| Abstract: | In this paper, we pursue a performance analysis under hotspot traffic conditions of a four-level prioritized non-blocking baseband switch for use on board a switching multibeam satellite. Both finite input and output buffering as well as speed-up are employed to reduce the loss which is critical in a satellite application. In addition, in order to improve the performance of the two lowest priority users a head of line resolution (HLR) technique is implemented. It is shown that with HLR and the proper adjustment of the switch speed-up and the input and output buffers the loss can be substantially reduced. It is also shown that the dependence on the switch size which is characteristic of the unbuffered discard case is substantially reduced, even in a prioritized environment, allowing larger switches to be implemented. |
