Abstract

In Elastic Lambda Aggregation Network (EλAN), fault recovery using an Optical Line Terminal (OLT) in a different Central Office (CO) is applicable due to virtualization of OLT and active Optical Distribution Network (ODN). In addition, the Time Division Multiple Access (TDMA)-based OLT sharing method has been proposed to maintain minimum connectivity of the excessive number of Optical Network Units (ONU) from a single OLT. In this letter, we report the experiments of these two fault recovery methods implemented on the software-based EλAN prototype system. The required time from failure detection to connection recovery was evaluated in these experiments.
