IPSec Overhead in Dual Stack IPv4/IPv6 Transition Mechanisms: An Analytical Study

Abstract

Internet protocol version 6 (IPv6) is the next generation Internet protocol proposed by the Internet Engineering Task Force (IETF) to supplant the current Internet protocol version 4 (IPv4). Lack of security below the application layer in IPv4 is one of the reasons why there is a need for a new IP. IPv6 has built-in support for the Internet protocol security protocol (IPSec). This chapter reports work done to evaluate implications of compulsory use of IPSec on dual stack IPv4/IPv6 environment.
