 <\/p>\n

En redes tradicionales no hay visibilidad terminal a terminal (end-to-end)\u00a0 de las rutas de red y las aplicaciones no siempre se enrutan optimamente. KEMP SDN Adaptive se hace cargo de esta perdida de visibilidad al acceder a informaci\u00f3n de los patrones cr\u00edticos de flujos de datos en la red, directamente desde el controlador SDN. Con esto en mente, las aplicaciones pueden ser dirigidas dinamicamente al servidor \u00f3ptimo a trav\u00e9s de la elecci\u00f3n de la mejor v\u00eda disponible en la infraestructura de conmutaci\u00f3n de la propia red.<\/p>\n

Topolog\u00eda de Soluci\u00f3n<\/h2>\n

En el ejemplo de abajo, las granjas de servidores #1 y #2 est\u00e1n conectadas a switches habilitados con OpenFlow lso que son monitoreados por el controlador SDN de esa red. El KEMP SDN Adaptive LoadMaster interroga el controlador SDN para obtener el rendimiento de los switchs y la informaci\u00f3n de estados. Al\u00a0 evaluar <\/span>el<\/span> <\/span>funcionamiento<\/span> <\/span>del<\/span> switch <\/span>de <\/span>ruta<\/span> <\/span>#1<\/span> se encuentra que <\/span>impacta<\/span> <\/span>en<\/span> el <\/span>rendimiento y por tanto se equilibrar\u00e1n las cargas hacia <\/span>la ruta de <\/span>acceso<\/span> <\/span>#2<\/span> y as\u00ed\u00a0<\/span><\/span>reducir<\/span> <\/span>el<\/span> <\/span>impacto<\/span> <\/span>de<\/span> <\/span>la<\/span> <\/span>condici\u00f3n<\/span> de saturaci\u00f3n del switch de la ruta #1.<\/span><\/span><\/p>\n

\"KempSDN\"[:en]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.<\/p>\n

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.<\/p>\n

Solution Topology<\/h2>\n

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.<\/p>\n
