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...
Providing a seamless handoff and quality of service (QoS) guarantees is one of the key issues in real-time services. Several IPv6 mobility management schemes have been proposed and can provide uninterrupted service. However, these schemes either have synchronization issues or introduce signaling overhead and high packet loss rate. This paper presents a scheme that reduces the handoff latency based...
Current mobile network architecture is constructed through introducing mobile IP protocol on the basis of IP network. On the one hand it cannot break away from the inherent limitation of IP network, such as no strong security, complex forwarding devices, lack of high expansibility and no QoS guarantee. On the other hand it brings some new problems due to the repair to IP network, such as the triangular...
