ABSTRACT:
An application programming interface for translation of transport-layer sessions is presented. The system includes kernel-mode support for application-controlled network address translation and user-mode implementation of the redirect API routines. An application process may request that a network gateway modify the source and/or destination of a given network session in a manner transparent to the original source host and/or the replacement destination host. With the generalized NAT (gNAT) of the instant invention and its associated API, both the source and the destination addresses of message packets may be changed. The address changes are mapped in the gNAT, and may result in apparent sessions between different clients and servers. Depending on the protocol in use (e.g. TCP or UDP), the address translation may be made dynamically by the gNAT, under the command of the application, and take place at the kernel level.
