Abstract
This document describes tools useful in relaying a data stream from a data device to a network tunnel, such as by enabling virtual switching using a provisional identifier to conceal a user identifier. These tools, for example, may use an inexpensive switch module to create virtual switch instances. To do so, the tools may assign data packets to a virtual switch instance by mapping the data packets to a particular provisional identifier and then modifying the data packets to include the provisional identifier. The switch module may then forward the data packets based on the provisional identifier rather than on the user identifier. The tools may remove the provisional identifier before forwarding the data packets to a destination.
