Objective of the paperThis research work presents a new IPv4/IPv6 transition method based on MBD-SIIT new technology. Compared with other existing transition methods , the proposed new method is a Multi homing Bidirectional Intelligent Transition System(MBDITS)which deals the intelligent method of transformation and adaptation between IPv4 to IPv6 and vice-versa.

Introduction to the Problem.

The concept of IPv4/IPv6 multi homing transitioning is one of the hot vigorous topic in IPv4/IPv6 Transition.

The Multihoming transition between IPv4 and IPv6 internet will be a very long process as they are completely incompatible two protocols.

Definition of IP.

An IP address is an Identifier that is applied to each device connected to an IP network.

IPv6 Benefits.•Larger address space.

•Expanded routing and addressing capabilities

•Improved support for extensions and optionsFlow labeling(QoS) capabilityServer-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.

IPv6 Transition.

Introduction to Multi homing Concept.Multi homing, is a novel Innovative Concept.Multi homing is the ability of a Host or Site to access remote destinations via more than one upstream connection usually from different providers.Multi homing is a common requirement of many medium-sized networks including many businesses and ISPs.

One reason is for link redundancy allowing a site to retain connectivity when one of the link fails.The other reason is for Optimal use of the links. Ex:-Increasing Bandwidth or QoS factors such as Routing Traffic over the topographically closest link to minimise delay or routing low traffic over the cheapest link.

Fig.1.Multihoming Scenario.

Multi homing scenarios are necessarily always static in nature.The following three example clearly specifies the dynamic nature of multi homing host.A host can acquire additional addresses dynamically(via host renumbering protocol).A Host can acquire additional interfaces dynamically(via tunnel configuration).A Site can acquire additional prefixes dynamically(via router renumbering protocol).

Proposed Methodology•In this paper we proposed a a new Multi homing transition algorithm.•Our new proposed MBD-SIIT(new transition system)depends on the understanding of the received datagram,Capturing the header,Identifying the header,Verification of the header,Transformation of the datagram to the destination environment,and then transmitting the datagram to the destination address.

The MBD-SIIT translator is capable to process each conversion individually,without any reference to the previously translated packets.

An Architecture of MBD-SIIT

An Overall Architecture and Role of MBD-SIIT.

Fig.2.Translation of IPv6 to IPv4 Header.

Role of MBD-SIIT.BD-SIIT resides on an IPv6 host and converts an outgoing IPv6 headers into IPv4 headers, and incoming IPv4 headers into IPv6.

When the IPv6 hosts wants to communicate with an IPv4 host,based on DNS resolution to an IPv4 address,the BD-SIIT algorithm recognizes IPv6 address as an IPv4 mapped-address as shown in Fig.3.

IP Header Translation.

1.IPv4-mapped address (0: FFFF: v4):-This is an IPv6 address simply created by including the IPv4 address of the IPv4 host (v4) with the prefix shown.The BD-SIIT mainly uses this type of address for the conversion of IPv4 host addresses to IPv6

addresses. 2.IPv4 translated addresses(0::FFFF:v4):-According to IETF

specifications this address is created by IPv4 address temporarily assigned to the IPv6-only host and allows for the mapping of the IPv4-translated address of the IPv6 host to an IPv4 address. As the number of globally unique IPv4 addresses becomes scarce, there is a need to take advantage of

Why MBD-SIIT Transition Mechanism.1. To Reduce the Packet size compared with Tunneling Algorithms, in turn, reducing Traffic overhead.

2. 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. 3. Use a New address mapping that depends on identifying two Public addresses(IPv4 and IPv6) instead of IPv4 mapped IPv6 address method.

Performance evaluation metrics and Simulation Parameters.

In this Paper we have calculated three performance evaluation metrics.

1.End to End delay2.Throughput3.Round trip time(RTT) N rec

1.Mean End to End delay= ∑ i=1 EEDi/Nrec

where EEDi = Tdi- Tsi where EEDi is the end to end delay of ith packet. Tsi is the Source packet i created and Tdi is the Destination packet which is

created at Destination. Nrec is the total number of packets received at Dest host and Mean EED is the mean value of each communication session.

The mean throughput for a sequence of packets of specific size is calculated by using equations 1 and 2.

MeanThr = ΣN j=1 Thrj /N -------------(1)

where

Thr=Packetsreceived(Pr)/Packets generated(Pg)*100%.--------------(2)

Where Thrj is the value of the throughput when the packet j is received at

intermediate device like DSTM gateway,BD-SIIT Gateway,v4/v6 Router and N is the number of received packets at intermediate device,Pr is the no of packets received at intermediate device and Pg is the number of packets created by source host.

Simulation Parameters Value

1.Buffer Size 500 Packets

2. Propogation Delay 10ms

3.payload size 200 Bytes

4.Very traffic Load 6~240 Nodes.

5.Queue Management Scheme Drop tail.

Conclusions.

The End to End Delay session of V6-to-V4 Communication is very large as compared to EED of other communication systems.

Throughput of V6-to-V4 communication is Very small as compared to other sessions.
