Benefits of AppNav-XE

Benefits of AppNav-XE

• Enables enterprises to expand services efficiently and cost-effectively.

• Supports the use of flexible policy definitions.

• Integrated with Cisco Catalyst SD-WAN network services, which eliminates the need for any additional hardware.

• Intelligently redirects new flows based on the load on each service node. This also includes the load on individual L7 application accelerators.

• For flows that don't require any optimization, service nodes can inform the AppNav Controller to directly pass-through the packets, thus minimizing the latency and resource utilization.

• Has minimal impact to traffic when adding or removing service nodes.

• Supports VRFs, so that the VRF information is preserved when traffic returns from a service node.

• Supports optimization of asymmetric flows through AppNav controller groups.

  Note

  An asymmetric flow is when the traffic in one direction goes through one AppNav Controller and the return traffic goes through a different AppNav Controller; but both AppNav Controllers redirect the traffic to the same service node.

• Provides inter-router high availability to keep traffic flows uninterrupted, where if one router goes down, the traffic can be re-routed to a different router within the AppNav Controller group.
