The 21 st Century Network Standards Requirements Keith

The 21 st Century Network Standards Requirements Keith Dickerson Head of Standards BT Group

Agenda • Why a 21 st Century Network? • What does a 21 st Century Network look like? • What new Standards are required? • What do ITU and fora need to do?

Why a 21 st Century Network? • Make it easier to create new services – Faster – More people can create • Make it easier to buy and use services – Enable customers • Make it simpler to deliver and maintain service – Process automation • 30 -40% cost reduction

What does it mean? • New services – Open APIs and applications platforms – Mobile enabled – Re-usable components/capabilities – Build on broadband • Cost reduction – Not enough to do efficiencies and automation – Radical network convergence to fewer networks and systems carrying more services – Converge in from the edge

21 st Century Services Vision “A world where all our customers feel empowered and are treated as individuals”

New Services (1) Multimedia calling (SIP) Broadcast TV • Vo. IP, video, Instant messaging, photos, movies, sharing, games Gaming • • Video Downloads • • 4. 7 Gbyte DVD can be stored on CD Could be streamed (nrt) in ~3 hours Microsoft XBox will become a STB Digital Rights Management? Wholesale Broadcast TV distribution service Only available to BB Customers Teleworking Biplay service (or tri-play) Services integrated by CPE (or by SP) Security • • • Low latency downloading QOS management • • Virus scanning Firewalls Back-up Encryption • • • Remote LAN access Security / encryption Roaming

New Services (2) • Broadband – Move from selling best effort pipe to assured services charged per session/time/ – Provide one way assurance (VOD, Turbo button etc) but also twoway multimedia calling – Allow anyone to create services • Business – Provide ICT service, managed desktop, storage, hosted applications… Build on IPVPN to have any access, including work at home, cellular and WLAN • Future voice – Derived/replacement where needed – Multi-media in both consumer and business • Mobility – Support mobile terminals – Build on IM/mobile presentation to provide roaming over any access – Personal and terminal mobility

Cost Reduction • Efficiencies and automation not enough – need to enable customers and partners in the service management processes • Have to include future of PSTN (voice) • Radical steps required – need closure of legacy networks and systems • More important to converge in access and backhaul than in core – because opex and capex centred there

Application Architecture

Example Architecture Implementation

Highest Priority 21 CN Standards Requirements • 3 GPP Architecture extended to WLAN and fixed Broadband access • Qo. S – MPLS (Session) based Qo. S • Session Control – extensions to SIP with full multimedia capability • Manageability – Commoditised componentised OSS • Security – Authentication across networks / operators

ITU is important to 21 CN for: • • • Access Networks – SG 15 Core Networks – SG 13 Optical Networking – SG 15 Spectrum – ITU-R Numbering & Addressing – SG 2 Signalling for Qo. S across multiple networks – SG 11 • Qo. S Architecture in SG 16?

Important Fora for 21 CN • • 3 GPP – Mobility Architecture IETF – IPv 6, SIP extensions, MPLS, etc TMF – standardised OSS components Open Mobile Alliance (OMA) – (Mobile) Applications, DRM Metro Ethernet Forum (MEF) – Gigabit Ethernet IEEE 802. 11 x - WLAN W 3 C – Privacy, Web Services Liberty Alliance – Single Sign On

Conclusions • 21 st Century Network will only succeed based on standardised components • ITU must work with fora and consortia to achieve standards for 21 CN • ITU-T Informal Forums Summit (IFS) must lead way
