Networks Research Group Deployment of an IPv6-Enabled Dynamic VPN Infrastructure
Projects Past ANDROID RADIOACTIVE Present 6NET ICB Future SEINIT VPN Technologies Netcelo VPN Manager ISI - X-Bone DRDC - DVC UMU - PBNM Entrust VPN Connector Current Work Networks Research Group Seminar
6NETVPN Infrastructure Deployment “To look at the issues surrounding the provision of IPv6 dynamic VPN technology and deploy an IPv6-Enabled VPN Infrastructure”
International Collaboration Board (ICB) “To carry out an experimental deployment of an IPv6-Enabled VPN Infrastructure upon which one can experiment on the sort of policies that coalition networks require”
Netcelo VPN Management • Deployed During ANDROID • Single VPN Manager • Full Mesh Topology • Tested with Multicast Conferencing • Active Networking (Funnelweb) • Transcoding Active Gateway • Proprietary System Networks Research Group Seminar
ISI X-Bone • UCL extended X-Bone for IPv6 capability during RADIOACTIVE • Overlay Managers & Resource Daemons • Invitation-Based Set-Up • Choice Of Topology • Recursive Overlays • Demonstrated at DANCE - May 2002 • 3 sites - Star Topology • Possibility of sub-optimal topology Networks Research Group Seminar
DRDC DVC • “Provides secure/authenticated out-of-band channels to establish, monitor and dismantle VPNs” • Based On Ideas From X-Bone • Coalition-Based • Full Mesh Topology • Exchange of Security Policies Networks Research Group Seminar
UMU-PBNM • UMU-PKIv6 • CA Provides X.509 Certificate Enrollment And Lifecycle Management for IPv6 • Supports LDAPv6, OCSP and SCEP • UMU-PBNM • Policy Management Tool (PMT) • Policy Decision Point (PDP) • Policy Enforcement Point (PEP) • VPN Enforcement Tool (VPN ETool) COPS Networks Research Group Seminar
Issues • No clear globally accepted VPN definition • Scope of a VPN • Uncertainty in: • What is required • How to develop it • The Current status of each of the projects • VPN Workshop – July 2003 • Aim to discuss and resolve issues of confusion • Aim to encourage collaboration Networks Research Group Seminar
Building An Ideal System • Each system excels in its particular area of focus • X-Bone – Overlay Hierarchy, Topology • DVC – Distributed, Localised Control • UMU-PBNM – Security Infrastructure • Want the best of all worlds Networks Research Group Seminar
Ideal System – Existing Features • Localisation and Security of DVC • Distributed Nature of DVC • Platform Independence of DVC/X-Bone • Hierarchic Nature of X-Bone • Topological Flexibility of X-Bone/UMU • Policy Management of UMU • Security Management of UMU Networks Research Group Seminar
Ideal System – New Features • Dynamic Topology • (Secure?) Routing over VPN • Multicast Capability • QoS Provision Networks Research Group Seminar
VPN Workshop – Summary • X-Bone • Expected to be IPv6-Enabled October • Dynamic Overlay Routing • Node Re-visitation • Provides capability for topological definition • Does not allow addition/deletion of nodes to as existing overlay • Combination with other systems looks promising Networks Research Group Seminar
VPN Workshop – Summary cont. • DVC • Good model for flexible use of policies • Agreed to move to IPv6 – target date November • Currently moving toward XML based policy definition • Discussing combination with UMU Networks Research Group Seminar
VPN Workshop – Summary cont. • UMU • Security Management Infrastructure • Policy Management Infrastructure • VPN definition limited to 6WIND Networks Research Group Seminar
VPN Workshop – Summary cont. • Cisco • Presented various approaches for large scale VPN deployment • Stated IPv6 IPSec solutions not planned before mid-2004 Networks Research Group Seminar
VPN Workshop – Outcome • Updated parties on status of projects • Discussions conducted on problems and issues • Consensus reached over issues of confusion • All parties agreed on collaboration • Plans for hosting a further VPN Workshop during November Networks Research Group Seminar
Future Work • Re-evaluate X-Bone With Enhancements • Initial Deployment Potentially X-Bone • VPN Management System • Dynamic Tunnel Establishment & Management • Dynamic Topology (Bootstrapping) • Policy Definition • Types of policies Networks Research Group Seminar
