Agenda

• BT’s IPv6 Group• Home Networking and Mobile IPv6• 3G and Mobile IPv6• Smart v6 Trial• 6WINIT• Questions

BT’s IPv6 Group

• Well-established research group with purpose-built labs and demonstration facilities

• Expertise in all areas of IPv6 development and deployment:– Interworking (Ultima)– DNS– Mobility & 3G systems– Exchanges / Business Modelling– Network configuration and deployment– Application porting / development

• Involved in a variety of internal projects and international collaborative projects

• Autoconfiguration• Always On• Incoming comms for remote home automation• Security• P2P is growing fast• Large numbers of devices

Home networking with IPv6

Home networking & Mobile IPv6(1)

• Without MobileIP, connections from UserA to UserB have to go via ISP A and ISP B

• Inefficient routing• Poor scalability• Multiple single-points-of-

failure

Home networking & Mobile IPv6(2)

• MobileIPv6 provides optimal traffic path

• Only initial traffic is routed through other ISPs point of attachment

• Subsequent traffic routed directly to COA

• Improves scalability

IPv6 in 3G networks

• IM domain is specified IPv6 only in Release 4/5• Are terminals dual-stack or IPv6-only?• Is backbone network dual-stack or IPv6-only?• In time all network elements will migrate to an

IPv6-only solution• Inter-working uses DSTM? NAT-PT?

3G and MobileIPv6

• MobileIPv6 enables seamless roaming between 3G/cellular environment and fixed home/corporate networks

• MobileIPv6 not currently specified in 3GPP

Smart v6 Trial

• Collaboration between BT, SmarTone and Ericsson

• Intended to demonstrate IPv6 applications, IPv6/IPv4 interworking, IPv6 over GPRS, and MobileIPv6 including intelligent content delivery

• Support SmarTone in their bid for a 3G license• 2 day event in Hong Kong October 24th/25th

Smart v6 Trial

• Scenario 1: IPv6-only clients, IPv6-only network running Quake, mp3, Video, WWW

• Scenario 2: Interworking IPv4 and IPv6• Scenario 3: MobileIPv6 and content customisation• Scenario 4: Inter-technology handover

Smart v6 Trial

Smart v6 Trial

• Compaq iPAQ 32MB• OS on Flash ROM• Runs LINUX• Support for WLAN, USB• Developing IPv6 support• Need applications…

6WINIT – IPv6 Wireless Internet Initiative

• EU Fifth Framework project• 18 project participants including US, Korea and

Canada• Aims to build international wireless IPv6

infrastructure and application testbed• Applications: generic and clinical• 2 year project 01/01/01 – 31/12/02• BT will provide network infrastructure and

interworking expertise

Objectives

• Validate introduction of Wireless Internet– Based on IPv6 + GPRS and UMTS/3GPP

• Validate integration of these protocols– in real applications with complete testbeds

• Ensure implementations are generic

• Ensure testbeds not too tied to application

• Maintain international perspective

Testbed Aims

• Carry out in-depth applications in the clinical domain, in hospitals:– Whittington (UK), Tubingen (DE), John Paul II (PL), U. of

Basel (CH)

• Validate specific non-clinical apps– Road Warrior, Seamless wandering, Streaming Media,

Weather station access, M-commerce activities

Specifically Not-Addressed

• Redefinition of air interface• Technologies for the home like ADSL• Re-definition of higher-level appications e.g. HTTP• Development of complete applications• Development of complete IPv6 Stacks• WAP

Clinical Applications

• Exact applications will be identified during first few months, but may be:– Remote Access to haematology database for anticoagulant clinical

management– Ambulance to base communications including A/V and vital data– Remote booking and reservation systems

6WINIT – IPv6 Wireless Internet Initiative

• 24-hour, real-time, emergency tele-consultation staffed with experts in medical crisis management

• Using multimedia equipment to assess the remote patient or treatment problems

• AV streams and vital data will be transmitted from the hospital to the ‘Guardian Angel’ Centre

• The emergency physician will be equipped to communicate with the experts in the ‘Guardian Angel’ Centre

• Extend the stationary scenarios to an ambulance so as to mobilize them

• Assess the remote patient, advise/prepare treatment• AV streams and vital data will be transmitted from the

ambulance to the hospital and possibly ‘Guardian Angel’ Centre
