| Summary: | The contemporary Internet that we have been using today is based on Best-Effort (BE) service only,
where packets are assigned and forwarded with the same priority. The BE service is acceptable only for
traditional Internet applications like e-mail, web browsing and file transfer. However, it is not adequate for the
applications like video conferencing, voice over IP (VoIP) and video on demand (VoD), which require high
bandwidth, low delay and delay variation. Obviously, with the emergence of new real-time applications and
Quality of Service (QoS) requirements, the Best Effort service becomes insufficient. Therefore, the Internet
community has developed a number of new technologies to provide QoS in the Internet such as IntServ,
DiffServ and MPLS. The differentiated service (DiffServ) is the most important distinct technology due to its
simplicity and scalability benefits. It has been endorsed by Internet Engineering Task Force (IETF) to satisfy
the requirements of new real-time applications. Internet Protocol was not designed taking into account mobility
of users and terminals. In few years later, the IETF has developed protocols such as Mobile IPv4 (MIP) and
Mobile IPv6 (MIPv6) for supporting seamless connectivity to mobile hosts. Mobile IPv6 is considered one of
the important host mobility protocols, which was defined more in (RFC 3775 and RFC 6275). This paper
acquaints with analytical analysis for the previously proposed scheme (DiffServ-MIPv6) that applies the
DiffServ methodology techniques to Mobile IPv6 network in order to suit the needs of both QoS guaranteed
and mobility in communication. The analytical study is investigated to evaluate the performance of the
proposed scheme (DiffServ-MIPv6) compared to the native standard MIPv6 protocol in terms of signaling cost.
The numerical results are measured against two factors, binding lifetime period and wireless link delay as well.
