IP version 6 is a new IP protocol designed to replace IP version 4, the Internet protocol that is predominantly deployed and extensively used throughout the world. The current version of IP has not been substantially changed since RFC 791, Internet Protocol DARPA Internet Program Protocol Specification, was published in 1981. IPv4 has proven to be robust, easily implemented, and interoperable, and has stood the test of scaling an internetwork to a global utility the size of the Internet today. However, the initial design did not anticipate the following conditions:

  • Recent exponential growth of the Internet and the impending exhaustion of the IPv4 address space.
  • Growth of the Internet and the ability of Internet backbone routers to maintain large routing tables.
  • Need for simpler autoconfiguration and renumbering.
  • Requirement for security at the IP level.

  • Need for better support for real-time delivery of data, also called quality of service (QoS).

Note: Features such as IP Security (IPSec) and QoS have been specified for both versions of IP. The session will discus the changes and mechanics between IPv4 versus IPv6 to address the ongoing progress of the Internet.

About the speaker:

Gunter Van de Velde is a Senior Network Consulting Engineer in Cisco's Advanced Services Team. He has been the Technical Team Leader for the IP Core delivery team since early 2001. Gunter received his Master degree in Electronics in 1993. His first professional activities where based on TDMs, modems and L2-bridges. He joined Cisco in 1997, initially providing reactive worldwide support as part of Cisco's Technical Assistence Center (also known as 'Cisco TAC'), specializing in IP Routing protocol technologies. In 1999 he joined Cisco's Advanced Services organization as a Network Consultant, where he has been active in designing large Backbone ISP networks and Services. Since 2001 Gunter has been working as Design Architect for the 6NET IPv6 project. Since then Gunter has been involved in optimizing and supporting the 6NET Infrastructure - his latest project on 6NET is to optimize the overall routing convergence on the 6NET European backbone.
