Design and performance evaluation of protected Super-EPON Access networks using a dedicated protection ring architecture

This paper describes and tests the feasibility of a protected super Ethernet passive optical network (Super-EPON). The architecture of the Super-EPON is based on a two-fiber ring that provides protection to the feeder section of the supported EPONs. The performance evaluation of the network is measured by simulating the behavior of dynamic bandwidth allocation (DBA) algorithms with quality of service (QoS) support in the upstream traffic management. The results are examined in terms of mean packet delay, mean bit rate per optical network unit (ONU), time-slot occupation efficiency, data packet loss, and overhead due to Ethernet headers and multi-point control protocol (MPCP) messages.
