本論文主要在提出以太網路TCP/IP頻寬管理系統核心之設計方法。在端點對傳的TCP/IP資料連線中，此系統設計定位為穿透式網路裝置並提供主動式的網路控制架構。所有穿過裝置的封包會暫存在系統佇列中，然後依照管理者所制訂頻寬管理之政策決定釋放的時間點，達到控制頻寬的目的。
目前常見的頻寬管理方法，如延遲回應（delayed-ACKs）和變更TCP滑動視窗（Sliding window），均需與TCP擁擠管理演算法緊密結合。使用本設計不需要改變TCP/IP協定，就可以精確地控制以太網路上TCP/IP連線速率，使其遵循網路頻寬政策或服務品質保證（Quality of Service, QoS）並且能和其他擁擠管理協定完全相容（如 Congestion Management Protocol和 ECN）。

論文中會敘述透過本系統演算法可以達成的服務品質保證的種類，並能達到相當不錯的系統效能。在我們製造近乎真實的TCP/IP連線環境下，展現頻寬管理的高精確度。

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.
