Hybrid Optical and Electrical Network Flows Scheduling in Cloud Data Centers
Hybrid intra-data centre networks, with optical and electrical capabilities, are attracting research interest in recent years. This is attributed to the emergence of new bandwidth greedy applications and novel computing paradigms. A key decision to make in networks of this type is the selection and placement of suitable flows for switching in circuit network. Here, the authors propose an efficient strategy for flow selection and placement suitable for hybrid Intra-cloud data centre networks. They further present techniques for investigating bottlenecks in a packet networks and for the selection of flows to switch in circuit network. The bottleneck technique is verified on a Software Defined Network (SDN) testbed.
