In session-based routing, entire sessions are routed and not individual data packets as in classic routing. Session routing uses communication protocols that temporarily support the exchange of information.
Session-based routers keep the route open until the session is completed. They can interpret requests to the application and use the application-specific policies and determined the route through the network through them. The network becomes a service-oriented structure because of the routing points set in real time.
Session-based routing makes the network architecture more dynamic, increases network security and reliability, and achieves higher data throughput through dynamic route determination. Session-based routing is ideal for SD-WANs, hybrid clouds, Internet of Things (ioT), and remote operations.
