,000 5 100,000 0 0 Dec 93 1980 Dec 94 Dec 95 Dec 96 1985 1990 1995 Standards Grow Markets - two examples Fax Internet “Standards are the DNA of the Internet” Compaq ETSI High-level Consultative Meeting Moscow, September 1999 Mocow, E.

4. Operators’ Rating of Drivers for Voice over IP average of all surveyed operators not important very important 1 2 3 4 5 6 Offering new and advanced services Cost savings through efficiency of unified network Cost savings through more bandwidth efficiency VoIP as an additional, low-cost service Market pull from business customers Avoidance of interconnection cost Growing competitive pressure through VoIP Market pull from residential customers Offloading peak traffic from the trad. voice n/w Improved customer retention (for ISPs only) Charge usage-based instead of flat rate (for ISPs only) Interview basis: 16 Operators’ Motivation to Deploy VoIP Services

5. Business environment 5/97 • Start-ups • first feasibility • low-bitrate/low-cost service • first interop problems • Internet as free resource • proprietary solutions and single standard • PC/PC 12/99 • large operators and vendors • mergers/aquisitions • managed IP networks • multiprotocol environment • CATV, DSL, always on IP as access • network integration and flexible services

6. Standards environment 5/97 • Single standard H.323 • decomposition of switches starts • Telephony a no-no word in IETF • SIP first versions for MM 12/99 • multiple standards • H.323 + annexes • SIP + DCS • MGCP/SGCP • SS7 + IP coexist. • telephony is mainstream in IETF • SIP has become complex • major topic for ETSI, 3GPP

7. Survey#15 results

8. Lack of efficiency, loosing vision, loosing focus***, & market position poor quality of documents very slow little “original work” far from original scope (interworking), too many  issues (too much debate of the wrong type) Liaison process doesn’t work, lack of harmonization with other Std bodies (invite experts rather than send a doc) not oriented towards service providers Anonymous survey results: TIPHON in general

9. Should be more active, and effective Lack of strong management Lack of a technical steering group PMC members have  agendas TIPHON Chairman should use his power to keep TIPHON focused Composition of PMC doesn’t represent TIPHON community Anonymous survey results: PMC

10. Achievements TIPHON • The industry (vendors, operators, service providers, ...) is our customer (Question to answer: did TIPHON enable new businesses for its participants?) • Tangible achievements • deliverables • rather harmonized approach in various bodies, e.g. SG 16, T1, TIA, IMTC, IETF provides development security • Spin offs: TTT-Net/-services and TIPIA/aHit! lead to deployment • The Validation Portfolio • Interoperability events speed up development • virtual interop to save travel costs

11. Goals TIPHON, general • Maintain global acceptance by intensified cooperation esp. with ANSI T1, TIA, IETF, ITU-T, TTC and 3GPP • Strengthen our position in validation by • ongoing engagement in InterOps/SuperOps • branding of cyber-interop • Evolution of work areas and working methods according to increased market maturity • Increase commitment of the operatorsaHit! and TTT-Services

12. Goals • To specify a system to provide a Basic Telephony Service over IP for public offering essentially equivalent to ISDN Telephony service which is open to extended applications • To maintain leadership in architecture and to provide guidance to ITU-T, 3GPP and IETF • To apply a system-wide approach for security, name resolution, management and guaranteed QoS • To enable systems integration by profiling of protocols and security mechanisms • To define extensions to architecture, QoS, security to support mobility • To reduce ambiguities in protocols

13. Proposals for change • Apply formal methods and a staged top down approach based on ISDN service description for basic service only • Apply procedures/architectures for service enhancements • Approve new work items after 4 weeks on the server after critical consistency check • Apply rigorous project management and allow for “friendly dictatorship” (check new WIs, provide consistency, clear priorities) • Empower editors into the driving seat with interims meeting • Harmonize SIP and H.323 as call control protocols to support a generic information flow • Technical Steering Group tbd.

14. Actions WG1: Identify the appropriate formal staged approach (Service description, architecture and information flows, protocol selection and design) WG2: Identify procedures/arch. for service enhancements chair: invite SIP experts to BoF in March 2000 chair: implement approval process for new WIs SO: to implement project management WG7 chair: contribute TIPHON architecture to 3GPP core network chair/VCs: hold IP Telephony standards summits PMC/secr.: Communicate finalisation of release 1&2 via brochure, press etc.
