Summary:
This technical report discusses the challenge of defining the location of different kind of hand-over mechanisms (mobility) and Quality of Experience (QoE) concepts in the reference strata model of IPsphere. This reference model goes along with the current overlay architectures in standardisation (NGN, NGMN, IMS) as well as in the research communities (Daidalos). Mobility and QoE are important mechanisms to provide satisfying services in a Mobile and Future Internet. Especially mobility has different variations such as inter- and intra technology hand-over or inter- and intra-domain hand-over, device and session mobility. Mechanisms such as Mobile IP, which is located between the network layer and the transport layer in the Internet Protocol stack, can not satisfy al these variations. On the other side, the provisioning of QoE (end-to-end QoS) over a multi-provider environment is still under discussion, e.g. in the IPsphere project. A possible solution besides the IPsphere Overlay is presented in this technical report.
