    Abstract: 近年來,許多的網際網路服務供應商(Internet Service Providers)已正式宣佈提供1Gbps速度服務,且也有部分的網路應用程序要求高速的傳輸速率以供使用;然而截至目前為止,大部分的家庭終端使用者都是使用無線基地台(Access Point)做為擴充,但這些裝置通常都無法達到最高的傳輸數率,即便無線基地台已經支援1 Gigabit傳輸速度,究其原因大部份與裝置晶片限制或系統非最優化為主要的兩大因素,也因為這兩大因素限制了網路傳輸速度。
    方法一: Boost網路軟體加速器
    方法二: Boost網路軟體加速器with QoS (Separate/Label Separate)
    ;In recent years, many internet service providers announced they start to deliver end users for 1Gbps network plan, and some network applications have 1Gbps minimum request of data transfer rate. Currently, most end users have Wireless Access Point (AP) at home, but they usually cannot approach highest data rate even this AP already supports Gigabit data rate. The reason may be related chipset limitation or system not optimized, hence the network speed is limited.

    In this thesis, we will promote a solution, Boost software network accelerator, to deal with this problem. This method can process numerous packets quickly and efficiently. It is a software-based solution and implemented in Linux Kernel, therefore it is not limited by different chipsets, that will be easy to migrate to embedded system.

    The Boost software network accelerator has 2 types.
    1. Boost software network accelerator
    2. Boost software network accelerator with QoS function (Separate / Label Separate)

    In our experiments, we performed the accelerator tests for different situations. If you want to approach highest data rate, you could perform type 1. Possibly you could add some QoS rules according to your requirement for type 2, that will ensure getting high quality for particular applications. According to this method, we really have improved network performance and got good results rather than original data rate of test equipment.
