On the Energy-Efficiency of a Packet-Level FEC Based Bufferless Core Optical Network

The authors proposed packet-level Forward Error Correction (FEC) as a promising technique for enabling buffer-less core optical networks. In this paper, they systematically analyze its energy-efficiency and show that it can produce substantial power savings. Improving the energy-efficiency of core routers has attracted widespread attention over the past few years. While various approaches have been proposed to tackle this problem, their focus is on router packet buffers, which are of the order of a few Gigabytes, and accounts for nearly 10% of the power consumed by a line-card.
