As virtual network functions increasingly run on compute nodes, having efficient monitoring to manage the health of virtual networks has become a key requirement. Traditional monitoring methods are no longer scalable in distributed data plane models and new methods must be developed to offer greater scale without compromising programmability and flexibility. Using IO Visor, high performance monitoring can be achieved for operations and management. Join the session to find out about IO Visor and how it can be used for scalable monitoring of virtual network functions. The talk will also cover using IO Visor to evolve Virtual Network data plane and to enable hardware accelerations.
