Carrier-grade distributed open cloud computing for telecom operators

Abstract

In this paper a carrier grade distributed open cloud computing architecture is designed for telecom operators. Different from public cloud service providers, telecom operators combine their network capabilities and cloud infrastructure services together to provide inexpensive but high quality cloud services, with their deep understanding of and strong relationship with individual consumers and enterprise customers. Requirements and challenges, including performance, scalability, SLA management, security, network optimization, and unified management are discussed, and key technologies are figured out accordingly. Cost effective hardware and software configuration, distributed infrastructure deployment model as well as operation process are proposed, and end user experience of cloud based applications such as online game, high definition video will benefit from low latency and high bandwidth of back bone and service delivery network owned by operators.
