Objective of the Problem . In this paper we proposed a new algorithm called BD-SIIT RST which depicts the structure of the algorithm called reduction tree designed based on the entries in the routing table using portion(section)division using an algorithm . As a challenge for future simulations we have identified the design of a Novel reduced segment table using BD-SIIT Divide-and-Conquer based IPv6 Address Longest Prefix Matching . 4/13/2011

4/13/2011 Definition of IPv6 . IPv6 is the Internet’s next-generation Protocol. The First name of IPv6 is IPng . The IETF developed the basic Specification’s during the 1990’s to support a migration to a new development . IPv6 is defined in RFC 2460 Internet Protocol version 6 Specification by S. Deering and R.Hinden(December 1998).

Introduction Larger address space. Expanded routing and addressing capabilities. Improved support for extensions and options. Flow labeling(QoS) capability. Server-less Auto-configuration(Plug and Play). Reconfiguration and Neighbor discovery(ND). Authentication and privacy capabilities . Simple transition from IPv4. Built in Strong IP-layer Encryption, Decryption and Authentication . Real time applications like Video & Audio. More efficient and Robust mobility mechanisms. Improved support for options and extensions. Streamed Header format simplification. 4/13/2011
