Evaluation of the Performance of an IPv6 network using IPSec in Tunneling Mode

Abstract

IPv4 address space is about to reach its limit and could collapse. To correct this event, many propose that existing networks should make the definitive migration to IPv6, taking as a reference that this protocol will allow a larger IP address space, providing new opportunities and correcting the existing problems in the protocol of the previous version. However, due to the increased overhead in IPv6 and its interaction with edge routers and operating systems that host this communication protocol, network performance problems can obviously occur. This article is based on a quantitative research using a method that allows analyzing the performance of networks based on IPv6 with IPSec using simulation with GNS3, with this tool compares results with three typical scenarios of implementation in relation to the original topology of this work, Its evaluation determines the difference in performance between scenarios when traffic is generated from one network to another and a scenario with better stability and performance is obtained from among them using an experimental methodology, with which we will be able to verify that its counterpart scenario with the use of tunnels is more optimal in relation to the one proposed in this research, taking into consideration that the metrics analyzed are bandwidth, latency and jitter.
