Abstract

In this paper, we propose, design, and demonstrate a novel Intra-PON Flow transmission with optical reroute using a Quasi-PAssive Reconfigurable (QPAR) node. The network can be reconfigured adaptively according to the monitored traffic status in a software-defined manner. Simulations show that PON with reroute architecture can achieve ∼20% higher network capacity comparing to PON without reroute case with the same traffic waiting time or blocking probability requirement. PON with reroute consistently outperforms PON without reroute configuration with 20% larger throughput and 24% less power consumption with the Intra-PON traffic ratio of 0.3. In addition, adaptive Intra-wavelength assignment with a QPAR node can adapt to the subscription rate growth with time, and provide cost and power savings compared to PON without reroute and fixed PON with reroute architectures by approximately 20% and 10%. Moreover, adaptive Intra-PON architecture with a QPAR node can facilitate efficient multicast transmission for video or file backup among multiple serves located in different access networks, which can provide lower traffic waiting time, 14% power saving, and support roughly 30% higher traffic comparing to the fixed PON with reroute design with a multicast ratio of 0.5.
