An Enhancement of IPv4-in-IPv6 Mechanism
2014
From global Internet information, IPv6 traffic grows slowly. A large portion of service providers are still using IPv4 even IPv6 co-exists with IPv4 for long time. However, IPv6 traffic are gradually growing especially most of network backbone sides. This paper proposes an enhancement mechanism of IPv4-in-IPv6 which supports IPv6 natively and provides IPv4 connectivity by using IPv4-in-IPv6 tunneling, so called "Lightweight 4over6 (lw4over6)". The performance metrics used in this evaluation are: system throughput and packet dropped. Based on our computer simulation results, when the system has a mix of intra and inter-communications, we have found that, with light traffic load, the proposed method performs better than lw4over6 and 4over6 slightly. However, with more heavy traffic load the proposed method gives higher performance than lw4over6 significantly.
