ISD: Network Selection for Cloud Services Date:2012-05-15 Authors: Juho Pirskanen, Renesas Mobile Corporation
Abstract We consider network selection for a cloud service use case. Juho Pirskanen, Renesas Mobile Corporation
Motivation • Significant number of services are not local but belong in a Cloud, globally located • Email, video download, music streaming etc. are examples of today • It could be envisioned that due to improved, always on, broadband cellular connectivity and combination of IEEE802.11 technology the number of services will further increase • Introduction of completely new ones can be foreseen – predicting details of those is quite impossible • Typically there is a number of different networks available • Each can provide connectivity to the network • Price per bit will continue to go down • Users are more interested in fluent and seamless connectivity and usability of applications - no manual connectivity setup • Users don’t know which applications require connectivity to the cloud and when Juho Pirskanen, Renesas Mobile Corporation
Use Case • User of electronic consumer device starts to use application XYZ in his device • The application-XYZ requires connectivity to cloud services • Device has not yet associated to any network as it has not been used for while • Multiple different networks available at that location • Some networks are not accessible to the user • Multiple networks available which could be used for the connection to the cloud • Each network may differ, as for example, in terms of: • Supported authentication mode, e.g. WEB based or USIM based • Supported security • Available latency and throughput • Network load or coverage/mobility support • Network Operator preferences • In the best case: • The device is able to make a “clever” network selection, at once, so that application can operate seamlessly with high QoE without any manual intervention of the user • In the non successful case (which we should avoid): • User realizes that application does not work properly and takes manual action to select network and provide authentication credentials Juho Pirskanen, Renesas Mobile Corporation
Connection to cloud is most of the time the service that user desires • User prefers connectivity without manual intervention • Devices needs to make “clever” decisions • ISD work could provide additional information and new means for this “clever” decision making process • Some of this work has been potentially done in 802.11u and WiFi-alliance already • Review of prior work is needed • To get holistic views in ISD study group it is proposed to include this use case in the use case document for future considerations Conclusions Juho Pirskanen, Renesas Mobile Corporation
Do you agree that the use case presented in slide 4 should be included in use case document? Straw poll Juho Pirskanen, Renesas Mobile Corporation
