A unified metascheduler architecture for telecom grade cloud computing

In cloud computing, Some Cloud Service Providers (CSPs) have their own cloud infrastructure which is centralized or geographically distributed, small or large-scale. Others act as Brokers (CSBs) who integrate and launch services based on multiple CSPs' infrastructures. How to meet the complex requirements for different scenarios while provide high quality, especially telecom grade cloud services in terms of most appropriate resource utilization, high service level assurance, operation, administration, maintenance, and security, even interoperability amongst different clouds is becoming more and more concerned. In this paper, a unified MetaScheduler architecture is proposed to address the aforementioned challenges. The functions of the components are defined and workflows for different networking scenarios are described. The detailed analysis shows that the architecture can support different scenario cloud system implementation and realize telecom grade services.
