Abstract
Disclosed are systems, methods and computer program products for measuring and reducing latency of radio link flows having different quality of service (QoS) reservations. An example method comprises establishing one or more radio link flows with an access gateway, wherein each radio link flow has a different QoS reservation, transmitting at least one transport layer protocol message having a predetermined size on each radio link flow to the echo service of the access gateway, receiving at least one response message on each radio link flow from the access gateway, computing the round trip time (RTT) for the transmitted and received messages on each radio link flow, and modifying QoS reservations of the one or more radio link flows based on the computed RTT for the one or more radio link flows.
