  • 13. What Next?Saturday, May 19, 12
  • 14. Think about changeSaturday, May 19, 12
  • 15. “By 2015, 17% of global Internet users will be IPv6, with 28% of new Internet connections running the protocol.” Gartner, Dec 2010Saturday, May 19, 12
  • 16. The World is Changing 17% 419,000,000 Users (based on 2011 data)Saturday, May 19, 12
  • 17. Saturday, May 19, 12
  • 18. AddressesSaturday, May 19, 12
  • 19. 340 282 366 920 938 463 463 374 607 431 768 211 456Saturday, May 19, 12
  • 20. How Big? 340 282 366 920 938 463 463 374 607 431 768 211 456 undecillion decillion nonillion octillion septillion sextillion quintillion quadrillio n trillion billion million thousandSaturday, May 19, 12
  • 21. Subnet Size — Subnets should always be /64 — Many vendors assume 64 bit boundary — 18.4 quintillion addresses per subnet — Perspective: — 31.5M seconds per year — 2.4 B seconds in average lifetime IPv6 Address Address Prefix Interface IdentifierSaturday, May 19, 12
  • 22. Address TypesSaturday, May 19, 12
  • 23. Local Link Address — Bound to local network — Non routable — Automatically configured — Uses MAC address to create unique address — Multi-homed devices use “Zones” LocalSaturday, May 19, 12
  • 24. Unique Local — Private within organization — Similar to RFC 1918 — Routable within organization — 40-bit pseudo-random number for uniqueness — Stateful or Stateless allocation — Can be tunnelled Unique Local LocalSaturday, May 19, 12
  • 25. Global Unicast — Globally unique — Public address space — 42 Undecillion address available — Prefix allocated by RIR/ISP — Stateful or Stateless allocation Global Unicast — Provides peer-to-peer connectivity Unique Local LocalSaturday, May 19, 12
  • 26. More Than AddressesSaturday, May 19, 12
  • 27. Extension Headers — IPv6 Uses simplified header — Chains additional headers onto one another — QoS, IPsec, TCP, UDP and other protocols implemented as “extension” headers — Protocol can be extended — Future friendly IPv6 Header Version Traffic Class Flow Label Payload Length Next Header Hop Limit Source Address Destination AddressSaturday, May 19, 12
  • 28. Neighbour Discovery — Uses link layer for auto configuration of nodes — Provides “plug-and-play” network functionality — Performs: — Router discovery — Prefix discovery — Address resolution — Parameter discovery — Duplicate address detectionSaturday, May 19, 12
  • 29. Path MTU Discovery — Based on IPv4 feature present in many routers — Functionality moved into core protocol — IPv6 does not like fragmentation — Right-sizes MTU for optimized transmission — Performed dynamically — Increased throughputSaturday, May 19, 12
  • 30. Multicast — Fundamental shift from IPv4’s broadcast mechanism — Broadcast not part of IPv6 — Allows networks to scale larger than IPv4 — Puts emphasis on the router rather than the switch — Can be used to discover services — Used by DHCP6 and other protocolsSaturday, May 19, 12
  • 31. Mobile IP — Documented in RFC 6275 — Allows forwarding of traffic from a “care of” address — Maintains session when joining new networks — Still experimental status — Currently complicated to implement — Will become more important as everything becomes mobile — LISP might be better alternative for someSaturday, May 19, 12
  • 32. Quality of Service (QoS) — Greater flexibility for managing QoS — Implemented as an extension header — Currently QoS in IPv6 is same as IPv4 — Has ability to provide better flow control — Future implementations will utilize more effectivelySaturday, May 19, 12
  • 33. IPsec — Part of core protocol — Developed in conjunction with IPv6 — Applications to provide VPN functionality — Implemented as extension header — Changes security in IPv6 — Encrypt IPv6 tunnelsSaturday, May 19, 12
