  1. IPv6DataTAG Project Meeting25-26 November 2003 Daniel Davids CERN / IT

  2. Summary • Why IPv6 ? • DataTAG IPv6 • Internet2 LSR DataTAG Project Meeting

  3. Why IPv6 ? Shortcomings of IPv4 Advantages of IPv6 • IPv4 Address Space Expansion • Header Format Simplification and • Support for Extensions & Options • Address Auto-Configuration • Designed for P2P Mobility DataTAG Project Meeting

  4. Address Space Expansion 8 8 8 8 128 Class-As of 16,777,216 16,384 Class-Bs of 65,536 2,097,152 Class-Cs of 254 IPv4 A B C D IPv6 3 20 9 16 16 64 0 0 1 Sub- Nets RIR LIR EU Interface /23 /32 /48 /64 /128 Total of 18.4 Exa-Subnets of each 18.4 Exa-Addresses 36,050 Subnets per Square-Meter of Earth’s Surface http://www.ripe.net/ripe/docs/ipv6policy.html DataTAG Project Meeting

  5. CERN’s Allocations • CERN’s IPv4 Address Ranges • 128.141.0.0/16 & 137.138.0.0/16 • This makes roughly 130,000 Addresses • CERN’s IPv6 Address Range • 2001:1458::/32 - LIR Since June 2003 • This makes roughly 4 Billion Sub-Nets DataTAG Project Meeting

  6. Why IPv6 ? Shortcomings of IPv4 Advantages of IPv6 • IPv4 Address Space Expansion • Header Format Simplification and • Support for Extensions & Options • Address Auto-Configuration • Designed for P2P Mobility DataTAG Project Meeting

  7. IPv6 Header & Options • The IPv6 Header Contains the Mandatory Information Fields Version | DiffServ | Flow Label | Payload Length Next Header | Hop Limit | Source | Destination • Optional Information goes into Linked Extension Headers Hop-by-Hop | Destination | Routing | Fragment Authentication | Encapsulating Security Payload DataTAG Project Meeting

  8. Why IPv6 ? Shortcomings of IPv4 Advantages of IPv6 • IPv4 Address Space Expansion • Header Format Simplification and • Support for Extensions & Options • Address Auto-Configuration • Designed for P2P Mobility DataTAG Project Meeting

  9. Address Auto-Configuration • An Interface can receive an IPv6 address from each network it sees • Multiple IPv6 Addresses per Interface • Uniqueness: Use of Pseudo-MAC Address Mobility • Always use the same IPv6 address regardless of the network it sees • It Acquires a Dedicated “Home Address” • Use of Source Routing – Efficient in IPv6 DataTAG Project Meeting

  10. Summary • Why IPv6 ? • DataTAG IPv6 • Internet2 LSR DataTAG Project Meeting
