Towards Minimizing Service Degradation during MIPv6 Handovers

Abstract

Since the correspondent registration messages in MIPv6 go through all the nodes that are responsible for QoS configuration after handover, we propose to extend the Binding Update (BU) messages of standard MIPV6 to carry schemedependent QoS data. Correspondent registration is performed by these new Agent Update (AU) messages. The AU messages are intercepted by QoS Agents, which are located in the "critical" nodes that are responsible for QoS configuration. Thus by the time that the correspondent registration is complete, the QoS configuration has also been updated along the data path, which minimizes the service degradation due to handover. This approach also provides a unified solution for heterogeneous QoS schemes that may be applied along the data path.

Performance evaluation of qos-agent assisted mipv6 handoff scheme

“…We have previously proposed [2] a new approach that supports heterogeneous QoS models and is able to reduce the QoS configuration latency after MIPv6 handoff. Our approach does not require extensions to existing QoS schemes.…”

“…To copy otherwise, to republish, to post on servers or to redistribute to lists, requires prior specific permission and/or a fee. This paper presents performance evaluation of a QoS Agentassisted MIPv6 handoff scheme that we previously proposed in [2]. We compare our scheme with other schemes that aim to interwork MIPv6 and different QoS provisioning methods.…”
