Flow-based Performance Measurement
... IP Performance Monitoring based on flow/applications is needed in many cases. For mobile operator’s backhaul network, the applications are devided into multiple bearers with proper mobile QoS parameters (e.g. QCI). If the mobile network would manage bearers as QoS and applications, then the performa ...
