In the MPLS-based mobile IPv6 network, when mobile node performs handover, it needs to rebuild label switching path, which impacts the handover delay and causes packets loss. Reused parts of the path overcome the above reasons, which propose a cross-router (CR) algorithm. It modifies the label information base (LIB), that is, increases two fields: the mobile node address and the time counter. When...
This paper presents a novel MPLS-based micro-mobility scheme by integrating MPLS and hierarchical mobile IPv6 (HMIPv6). It exploits the scalable QoS support capability of DiffServ-aware MPLS traffic engineering. Aggregated traffic of mobile users is forwarded through traffic engineered LSPs established along links with available resources. Moreover, traffic flows of different priority receive differentiated...
The Internet backbone has been enjoying the great many advantages of multi-protocol label switching (MPLS) for quite sometimes, as well as in wireless applications. The employment of MPLS in mobile services and applications was not noticeable until the beginning of the year 2000. However researches began extensive efforts to extend the MPLS capability to the wireless access networks. This is particularly...
This paper we discuss the architecture of a QoS based mobile ad-hoc network MANET using RSVP over multiprotocol label switch (MPLS). Classical IP routing provides only a "best effort" service, which makes routing simple, however no quality of service (QoS) will be provided to applications such as streaming voice and video. For the purpose of scalability, where many connections are to be...
