IPSec overhead analysis in dual stack IPv4/IPv6 transition mechanisms

Internet Protocol version 4 (IPv4) is the current IP in use at the backbone of the Internet. Internet protocol version 6 (IPv6) is proposed to succeed IPv4 by IETF. IPv6 addresses among other issues the lack of security in IPv4 at network layer, in IPv6 this is addressed by the use of Internet protocol security (IPSec). This research reports on the evaluation of IPSec in an IPv4/IPv6 dual stack network
