    • PROBLEM TO BE SOLVED: To provide the early initialization of transmission of data in a network interface that includes a dedicated transmit buffer in a system which includes logic for transferring frames of data composed by a host computer into the transmit buffer. SOLUTION: The amount of data of the frame which is downloaded by the host to the transmit buffer is monitored to make a threshold determination of an amount of data of the frame resident in the transmit data buffer (34). A network interface controller includes logic (36) for initiating transmission of the frame when the threshold determination indicates that a majority of the frame is resident in the transmit buffer, and prior to transfer of all of the data of the frame buffer (34) into the transmit buffer. The monitoring logic includes a storage device (43), which is programmable for storing a threshold value. Thus, the threshold value may be set by a host system to optimize performance.

    • 要解决的问题:提供在包括用于将由主计算机组成的数据帧传送到发送缓冲器的逻辑的系统中的专用发送缓冲器的网络接口中的数据传输的提前初始化。 监视由主机下载到发送缓冲器的帧的数据量,以对驻留在发送数据缓冲器(34)中的帧的数据量进行阈值确定。 网络接口控制器包括当阈值确定指示该帧的大多数驻留在发送缓冲器中时,以及在将帧缓冲器(34)的所有数据传送到 发送缓冲区。 监视逻辑包括可编程以存储阈值的存储装置(43)。 因此,阈值可以由主机系统设置以优化性能。 版权所有(C)2006,JPO&NCIPI
