Abstract
This document describes tools useful in relaying a data stream from a data device to a network tunnel. These tools may utilize an encapsulation scheme to convert data packets from a user format to a tunnel format required by a network tunnel. Similarly, the tools may utilize a de-encapsulation scheme to convert data packets from the tunnel format to the user format required by the user. The tools may also forward the data packets from a user network to the network tunnel and vice versa, through a conventional switch module. In some embodiments, the tools do so by modifying the data packets to add a provisional identifier recognized by the switch module to map a particular data stream into a particular network tunnel.
