Two-Phase Load Balancing for Data Center Networks using OpenFlow

This invited paper describes an OpenFlow solution for two-phase load balancing optimized for data center networks. The solution uses aggregate flows and Proxy ARP procedure in order to achieve reduced size of OpenFlow tables, fast flow configuration and compatibility with standard Ethernet networks. The paper presents modification of the proposed solution, based on configuration of interconnected groups of aggregate flows. The paper also discusses the scalability of the solution
