A Simplified Cloud Computing Network Architecture Using Future Internet Technologies

Abstract

Cloud computing is expected to provide quick, agile, stable and reliable services. Traditional cloud computing network architecture is too complicated to fulfil these services. Future internet is proposed to reinvent the Internet using a clean slate approach. Many new technologies including OpenFlow, Autonomic Computing, Content-Centric Network, Cross-layer communication and Locator/ID Separation Protocol are proposed to improve the limitations of current Internet. The main contribution of this paper is to propose a simplified cloud computing network architecture. This architecture first adopt OpenFlow switch simulate Firewall, SLB, and Switch simultaneously. The network devices are consolidated into one single device. Then, using Autonomic Computing concept can reduce operation cost and simplify management effort. Finally, Locator/ID Separation Protocol technology is adopted to enhance network security. This novel cloud computing network architecture is implemented and experimented in our laboratory. This novel network architecture results in huge cost saving both CapEx and OpEx.
