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

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?

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

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
![Page 20: Next-Generation Mobility](https://reader035.vdocument.in/reader035/viewer/2022062408/56813b43550346895da41b06/html5/thumbnails/20.jpg)
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
![Page 21: Next-Generation Mobility](https://reader035.vdocument.in/reader035/viewer/2022062408/56813b43550346895da41b06/html5/thumbnails/21.jpg)
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
![Page 23: Next-Generation Mobility](https://reader035.vdocument.in/reader035/viewer/2022062408/56813b43550346895da41b06/html5/thumbnails/23.jpg)
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

• 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
