ATM Troubleshooting
Overview This paper presents basic ATM testing techniques. It also details how testing ATM networks poses challenges not encountered in other WAN or LAN environments, such as Quality of Service (QoS) applications and techniques that target the specific measurement parameters, policing that simulates the behavior of ATM edge switches, and signaling that emulates the behavior of switched virtual circuit (SVC) set up. Asynchronous Transfer Modes strength lies is in its ability to handle virtually any kind of digital traffic (voice, video/images, data) in both a LAN or WAN environment. In addition, ATM provides permanent virtual circuit (PVC) and switched virtual circuit (SVC) capabilities and Quality of Service (QoS) guaranties. But because of these advantages, troubleshooting ATM networks involves unique challenges. While the traditional ‚test the layers of the stack approach can be used, ATM also requires specific test applications in order to adequately examine all aspects of its operation. These include basic network traffic decoding and statistical analysis, SVC signaling tests, LAN Emulation tests, and QoS tests to evaluate cell loss / cell delay and policing functions.
