6WINIT Project Meeting, BASEL K. Egede Nielsen/TED Research 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 !!! ***************

6WINIT Project Meeting, BASEL K. Egede Nielsen/TED Research 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 ?

6WINIT Project Meeting, BASEL K. Egede Nielsen/TED Research 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 ?]

6WINIT Project Meeting, BASEL K. Egede Nielsen/TED Research 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

6WINIT Project Meeting, BASEL K. Egede Nielsen/TED Research 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 Q – Linux patch with tunnel broker available – ERP node from Ericsson Research Finland. NAT-PT + 6to4 –Ready Q2 2002

6WINIT Project Meeting, BASEL K. Egede Nielsen/TED Research 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

6WINIT Project Meeting, BASEL K. Egede Nielsen/TED Research 9 Gateways and Relays for 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)

6WINIT Project Meeting, BASEL K. Egede Nielsen/TED Research 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)

6WINIT Project Meeting, BASEL K. Egede Nielsen/TED Research 11 UCL TAG [6WINIT usage scenarios – UMM ???] Client – Server version available –New features LAN-LAN reflection VPN memberships

6WINIT Project Meeting, BASEL K. Egede Nielsen/TED Research 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………….
