ATM Reference Traffic System
Project Award Date: 0000-00-00
Current ATM network technology is emerging amid a storm of enthusiasm, conflicting claims about performance, and confusion about its suitability for a wide range of leading edge high performance computing and networking applications. There is, however, little disagreement in both the industrial and research communities that ATM is a promising technology deserving serious investigation. There is less agreement about precisely how the technology produced by the growing set of vendors should be evaluated. A problem currently facing Sprint, and the industry as a whole, is how to objectively evaluate and verify performance and interoperability of ATM system components. We are building the ATM Reference Traffic System (ARTS), which will address objective evaluation and verification of network performance and interoperability in several ways. First, ARTS will provide an inexpensive, standardized and reproducible traffic source. A reproducible traffic source will be a valuable aid in a wide range of network performance testing and customer service verification and demonstration situations. The system will use a modified version of the Linux system to produce the ATM traffic according to a specified profile or explicit schedule. The system modifications will all focus on increasing the accuracy with which the system can reproduce specific behavior. The system will also function as a traffic recorder, enabling the user to record ATM traffic events and store them for later analysis or reproduction. Finally, building the system will require incorporating host-to-switch signaling software that will enable us to evaluate how current standards support interoperability and will establish a platform within which to experiment with extensions to current standards necessary to correct any interoperability problems encountered.
