  1. Bryant Newby English 516 4/26/06 9:30 MWF The Internet “Crisis” - The Transition to IPv6

  2. Road Map • Networking background • What is TCP/IP? • IPv4 problems • IPv6 • Affect on you? • Transitioning technologies • Questions

  3. Layered Networking

  4. What is a Network Protocol? • A communications mechanism • Many flavors • IPX/SPX • OSPF • Big two • UDP • Connectionless • TCP/IP

  5. Internet: TCP/IP • Connection oriented • End to end mechanism • Networking layer • “Loaded” • Protocol suite • Router configuration • End user configuration

  6. Internet Protocol Version 4 • “Fast” • Scalable • Problems: • Complexity • Addressing Scheme • (demo addressing)

  7. Problem • Finite space • 32 bits • Class allocation schemes • Problem scale (crisis?)

  8. Solution - IPv6 • Grand allocation schemes • New technologies • Neighbor identification • QoS • Reduced Complexity • Scalability • Maturity

  9. Version Comparison • IPv4 IPv6

  10. Addressing Comparison

  11. Does it affect you? • Installation • Transparency • Research • Test beds • Transition technologies

  12. Transitioning mechanisms • 6 to 4 • 4 to 6 • DTTS • Expensive

  13. Review • Protocols run computer communication • IPv4 has problems • IPv6 will gradually replace • Transitioning mechanisms will make nearly transparent • Potential problem • YOU might need to address problem.
