Title: Load balancing and admission scheduling in pull-based parallel video servers
Inventor: LEE YIU BUN
IPC: H04L12/56
Filed: 2008-09-19
Abstract: A pull-based parallel video server system and method of implementation useful in an on-demand video system includes a plurality of slave admission schedulers operating in parallel with a master admission scheduler to back up the master admission scheduler that controls access to an array of pull-based video servers according to a protocol that accounts for jitter and loss of packets, as well as network delays. A transport protocol is provided that improves video data throughput under such conditions. To determine the architecture and functional requirements of the redundant admission schedulers, an analytical tool in the form of a performance model has been developed that incorporates network delays, delay jitters and packet losses on the communication links between the clients, schedulers and servers.

Title: Communication method
Inventor: NIWANO KAZUHITO
IPC: H04W28/16
Filed: 2005-09-22
Abstract: There is a problem that no unique specific detailed regulation is existent with respect to mobile station status information to be notified by mobile stations to a fixed station, so that the operations of the mobile stations within a communication system may be different from one another and hence no efficient scheduling (wireless resource assignment) of the uplink can be achieved. A communication method includes a transmission process in which to multiplex a transport channel, on which data is transferred from an upper order layer, with a physical data channel and transmit the multiplexed channel to a fixed station; a status notification process in which to notify status information including information related to a transmission power margin to be used for a scheduling; and a transmission control process in which to receive a result of the scheduling to control the transmission process. In the status information notification process, indexes added to respective predetermined transmission power margin levels as divided between the upper and lower limits of the transmission power margin are notified of as the status information.
