6. Thesis Motivation  IPv6 is the proposed way forward to handle the IPv4 exhaustion  There is no other plan B, no other contending alternatives  It has matured in the last two decades  IPv6 is still being treated as an emerging technology  There is a lot of Fear, Uncertainty and Doubt  Its still being considered not matured technology  In the future IPv4 will be taught as legacy technology  Just like Asynchronous Transfer Mode (ATM) and Frame Relay are taucht today  I couldn’t find similar university/academic courses

8. Course Description This course is a laboratory-based course that focuses on the next generation Internet Protocol Version 6. Topics covered include IPv6 Packet Formats, Extension Headers, Unicast Multicast and Anycast addressing, Scoped addressing, various addressing architectures, static and automatic address configuration using DHCPv6 and Router advertisements, Duplicate Address Detection, Neighbor Discovery using ICMPv6, DNS in IPv6 featured such as DNS Server Discovery are covered. Source Routing, Static Routing, Multicast Routing and Dynamic Routing protocols like RIPng, OSPFv3, IS-ISv6, BGP4 are covered. The various transition technologies covered are divided into deploying IPv6 in IPv4 dominant networks and deploying IPv6 dominant networks with IPv4 support. The first category includes tunneling IPv6 in IPv4, like Static Tunneling, 6to4, ISATAP and using Tunnel Brokers. The later includes tunneling IPv4 in IPv6, DSTM and IP Translation. Special topics include Renumbering, Multihoming, Mobility, Security, QoS, Network Management, application porting. (Prerequisite: NSSA 602, NSSA 620) Class 3, Lab 2, Credit 3
9. Course Objectives  Describe the factors that led to the development of IPv6 and uses  Describe the structure of the IPv6 address format  Implement IPv6 services and applications  Understand the updates to IPv4 routing protocols  Identify the best transition mechanism  Describe security issues, and emerging practices for IPv6  Describe the IPv6 address allocation  Identify IPv6 deployment issues  Describe the deployment strategies  Describe case studies for enterprise, service provider, and branch networks
10. Learning Outcomes  describe technologies emerging in the field of networking and system administration and their impact on large organizations  be a key contributing member in the development, management, or research of the computing infrastructure of an enterprise  describe and implement technologies important to the management and deployment of large scale computing environments  interface and communicate effectively at all levels of an organization  design, plan and manage effective computer and network upgrades that meet the operational and business goals of their organizations  participate effectively in research positions, leadership positions, or professional careers in computing in both private and public sectors, or alternatively, for admission to other academic programs
11. Course Goals This course mainly focusses on understanding how IPv6 is different from IPv4. Students who are already be familiar with IPv4 will understand the differences and improvements made to the protocol stack. The students will be working on coming up with a transition strategy while developing a plan, working on steps in executing it and at the same time they will learn of methods to verify the progress of their plan, and to make it more complex, they will understand that they will need to do all this while managing a live network. Henceforth it is important that the students be made aware of the risks and limitations of IPv6. The students completing this course will also learn to eventually migrate their networks from IPv4 to IPv6. Primarily reducing the Fear, Uncertainty and Doubt. Thus making the whole change less intimidating.
12. Course Goals Simplified  This course mainly focusses on  Understanding how IPv6 is different from IPv4  Understand the differences and improvements made from IPv4  How do we get from IPv4 to IPv6 while still keeping the lights on?  Help decide on a transition strategy  Develop a plan and execute it  Verify the plans progress  Understand the risks and limitations of IPv6
13. Course Goals Simplified  This course is targeted towards  network managers  to be network managers  anyone who has a stake in running or operating a network  This course tries to  understand common tasks, follow guidelines, use checklists,  make the transition from IPv4 to IPv6 less intimidating,  use fewer resources than needed  reduce fear, uncertainty and doubt

40. Final Exam Example Question  Why was the Header Checksum filed removed from IPv6, even though it was present in IPv4?  What is the real goal for the OMB federal government mandate for IPv6?  While using IPv4 mapped IPv6 addresses, what is needed to ensure that a client only having IPv4 can communicate with a server only having IPv6?  Is it possible for 6to4 to function with dynamically issued IPv4 addresses via DHCP?
41. Final Exam Example Answer  Why was the Header Checksum filed removed from IPv6, even though it was present in IPv4?  Answer:  The link layer protocol below IP like Ethernet has its own checksum, making another checksum redundant.  The protocols above IP such as TCP and UDP already have a checksum, again making it redundant.  The checksum is optional in UDP over IPv4, but mandatory over IPv6.  The checksum was eliminated to improve router performance, as it needed to have been calculated at each hop.
