| Summary: | 碩士 === 國立清華大學 === 資訊工程學系 === 89 === The thesis proposes a kernel design of bandwidth control system for TCP/IP over Ethernet. This system acts as a transparent device in the end-to-end uni-cast flow path and provides active network control architecture. The received packets will be queued inside first and then according to the bandwidth management policy, made by the MIS manager, these packets will be forwarded in a suitable time to achieve the allocated bandwidth.
The proposed scheme precisely controls the rate of TCP/IP flows over Ethernet without modifying the TCP/IP protocol. The famous rate control schemes, such as delayed-ACKs scheme or changing window-size scheme, are tightly bounded with the ways of TCP congestion avoidance. Nevertheless, the proposed scheme is independent with TCP congestion managements. This novel feature makes the proposed scheme be completely compatible with any congestion avoidance protocols, such as CM or ECN.
