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.
