Visualization of ATM virtual path connection networks

ATM supports multiple quality of service classes for different application requirements. A Quality of Service is associated with a virtual path connection. Dynamic reconfiguration can generate an optimal virtual path connection network and maintains sufficient capacity to carry the established calls in progress. We developed a tool to present information specific to the changes of virtual path network. We visualize network traffic characteristics including dynamic routing, variable link utilization, capacity distribution and objects information. This visualization provided new insight changes of reconfigurable virtual path connection networks. Our tool is intended to help administrators and researchers understand networks as well as identifying anomalies and bottlenecks within these networks.
