AbstractIntroductionOptical Data Center Networks2.1 Optical Switching Technologies2.3 Optical Data Center Network: State-of-art2.4 Technical ChallengesConclusionTo date, three main optical switching technologies have been investigated which resulted in increasing data transfer capabilities for the data center networks. Optical Circuit Switching (OCS): OCS has three distinct steps: links set-up, data transmission and links tear-down. One of the main features of OCS is its two-way reservation process in theSee more on arxiv lasercomponents
