Embodiments of the present invention provide a database system that is optimized by using hardware acceleration. The network device strips the stream-specific routing information from the plurality of obtained data packets to produce a plurality of stream-specific payload portions, which are merged into a shared payload portion of a stream-multiplexed data packet that includes common routing information for the plurality of streams in a common header portion. The indicator means may be further responsive to the timer to indicate when a second predetermined time has elapsed. The device offers an improvement over prior art of being capable of adjusting the position of the stimulating electrodes.
