A speed-increasing machine for water includes a frame member, a plurality of buoyant members mounted to the lower end of the frame member, a motor mounted to the center of the frame member, and a shielding cover mounted outside the motor. The engine 10 comprises a supercharger 11 and an exhaust gas recirculation device 12. The inner tube of each extension beam is connected to the outer wall of the extendable room using a pivot connector that includes a mounting plate which has extending from it spaced apart support plates that provide bearing surfaces to support a journal. Router dispatch modules connect the high speed switch to a node attached to a high speed link for forwarding each data frame toward a dynamically selected target low speed module via the high speed switch, such that the dynamic selection of the target low speed module is based on detection of the module with the least load.
