Abstract
This work mainly addresses the design a large scale network using dual stack mechanisms. We concentrated on the most imperative theoretical notions of the IPv6 protocol, such as IP addressing, address allocation, routing with the OSPF and BGP protocols and routing protocols performance in dual stack network using GNS3 simulations and Wireshark Network protocol analyzer. It is evaluate a real large-scale network environment utilizing accessible end-to-end estimation methods that focuses on a large-scale IPv4 and IPv6 backbone and made performance the IPv4 and IPv6 network. In this paper, we compiled IPv6 address planning in a large scale network, performance metrics of each network in terms of time sequence graph, round trip time, TCP throughput, TCP connection time and the number of TCP connections per second that a client can establish with a remote server. It is found that, a minor degradation in the throughput of the TCP, TCP response time and a lower packet loss rate are arise in a real large scale dual stack network. We also showed a concise case study on relationship between RTT and network topology, which is cooperative to develop the performance of IPv6 networks. The result shows the proposed scheme for network migration from IPv4 to IPv6 is more reliable than other existing schemes.

In this paper we have focused network migration from IPv4 to IPv6 in a large scale network
Summary
The Internet consists of native IPv4, native IPv6, and IPv4/IPv6 dual stack networks. When both IP versions are available and the users of Internet desire to connect without any limitations, a transition mechanism is mandatory. As IPv4 and IPv6 will co-exist for a long time, this wants the transition and inter-operation mechanism. Due to this cause several transitions mechanisms have been developed that can be used to build the transition to IPv6 efficiently. A number of transition techniques are existing to maintain the connectivity of both IPv4 and IPv6, to accomplish inter connection between IPv4 and IPv6, and support the adoption process of IPv6. In this paper a virtual study of the performance of IPv4-only network with that of dual stack transition mechanism (DSTM) under various types of traffic patterns is accepted out. The analysis makes use of Wireshark graphing capabilities to showed round trip time for ACKs overt time known as a round trip time graph, transmission throughput using TCP sequence numbers called throughput graph, sequence number versus time graphs that help to see if traffic is moving along without interruption, packet loss, or long delays called as time sequence graph Stevens and tcptrace
