A method and system for directing data transfers between applications and devices residing on different computers or devices using an adaptive flow control protocol has been described. When an application or device requests to transfer data with another application or device, the adaptive flow control protocol adapts the way data is transferred by observing when an application that is receiving data posts a receive buffer and detects the receive buffer’s size. Based upon the application’s or dev…

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 sta…

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. …

A service is disclosed that discovers information about the logical networks to which a computer is connected and provides that information to applications. The information is keyed to names constructed by the service. There is a mapping between the names and the logical networks. Applications may rely on the names when selecting a configuration to use with a given logical network. The network name may be correlated with other information, such as physical network interface(s) on the computer th…

A method, computer readable medium having computer executable instructions, and a computer readable medium having stored thereon a data structure for signing and validating Session Initiation Protocol (“SIP”) routing headers are disclosed. A SIP node may receive a SIP request including a message header. A signature based upon at least a portion of the message header and a SIP node header entry may be generated. The signature may then be inserted into the SIP node header entry.
