Cloud computing is expected to provide quick, agile, stable and reliable services. Existing Cloud computing network architecture is very complexity. In order to improve security, management and energy saving in cloud computing network, this article proposes a simplified cloud computing network architecture based on OpenFlow, Autonomic and Identifier Locator split technologies. This new network architecture design is more cost effective, on-demand provision, and secure than existing cloud network architecture. This novel cloud computing network architecture had been implemented and experimented.

Cloud computing is expected to provide quick, agile, stable and reliable services. Trad itional cloud co mputing 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 Co mputing, Content-Centric Net work, Cross-layer co mmunicat ion and Locator/ID Separation Protocol are proposed to improve the limitations of current Internet. The main contribution of this paper is to p ropose a simp lified cloud co mputing network architecture. Th is architecture first adopt OpenFlow switch simu late Firewall, SLB, and Switch simultaneously. The network devices are consolidated into one single device. Then, using Autonomic Co mputing concept can reduce operation cost and simplify management effort. Finally, Locator/ID Separation Protocol technology is adopted to enhance network security. This novel cloud co mputing network architecture is implemented and experimented in our laboratory. This novel network architecture results in huge cost saving both CapEx and Op Ex.
