Abstract

Data Center Networking (DCNs) is a fast emerging enterprise application that is driving metropolitan bandwidth needs. This paper evaluates the needs of this emerging IT-centric, bandwidth voluminous and service rendering application from a metro optical networking perspective. We identify a set of needs called CAVALIER (Consolidation, Automation, Virtualization, Adaptability, Latency, Integration, Economy and Reliability) that are underlying requirements for a network to support DCN services. The CAVALIER requirements are met by proposing a metro optical solution which is based on light-trail ROADM technology. Light-trails exhibit properties such as dynamic bandwidth provisioning, optical multicasting, sub-wavelength granular support and low-cost for deployment. Adapting lighttrails to DCN needs is discussed in this paper through engineering requirements and network-wide design. Each aspect of the CAVALIER requirement is then mapped on to light-trail technology. Simulation results are shown to lead to performance betterments
