Abstract

This paper proposes a new failure-resistant ATM transport method for real-time applications (FRAT-RA). This method can prevent not only cell loss but also cell delay variation (CDV) even when a network failure occurs. First, a general overview of the existing fault-resistant method is briefly described and its problems for real-time applications are discussed. Next, the proposed FRAT-RA method is described in detail. Finally, evaluation results on the CDV of FRAT-RA and its QoS improvement are presented. The results show that failure-resistant and high-quality transmission of real-time signals can be achieved with FRAT-RA
