  1. UCL Overview of VPN Work

  2. Projects Past ANDROID RADIOACTIVE Present 6NET ICB VPN Technologies Netcelo VPN Manager ISI - X-Bone DRDC - DVC UMU - PBNM Entrust VPN Connector Current Work VPN Workshop

  3. ANDROID • Netcelo IPv6 VPN Manager • Full Mesh Topology • Active Network Techniques • Funnelweb • Transcoding Active Gateway VPN Workshop

  4. RADIOACTIVE • ISI X-Bone • UCL extended X-Bone for IPv6 capability • Demonstrated at DANCE - May 2002 • 3 sites • Star Topology • Possibility of sub-optimal topology VPN Workshop

  5. 6NETVPN Infrastructure DeploymentWork Package 4 - Activity 4.3 “To look at the issues surrounding the provision of IPv6 dynamic VPN technology and deploy an IPv6-Enabled VPN Infrastructure”

  6. 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”

  7. UCL IPv6 VPN Deployment Requirements • IPv6-Enabled • VPN Management • Security Infrastructure • Policy Infrastructure • Non-Fully Meshed Topology • Failure Tolerant • Deployable Over Multiple Platforms VPN Workshop

  8. Future Requirements • Topology • Flexible • Dynamic • Routing • Dynamic • Secure • Multicast • QoS VPN Workshop

  9. 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 VPN Workshop

  10. Ideal System – Existing Features • Localisation and Security of DVC • Distributed Nature of DVC • Wide Deployability of DVC/X-Bone • Hierarchic Nature of X-Bone • Topological Flexibility of X-Bone/UMU • Policy Management of UMU • Security Management of UMU VPN Workshop

  11. Ideal System – New Features • Dynamic Topology • Secure (Non-Decrypted) Routing over VPN • Multicast Capability • QoS Provision VPN Workshop

  12. Issues • Definition of a “VPN” • Scope – Edge vs. Node • VPN Management System • Central / Coalition / Combination • Dynamic Tunnel Establishment • Tunnel Management • Minimised Overheads VPN Workshop

  13. Issues (cont.) • Security • Authentication • PKI Infrastructure • Certificate Enrolment & Management • Authorisation • Distributed Access Control • Policy Management • Automated Policy Negotiation VPN Workshop

  14. Issues (cont.) • Topology & Routing • Ability To Choose Topology • Dynamic Topology • Requires Dynamic Routing • Bootstrapping • Secure Routing VPN Workshop
