A load-balancing apparatus is implemented as an application over the SDN controller. Such an application is executed to configure and reconfigure the switches to achieve near-optimal load balancing, even when the traffic load changes. For each cluster, a near-optimal explicit routing configuration is determined. The combination of explicit routing (cluster-specific) and destination-based routing (same for all clusters) is used to achieve near-optimal load balancing for each cluster."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Apparatus and method for dynamic hybrid routing in SDN networks to avoid congestion and balance loads under changing traffic load","description":"Given a large number of traffic matrices, the matrices are divided into M clusters, where M is a relatively small number.
