摘要： A system and method are presented that enhance the performance of single and multiple-processor servers by taking advantage of the half-duplex nature of many HTTP requests. Upon receipt of an HTTP Get resource request, a single send and disconnect IRP is generated. The semantics of the send and disconnect IRP completion recognizes the half-duplex nature of the transaction by indicating a graceful close of the TCP/IP connection. This send and disconnect IRP is also completed without a queuing stage (queuelessly) on the processor that serviced the client request. To further enhance performance, the server FIN message to the client is included in the last data frame transmitted to the server. The invention also contemplates transmission of a single HTTP get and disconnect request by a client to allow acknowledgementless disconnection of the TCP/IP connection once a requested resource has been sent.

摘要： Methods are provided that allow high-level protocol drivers to cancel transmission requests that have been sent to low-level protocol drivers. Transmission requests are assigned cancel identifiers. Because one original request may be divided into several packets for transmission, the same cancel identifier is given to every packet that derives from the original request. High-level protocol drivers can request cancellation of all pending requests whose cancel identifiers match the one indicated. Cancel identifiers generated by different high-level protocol drivers are mutually distinct so one protocol driver cannot inadvertently cancel requests made by another. The protocol driver may divide its requests into logical flows and assign the same cancel identifier to all requests within one flow. Then, the protocol driver may cancel all pending requests within one flow while allowing requests in other flows to proceed to transmission. An application can use these methods to cancel requests sent to high-level protocol drivers.

摘要： A new communications connection timer management framework for handling network communications protocol timers is disclosed. The timer management framework separates transmission control blocks (TCBs) having scheduled actions from the set of all TCBs maintained by a server. The TCBs having scheduled actions are referenced by a time-space partitioned data structure having time-slots corresponding to a current protocol timer “tick” value. The active TCBs are placed within particular ones of the time-space partitions based upon their expiration times. During each timer check sequence (e.g., once every 100 millisecond timer tick for TCP protocol timers), the timer management framework accesses a partition associated with a current timer value and checks the TCBs referenced within the current partition.

摘要： 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.

摘要： A method to offload a network stack connection is presented. A request, which includes a list of resource requirements from each software layer in the stack, to offload the network stack connection is sent through the stack to the peripheral device. The device allocates resources for the list and sends a handle to each of the software layers for communication with the device. The state for each layer is sent to the device that includes state variables that are classified as a constant, a cached variable handled by the CPU, or a delegated variable handled by the device.
