  1. WP6 ProgressReport 6WINIT Project Meeting Basel 10.01.2002

  2. Status and availability of WP6 components………(largely) to be found in…….. • D8 – Description of Basic Network Components • Mobile IPv6 Home Agents • IP Sec gateways (including support for Road Warrior) • Signalling and Media Gateways (SIP and TAG) • WAP Gateways • D9 – Early Aids to deployment • Dual stack networking devices • IPv6/IPv4 tunnelling devices • IPv6/IPv4 translation devices • ALGs Provide updates to - and complements - D2

  3. Deployment (possibly) of WP6 components in 6WINIT Clinical testbeds….to be found in………. • D7 – Description of Implementations of the Clinical testbeds • John Paul II Hospital, Krakow • UKT – GANS scenario, Tuebingen • Whittington Hospital, London *********** WP5 - THANKS !!! ***************

  4. UMM • WAP gateway [Deployed at John Paul II Hospital, Krakow] • Implemented and tested with preliminary password based authentication system • GPRS connectivity has been exploited • Possibly Deployment of other WP6 components • Road Warrior and Dynamical VPN establishment • Mobile IPv6 – MIPL (HUT) on Linux • Socks64 on Linux, possibly DSTM on 6WIND Edge Device (?) • TAG ?

  5. 6WIND Edge Device • Mobile IPv6 Home Agent • Draft –13/-15 (?) • VPN based authentication solution available • IPSec gateway – Dynamic VPN establishment • IKE, certificates [Deployed at UCL-CHIME, UCL + ?] • Firewall • IP filtering [To be deployed at UCL-CHIME, UCL ??] • DSTM, ISATAP • Being developed [Proposed to be deployed at UCL-CHIME testbed + Krakow ?]

  6. IABG FreeS/WAN IPSec implementation [To be deployed at UCL-CHIME + UMM, UKT/RUS testbeds ?] • IPSec Tunnel mode for Gateway to Gateway • IKE with pre-shared keys or RSA • Transport mode for mobile users • SAs are negotiated based on FSDNs Main implementation work completed, now testing. First version available Q1 2002, Fine tuned one Q2 2002

  7. TED • Mobile IPv6 Home Agent [Deployed at IST2001, to be deployed at UKT/RUS Application testbed] • Draft –13 maintained, Moving to draft –15 with • MIPv6 Authentication method (June 2002) • Interworking with IPSec based on HoA(June/fall 2002) • Interworking with IPSec tunnel mode, i.e. VPN solution available • IPv6 over IPv4 access networks solution (e.g. GPRS) • Automatic/configured tunnel solution available (Gateway side) • IPv6 RAs over configured tunnels ready Q2 2002 – Linux patch with tunnel broker available – ERP node from Ericsson Research Finland. • NAT-PT + 6to4 • Ready Q2 2002

  8. BT - ULTIMA [To be deployed at UCL-CHIME testbeds + T-Nova ? ] • Enhanced NAT-PT with DNS - and ftp – ALG • Various other transition mechs • SIP – ALG Functionality is implemented. Continued work with enhanced web based management interface

  9. Gateways and Relaysfor Multimedia Conferencing • ALGs for • Call Signalling Communication • Media Streams • Example Applications • Gateways between call signalling protocols (SIP, H.323) • Gateways between different networks (IPv4/IPv6) • Media Processing (transcoding, mixing) • Application Servers (conference bridges)

  10. Status - TZI-Gateway Components [Proposed to be deployed for audio in GANS scenario ++ ??] • Media processor available as a first prototype • Basic relaying functionality • IPv4  IPv6 • Multicast Unicast • Audio Redundancy (RFC 2198) • Adding audio redundancy to RTP audio streams • Transcoding & mixing currently being implemented • Signalling/control components • Adaptation work in progress • Porting SIP and H.323 modules to IPv6 • H.323 prototype is available • Some infrastructure work has been finished • Mbus • RTP library (with RTP feedback support)

  11. UCL TAG [6WINIT usage scenarios – UMM ???] • Client – Server version available • New features • LAN-LAN reflection • VPN memberships

  12. Technical Issues/Problems • Use of media gateways in 6WINIT • Mobile IPv6 – which draft version – 13, 15 or beyond ? • MIPv6 Authentication method • IP Security • Static VPNs tunnels - no problem • Dynamic VPNs • IPSec and Mobile IPv6 – how far do we go • Other technical issues………….
