Managing multi-tenant services for software defined cloud data center networks

As cloud computing data centers grow larger and networking devices proliferate, many complex issues arise in the network management architecture. We propose a framework for service offerings in a dynamic cloud network, based on software defined networking principles. The proposed approach also facilitates the use of multi-tenancy applications by providing redundant, vendor agnostic zone controllers with a hierarchical network manager. This approach enhances network security and supports converged Fibre Channel over Ethernet storage. Experimental implementation is demonstrated in a multi-tenant cloud test bed using a hybrid environment including both KVM and VMWare components.
