Zusammenfassung:	Computer-implemented systems and methods for diagnosing and correcting connectivity problems in a network are provided. The method includes obtaining, at a network node disposed at an edge of the network, measurements of one or more attributes of network traffic exchanged between a content server and a client device via the network. The network traffic is associated with streaming video content transmitted from the content server to the client device over the network. The method also includes analyzing the one or more attributes of the network traffic to estimate Quality of Experience (QoE) performance metrics related to the streaming video content at the client device, and adjusting one or more network operating parameters of the network responsive to QoE performance metrics falling below a predetermined threshold.
