Road Map
● Background on Networking● What is TCP/IP?● IPv4 problems● IPv6● Affect on you?● Transitioning technologies● Questions
![Page 3: The Internet “Crisis” - The Transition to IPv6](https://reader036.vdocuments.mx/reader036/viewer/2022062804/568148f7550346895db617db/html5/thumbnails/3.jpg)
Layered Networking
![Page 4: The Internet “Crisis” - The Transition to IPv6](https://reader036.vdocuments.mx/reader036/viewer/2022062804/568148f7550346895db617db/html5/thumbnails/4.jpg)
What is a Network Protocol?
● A communications mechanism● Many flavors
IPX/SPX OSPF Big two
● UDP Connectionless
● TCP/IP
![Page 5: The Internet “Crisis” - The Transition to IPv6](https://reader036.vdocuments.mx/reader036/viewer/2022062804/568148f7550346895db617db/html5/thumbnails/5.jpg)
Internet: TCP/IP
● Connection oriented● End to end mechanism● Networking layer● “Loaded”
Protocol suite Router configuration End user configuration

Internet Protocol Version 4
● “Fast”● Scalable● Problems:
Complexity Addressing Scheme
![Page 7: The Internet “Crisis” - The Transition to IPv6](https://reader036.vdocuments.mx/reader036/viewer/2022062804/568148f7550346895db617db/html5/thumbnails/7.jpg)
IPv4 Addressing
● What is addressing? Demo
● Problems Finite space
● 32 bits Class allocation schemes
● Problem scale
![Page 8: The Internet “Crisis” - The Transition to IPv6](https://reader036.vdocuments.mx/reader036/viewer/2022062804/568148f7550346895db617db/html5/thumbnails/8.jpg)
Internet Protocol Version 6
● Grand allocation schemes● New technologies
Neighbor identification QoS
● Complexity reduced Scalability
● Maturity

Comparison
● IPv4 IPv6

Addressing Comparison
IPv4 IPv6
Raw # 2 ̂ 128
In use 1.4 billion
Reserved 1.4 billion
Available 1.4 billion
4.3 billion (2̂ 32)

Does it affect you?
● Installation● Transparency● Research● Test beds● Transition
technologies

Transitioning mechanisms
● 6 to 4● 4 to 6● DTTS● Expensive

Review
● Protocols run computer communication● IPv4 has problems● IPv6 will gradually replace● Transitioning mechanisms will make
transparent● Potential problem if not addressed● YOU might need to address problem.
