1. MobileIP QoS Requirements

Re : RFC 3583

Performance RequirementsMinimize the interruption in QoS at the time of handover

Localize the QoS (re)establishment to the affected parts of the packet in the network

Releasing after handover the QoS state (if any) along the old packet path

Interoperability requirementsInteroperability with mobility protocols

Interoperability with heterogeneous packet paths as regards QoS paradigms

Misc requirementsQoS support along multiple packet paths

Interaction with wireless link-layer support for QoS



Minimize the interruption in QoS at the time of handover Performance Requirements

Number of packets treated by default QoS at intermediate node should be minimized
