    • A method to synchronize and upload an offloaded network stack connection between a host network stack and processing device is presented. A state object for each layer in the stack is sent to the device that includes state variables that are classified as a constant, a cached variable handled by the host, or a delegated variable handled by the device. State that must be updated by the network stack and the processing device is cleanly divided. For example, statistics are tracked by the host, the device, or the host and the device. A statistic tracked by both the host and processing device is divided into non-overlapping portions and combined to produce the statistic. Once an upload is initiated, the device achieves a consistent state and hands delegated states to the stack. Each layer in the stack takes control of its delegated state and resources at the device are freed.
    • 提出了一种在主机网络堆栈和处理设备之间同步和上传卸载的网络堆栈连接的方法。 堆栈中的每个层的状态对象被发送到包含状态变量的设备,该状态变量被分类为常数,由主机处理的缓存变量,或由设备处理的委托变量。 必须由网络堆栈和处理设备更新的状态是干净的。 例如,主机,设备或主机和设备跟踪统计信息。 由主机和处理设备跟踪的统计量被划分为不重叠的部分并组合以产生统计。 一旦上传被启动,设备实现一致的状态,并将委托状态指派给堆栈。 堆栈中的每个层都控制其委托状态,并释放设备上的资源。
