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 Research5

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 Research6

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 Research7

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

6WINIT Project Meeting, BASEL K. Egede Nielsen/TED Research8

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 Research9

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)

6WINIT Project Meeting, BASEL K. Egede Nielsen/TED Research10

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 Research11

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 Research12

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………….
