Traditional TV provides only a very passive experience. Recent trends suggest that users would be interested in taking a more active role while watching TV. This demo paper presents the Interactive television (iTV) platform, which offers a solution in giving the TV-audience a chance of active participation. The iTV platform enriches TV with additional content and interactivity, making it more attractive for the audience. In order to support multi-user and personalized access to the iTV services mobile devices are used. To provide an easy way to offer and use services an ad-hoc service architecture - the Universal Plug and Play (UPnP) architecture - has been used.
Fast Send Protocol - Minimizing Sending Time in High-Speed Bulk Data Transfers.Koch, Christoph; Rabl, Tilmann; Hölbling, Günther; Kosch, Harald (2007). 173-179.
Over the last decades the Internet traffic has grown dramatically. Besides the number of transfers also the data sizes have risen. Traditional transfer protocols do not adapt to this evolution. Large-scale computational applications running on expensive parallel computers produce large amounts of data which often have to be transferred to weaker machines at the clients’ premises. As parallel computers are frequently charged by the minute, it is indispensable to minimize the transfer time after computation succeeded to keep down costs. Consequently, the economic focus lies on minimizing the time to move away all data from the parallel computer whereas the actual time to arrival remains less (but still) important. This paper describes the design and implementation of a new transfer protocol, the Fast Send Protocol (FSP), which uses striping to intermediate nodes in order to minimize sending time and to utilize the sender’s resources to a high extent.
