Performance of intra and inter communications of IPv4-in-IPv6 tunneling mechanisms
2014
In order to reach the customers thoroughly, internet contents need to support both IPv4 and IPv6. In this case, ISPs should provide their customers with IPv4 and IPv6 access seriously until the IPv4 is disabled eventually. Each transition solution needs to concern not only high working performance but also network supporting in the future. This paper investigates the performance of various transition schemes; IPv4 Residual Deployment across IPv6-Service networks (4rd), 4over6, Lightweight 4over6 (Iw4over6) and Enhancement of Lightweight 4over6 (elw4over6). Computer simulations are divided into two scenarios: intranet (intra-communication) and internet (inter-communication) based on the following performance metrics: CPU utilization, HTTP traffic received, HTTP traffic lost and HTTP object response time. We have found that elw4over6 is the best one for the networks that require flexibility of IP address allocation and providing good quality of IPv4 connectivity.
