Optical Networks for Grid and Cloud Computing Applications

摘要: The evolution toward grid and cloud computing as observed for over a decennium illustrates the crucial role played by (optical) networks in supporting today's applications. In this paper, we start from an overview of challenging applications both academic (further referred to scientific), enterprise (business) nonprofessional user (consumer) domains. They pose novel challenges, calling efficient interworking IT resources, processing storage, well network that interconnects them provides access their users. We outline those applications' requirements, including sheer performance attributes (which will determine quality perceived end users applications), ability adapt changing demands (usually elasticity) possible failures (i.e., resilience). outlining foundational concepts provide building blocks grid/cloud solutions meet stringent application requirements highlight, prominent is optical networking. pieces solution studied respect span transport layer mechanisms located higher layers (e.g., anycast routing, virtualization) through appropriate control plane extensions middleware). Based on study, conclude identifying challenges research opportunities can enable future-proof systems pushing virtualization paradigms networks).
