Systems and methods presented herein provide for resetting a controller in a Single Root InputOutput Virtualization architecture. The cut-through forwarding module comprises at least one receiver component arranged to receive data to be forwarded, and to generate a request for transmission of a block of data upon receipt thereof, and at least one controller unit arranged to execute at least one thread for processing requests generated by the at least one receiver component. The protocol also provides for accurately detecting the transition from one time slot to another, in a given data transaction. In another embodiment, the produced KGS ester is reacted in one or several additional steps so as to obtain L-ascorbic acid.
