Abstract
A system for and method of sending network problem information along a communication path of a network having an unknown configuration and inaccessible components including a first device for observing network problems and a second device for relieving network problems. Upon observation of a problem, the first device generates and sends an enhanced loopback test message to the source of the problem. The enhanced loopback test contains information regarding the source and the nature of the problem. The second device, being along the path of the loop between the first device and the source, receives the problem information and responds by reducing the problem as appropriate.
