    2. 2. Under the Supervision of : Dr.Manjaiah.D.H. Chairman and Associate Professor, Dept of CS,Mangalore University, Mangalore . Research Candidate : Hanumanthappa.J. Senior Asst.Professor , DoS in CS,UoM,MGM,Mysore-06. Compare and Contrast between NAT-PT and BD-SIIT Translators in Transition of IPv4 to IPv6 . 01/28/11
    3. 3. Presentation Outline . <ul><li>Objective of the paper. </li></ul><ul><li>Introduction to the problem. </li></ul><ul><li>Data sets used. </li></ul><ul><li>Proposed Methodology. </li></ul><ul><li>Results. </li></ul><ul><li>Conclusions. </li></ul><ul><li>References . </li></ul>01/28/11
    4. 4. Objective of the paper . <ul><li>This research work presents a new IPv4/IPv6 transition method based on the Comparison and Contrast between Stateless BD-SIIT and Stateful NAT-PT Translators in Transition of IPv4 to IPv6 new technology . </li></ul><ul><li>BD-SIIT and NAT-PT Translators are Powerful Translators in IPv4 to IPv6 Transition . </li></ul><ul><li>BD-SIIT Performance is really good as compared to NAT-PT Translator. </li></ul>01/28/11
    5. 5. Introduction to the Problem . <ul><li>The concept of IPv4/IPv6 transitioning is one of the hot vigorous topic in IPv4/IPv6 Transition . </li></ul><ul><li>The transition between IPv4 and IPv6 internet will be a very long process as they are completely incompatible two protocols . </li></ul>01/28/11
    6. 6. Definition of IP . <ul><li>An IP address is an Identifier that is applied to each device connected to an IP network . </li></ul>01/28/11
    7. 7. IPv6 Benefits . <ul><li>Larger address space. </li></ul><ul><li>Expanded routing and addressing capabilities </li></ul><ul><li>Improved support for extensions and options </li></ul><ul><li>Flow labeling(QoS) capability </li></ul><ul><li>Server-less Auto-configuration(Plug and Play), Reconfiguration and Neighbor discovery(ND) </li></ul><ul><li>Authentication and privacy capabilities. </li></ul>01/28/11
    8. 8. <ul><li>Simple transition from IPv4. </li></ul><ul><li>Built in Strong IP-layer Encryption,Decryption and Authentication . </li></ul><ul><li>Real time applications like Video & Audio. </li></ul><ul><li>More efficient and Robust mobility mechanisms. </li></ul><ul><li>Improved support for options and extensions. </li></ul><ul><li>Streamed Header format simplification . </li></ul>01/28/11

    10. 10. Transition to IPv6: Design Goal <ul><li>No “flag” day. </li></ul><ul><li>Incremental upgrade and deployment. </li></ul><ul><li>Minimum upgrade dependencies. </li></ul><ul><li>Interoperability of IPv4 and IPv6 nodes. </li></ul><ul><li>Let sites transition at their own pace. </li></ul><ul><li>Basic migration tools </li></ul><ul><ul><li>Dual stack and tunneling </li></ul></ul><ul><ul><li>Translation </li></ul></ul>
    11. 11. Transition Mechanisms:Dual Stack <ul><li>New nodes support both IPv4 and IPv6. </li></ul><ul><li>Upgrading from IPv4 to v4/v6 does not break anything. </li></ul><ul><li>Same transport layer and application above both. </li></ul><ul><li>Provides complete interoperability with IPv4 nodes. </li></ul>
    12. 12. Figure-2:Dual Stack
    13. 13. <ul><li>Tunnel IPv6 packets across IPv4 topology. </li></ul><ul><li>Configured tunnels: </li></ul><ul><ul><li>Explicitly configured tunnel endpoints. </li></ul></ul><ul><ul><li>Router to router , host to router. </li></ul></ul><ul><li>Automatic tunnels: </li></ul><ul><ul><li>Automatic address resolution using embedded IPv4 address (like IPv4-compatible address). </li></ul></ul><ul><ul><li>Host to host, router to host. </li></ul></ul>

    15. 15. Translators in IPv6. <ul><li>BD-SIIT Translators. </li></ul><ul><li>NAT-PT Translators . </li></ul>01/28/11
    16. 16. Operation of BD-SIIT <ul><li>V4-V6 DNS(DNS46) server determines two public IPv4 and IPv6 addresses which are statistically or dynamically exist for IPv4/IPv6 communication system. </li></ul><ul><li>V4-V6 Enabled Gateway which performs address mapping between IPv4 and IPv6 addresses as well as IPv4 and IPv6 header conversion. </li></ul>
    17. 17. Figure-6: BD-SIIT Translation Process.
    18. 18. Figure-7: Translation of IPv6 to IPv4 Header Translation of IPv4 to IPv6 Header .
    19. 19. Why BD-SIIT Transition Mechanism <ul><li>To reduce the packet size compared with Tunneling Algorithms, in turn, reducing traffic overhead. </li></ul><ul><li>Reduce the cost of IPv6 Network by avoiding the need to upgrade all the edge nodes that support both the IPv4 and IPv6 as found in Dual Stack mechanisms. </li></ul><ul><li>Use a new address mapping that depends on identifying two Public addresses (IPv4 and IPv6) instead of IPv4 mapped IPv6 address method. </li></ul>
    20. 20. Figure-8: BD-SIIT Data packet Transmission Process
    21. 21. BD-SIIT Translation mainly occurs due to the following Stages <ul><li>Stage 1: IPv6 Packet Transmission. </li></ul><ul><li>Stage 2: IPv6-to-IPv4 mapping calculation and address mapping. </li></ul><ul><li>Stage 3: IPv6-to-IPv4 Header Translation. </li></ul><ul><li>Stage 4: IPv4 packet Transmission. </li></ul>
