Abstract

As Internet traffic grows, current core network technologies will raise issues in terms of energy consumption. Here, the authors propose three possible optical network architectures for the next-generation Internet core, including an all-optical hybrid optical switching (HOS) network, an optical/electronic HOS network, and an all-electronic switching network. They evaluate and compare all three networks with regard to performance and power consumption via an event-driven simulator.
