Hello,

Minutes of the 5th IPv6 Interest Group Meet.

Theme - Mobility & IPv6
Venue - Hotel Nahar Heritage, St. Marks Road,
Date - Friday, 16th May 2002
Time - 5:30 PM to 8 PM

It was a great place to be, it was a treat to be there in a great roof top garden and that too centrally located, As we were having the snacks people started trickling in ! !,  people braving through the heavy traffic came in to attend the meet. we had an exciting evening ahead of us.

Introduction and Welcome - K B Sujith, Advisory Project Manager - Telecom & Media

Sujith welcomed the delegates and enthusiasts to the 5th IPv6 Interest Group meeting.  Stressing on the need and growing demand for mobile data services, Sujith dwelled on the pivotal role of IPv6 in meeting these needs and demands.  Encouraging the forum to act as the nodal point in bringing together the technical community, corporations, government and regulators, he exuded confidence that this would lead to the rapid deployment of mobile data communication services in the country.  He emphasized that IBM is a leading participant in the Internet Engineering Task Force (IETF) and played key roles in the efforts that produced the IPv6 standard. IBM technologists continue to lead in the enhancement of this standard's evolution today. IBM was the first vendor to have an IPv6 enabled UNIX product (AIX) in 1997. IBM is strategically enabling key products with IPv6 capability to meet demands of the next generation Internet, demonstrating its leadership and commitment to IPv6 enablement worldwide.

Admitting that he held a close watch over the activities of the IPv6 Forum India, offered his appreciation for its activities.  He wished the forum continued success and urged it to strive towards ushering in the mobile datacom revolution in the country.

Mobility in IPv6: Motivation, Featues and Challenges - Sabarinath VN, IBM Global Services

The demand for mobile data communication from businesses, law enforcement and emergency service providers has been growing. Lately, personal data communication requirements have also increased. The advent of intelligent portable devices coupled with advances in battery technology and the widespread deployment of wireless networks has provided a fertile breeding ground for mobile data communication.Mobility can be realized at the Data Link layer and the Network layer. The Network layer approach has proven to be more robust and efficient in comparison to the former. IP being the universal network layer protocol is the natural choice for network layer mobility.

Mobile IP creates a tunnel between the Home Agent (a router on the home network) and the Mobile Node. The HA accepts all packets destined for the MN and tunnels them to the MN, while the MN is away from it's home network. Datagrams originating at the MN, may be delivered directly to the recipient. Mobile IPv4 suffers from several drawbacks - triangular routing being the most prominent. IPv6 with it's seemingly unlimited public addresses, inbuilt IPSec and auto-configuration provides solutions for almost all IPv4 drawbacks. Drawbacks to Mobile IPv6 exist. Several solutions have been proposed and are being debated today.The presentation concludes that Mobile IPv6 is the best approach to manage mobility in multi-access networks. It is also the most feasible method forproviding public addresses to mobile data terminals. The world today is at the threshold of a major communication revolution. Mobile Data Communication and

the potential it promises to unleash is of a magnitude seldom experienced.

Mobility support in IPv6 with Demonstration - Mr. Anil Bhaskarwar - Wipro Technologies

The lecture starts with the demonstration. The demonstration on Mobile IP was a video shoot in the lab, where how Mobile IP and authentication part of it was exhibited. The details of the demo is as follows:

• Showcased the binding table and visitor table when mobile node is in the home subnet
• Showcased the binding table and visitor table when mobile node is in the foreign subnet.
• Also showcased the routes that Home agent learned when mobile node in the foreign subnet
• How then Mobile node sends the route details to other subnets.
• Showcased how security is maintained by handshaking the private key

The demonstration was followed by the presentation, which described how actually it was been accomplished. The presentation described step by step how such solution can be provisioned. Also the advantages of the solution, its current trends, the future trends, and business drivers.

The second presentation was on the Mobility Support in IPv6 Protocol with demonstration. Following mobility support were discussed.

• Absence of Foreign Agent
• Ingress Filtering V/S Home Agent Destination option in IPv6
• Route Optimization
• Routing Header extension header

At last, Current Issues in Mobile IPv6 and where Mobile IPv6 can be used were summarized

Hierarchical Mobile IPv6 mobility management  - RFC Discussion - Mr. Praveen Rajendran, Samsung India.

"Hierarchial Mobile IPv6 introduces extensions to Mobile IPv6 and IPv6 Neighbour Discovery to allow for local mobility handling. Hierarchical mobility management for Mobile IPv6 reduces the amount of signalling between the Mobile Node, its Correspondent Nodes and its Home Agent.

 
The presentation presents an overview of HMIPv6 and introduces the various components. It then presents the mechanism of signalling in HMIPv6 and discusses its hierarchial manner of grouping. It then presents some advantages and disadvantages including how the Mobility Anchor Point can also be used to improve the performance of Mobile IPv6 in terms of handoff speed."
