A Framework for End-to-End QoS Context Transfer in Mobile IPv6

Providing Quality-of-Service (QoS) guarantees and mobility support for Internet devices has become a hot research topic in the Next Generation Internet research, since mobile computing is getting widespread. Context transfers allow better node mobility support, and avoid re-initiation of signaling to and from a Mobile Node (MN). However, Context Transfer Protocol (CTP) [1] proposed by IETF can not meet the need of end-to-end QoS mechanisms because contexts are only transferred between Access Routers (ARs). This paper presents a framework for end-to-end QoS context transfer based on the architecture of F-HMIPv6, which may provide an end-to-end QoS context transfer for real-time applications, therefore they can get promptly the same forwarding process, minimize the handover service disruption, and avoid initiating the endto-end QoS signaling from scratch after an MN performs handovers. The Context Transfer Data message containing the QoS context information, a hop-byhop extension IPv6 op...
