Abstract

A system for automatic program generation which receives a number of input format descriptors and a number of output format descriptors. The system generates a program for converting an input data sequence having a format described by input format descriptors to an output data sequence having a format described by the output format descriptors. The program may then be executed responsive to an input data stream, wherein a portion of the input data stream corresponds to the input data sequence. The input data sequence and output data sequence consist of a number of data type indicators. In an exemplary embodiment, the input data type indicators correspond to fields of data units received by a forwarding device, and the output data type indicators correspond to fields of corresponding data units forwarded by the forwarding device. In the exemplary embodiment, the generated program is executed on a hardware processor to convert a data unit received on a communication link over a information flow to an output data unit for transmission on a second communication link. The initial data unit of the information flow triggers generation and loading of the program while the forwarding device is up and running.
