Abstract
An experimental study of the Resilient Packet Ring (RPR) media access control
(MAC) technology that is optimized for IP traffic in the metropolitan-area-network
(MAN) environment is described. The study involved the deployment and trials of a
RPR testbed encompassing a public optical fiber infrastructure in which Cisco
Systems’ Dynamic Packet Transport (DPT) Ring Technology—a prestandard RPR
implementation—was used. We focus on a number of important RPR protocol features
that are vital to the future success of RPR as a MAN/wide-area-network (WAN) network
technology. Related research on RPR/DPT has been done so far through simulation
studies only. Standardization of RPR is currently being performed by the Institute
of Electrical and Electronics Engineers (IEEE) 802.17 working group and is expected
to be completed in 2003. Also, we present and discuss the experiments and tests
performed to investigate the key features of RPR, along with the results
obtained.
