摘要

自1983 年美國國防部要求所有要連接ARPANET 的電腦設備都要使用TCP/IP 通 訊協定以來，TCP/IP 協定廣泛地使用在網際網路上。它提供一個穩定的傳輸環境給 應用軟體。TCP/IP 協定通常包含在作業系統內，由於些協定需要大量的運算也因此 佔用了許多的系統資源。自過去以來，有許多的研究都在探討如何將網路傳輸做最 佳化，其中有許多探討TCP/IP 及其相關的效能測試的研究。此研究主要是探討將 TCP/IP 協定卸載到一個特定的子卡上，並由卡上的微處理器處理相關的協定以減輕 系統的負擔。此論文完整地描述並以實例說明製作、設計的步驟並提出具體的效能 測試報告。

Since American Ministry of National Defense required all to use the TCP/IP
communication protocol while connecting computer equipments of ARPANET in 1983,
TCP/IP protocol is widely used in the internet network. It offers a steady transmission
environment for the software application. TCP/IP protocol usually is included in the
operating system, because some protocols need a large amount of operations that occupy
many system resources. A lot of previous research is discussing how to optimize the
transmission the network, which included the TCP/IP and relevant efficiency test. This
research is mainly to probe into and offload TCP/IP protocol calculation onto a specific
adapter, in order to lighten the systematic burden by the I/O processor of the adapter.
This thesis describes completely, states the step designs, and provides an
efficiency/performance test result with the some instances.
