KEMP SDN Adaptive dynamically enriches Layer 4 and Layer 7 load balancing policies with Layer 2 information extracted from an SDN Controller. By using extracted metrics such as network congestion, SDN Adaptive makes more intelligent forwarding decisions enhancing the application delivery QoE and service levels.

In traditional networks there is no end-to-end visibility of network paths, and applications are not always routed optimally. KEMP SDN Adaptive addresses this lack of visibility by accessing critical flow pattern information from the SDN Controller. With this approach applications can be routed dynamically to the optimal server via the best path available on the switching infrastructure.

Solution Topology

In the example below, the server farms #1 and #2 are connect to OpenFlow enabled switches which are monitored by the SDN controller. The KEMP SDN Adaptive LoadMaster polls the SDN controller for switch performance and state information. Should the performance of switch path #1 be evaluated as impacting on performance, traffic will be balanced in more to switch path #2 to reduce the impact of the switch condition.
