Performance Eveluation of IPv4 and IPv6 Networks in Absence of Link Layer Protection
This paper evaluates the performance of IPv4 and IPv6 networks in the absence of link layer protection. Behavior of both the networks has been discussed and simulated in case of ideal scenario, low noise, medium noise, high noise and very high noise environment. Transmission behavior at each router is observed and computed to understand the comparative performance of IPv4 and IPv6 datagram's. The authors' simulation results for throughput, transmission time, number of corrupted packets and number of retransmissions clearly indicates that IPv6 performs better in ideal and low noise scenario as there is no checksum computed at each router and number of retransmissions for corrupted packets are also less.
