Expanded implementation of output buffer mechanism in the Internet router

With the rapid increase of the traffic demand in the Internet, it is necessary to provide a priority control mechanism in the Internet router in order to realize suitable transmission for various attributes of multimedia traffic. Therefore we have proposed the output buffer control mechanism by flow management, and hardware implementation is performed as a basic design. This implementation has only the basic functions. In this paper, we expand our implementation to realize the advanced QoS guarantee. Concretely, we propose and implement the two ideas, "correspondence to variable length packets," and "correspondence to multiple ports".
