Assessment of IPv4 and IPv6 Networks with Different Modified Tunneling Techniques using OPNET

Abstract

Currently, all the devices are using Internet protocol version 4 (IPv4) to access the internet. IP addresses of the IPv4 are now depleted from IPv4 pool announced by IANA (Internet Assigned Number Authority) in February 2011. To solve this issue Internet protocol version 6 (IPv6) is launched. But the main problem is current devices can't support directly IPv6 that causes various compatibility issues. Many researchers have proposed various techniques, but still, their efficiency and performance is a big challenge. This study examines several mechanisms of transition IPv6 the backbone of multiprotocol label switching (MPLS) to evaluate & compare their performances. It involves comparing different performance metrics and manual tunneling tunnel efficiency metrics. The main goal of this paper is to examine the dissimilar tunneling techniques and find out which tunneling method is better in all performance, which increases network performance. Experimental results show that ISATAP is better performance in all metrics.

Performance Comparison Between Different Tunneling Techniques Using Different Routing Protocols

“…The IPv4 and IPv6 MPLS network were configured using the customer edge and supplier edge routers. It was found that ISATAP PE had minimum jitter and high throughput, whereas GRE CE had the lowest throughput and high jitter [53]. In 2020, M. A. Naagas et al used the Dual-stack, IPv6 only, IPv4, 6to4 tunnel broker mechanisms.…”
