From the developer: "Virtual Gateway is a fail-safe QoS software solution that will discover, classify, and shape your network's application traffic. Virtual Gateway will also provide both real-time and historical application traffic reports. Virtual Gateway requires one Windows XP or 2000 PC on which you install the product. It can also be integrated with any existing router or switch to create a more sophisticated QoS solution that will meet the needs of the most demanding network administrators. The Virtual Gateway 'Quick Start Users Guide' can be found on the Pancho Networks web site and in the product GUI under the 'Help' section."
