A Design of Optical Networks in Cloud Computing Services

Abstract

Modern optical networks elastic features have been adopted quickly by the web-scale providers such as Microsoft, to keep pace with tremendous bandwidth growth. In particular, transceivers of bandwidth-variable, colorless flexible-grid reconfigurable optical add–drop multiplexers, and a variety types of service are supported to improve network efficiency for cloud network operators, the ability to choose a variety types of optical source are integral. In this analysis, for cloud services, optical networks architecture is based on novel Stateful PCE-Cloud (SPC). For improving the maximum utilization of resource and reliability to the construction of SPC, the cloud computing technologies (e.g. parallel computing and virtualization) are applied. Detailed description and design are provided to the SPC components. Relationships of different potential cooperation between Region Stateful PCE Cloud (RSPC) and Public Stateful PCE Cloud (PSPC) are investigated. Moreover, constraint-based routing scheme base on RSPC and PSPC cooperation and policy enable are presented. A design of Optical Network in Cloud Computing Services (ON-CCS) shows increases in elasticity as client number increases, storage capacity and computing capability will also increase.
