摘要： A system and method of operating a client network computer in a disconnected mode. A client computer system includes a client storage device, a processor, a network interface, a failover server and a software manager. The processor is configured to execute software instructions stored in the client storage device. The network interface is configured to connect the client computer system to a remote network server unit. A failover server implemented on the client computer system is configured to provide functionality similar to the remote network server unit by accessing a copy of a network database file stored on the client storage device. A software manager stored in the client storage device is configured to cause the client computer system to connect to the remote network server unit if the remote network server unit is available or to cause the client computer system to connect to the failover server if the remote network server unit is not available. The remote network server unit is configured to provide a client cache image file to the client computer system. The client cache image file contains information, such as a copy of the operating system, a copy of client boot configuration files and a copy of the network database file, which causes the client computer system environment to appear to a user as though the client computer system is connected to the remote network server unit when the client computer system is actually connected to the failover server.

摘要： One embodiment of the present invention provides a system that dynamically changes the TCP behavior of a network connection. First, the system receives a request to change the TCP behavior for a network connection that allows communication between a first computer system and a second computer system. In response, the system changes a function associated with the TCP behavior of the network connection to a new function that provides TCP behavior better-tuned to the needs and environment of the network connection.

摘要： One embodiment of the present invention provides a system that buffers data inside of a byte-stream protocol at a transport layer on a client, which is receiving the data from an external source. The system operates by receiving a configuration parameter at the transport layer from an application executing on the client, wherein the configuration parameter specifies a condition upon which data buffered at the transport layer is to be sent to the application. The system then buffers data destined for the application at the transport layer on the client, and sends the buffered data to the application when the condition specified by the configuration parameter is met. Buffering data at the transport layer on the client facilitates more efficient processing of system calls.

摘要： One embodiment of the present invention provides a plug-in architecture for a network stack in an operating system. The network stack includes a set of functions configured to modify a set of parameters that are likely to change based on the network environment. The architecture includes a plug-in framework within the network stack that allows the set of functions to be dynamically changed in order to change the TCP behavior of the network stack to suit the network environment.

摘要： One embodiment of the present invention provides a system for sending data to a remote host using a socket. During operation the system receives a request from an application to write data to the socket, wherein the data is stored in a source memory buffer in user memory. Next, the system initiates a DMA (Direct Memory Access) transfer to transfer the data from the source memory buffer to a target memory buffer in a TCP (Transmission Control Protocol) Offload Engine. The system then returns control to the application without waiting for the TCP Offload Engine to send the data to the remote host.
