Aspects of the subject disclosure may include, for example, selecting a first video service model according to a server hostname determined according to transport layer security (TLS) transaction data associated with a video session transmitted over a network, calculating a plurality of data delivery statistics from the TLS transaction data according to the first video service model, where the plurality of data delivery statistics includes session-level statistics over the video session, transaction-level statistics over each transaction, and temporal feature statistics over intervals of the video session, determining a quality of experience (QoE) metric for the video session from the plurality of data delivery statistics according to a course-grained data QoE model, and adjusting a first network element of the network responsive to the determining the QoE metric for the video session. Other embodiments are disclosed.

Method and apparatus for estimating quality of experience from network data

In one example, a processing system including at least one processor obtains a transport control protocol flow associated with a video session that streams a video from a server to a client. The transport control protocol flow comprises a plurality encrypted packets exchanged between the server and the client. The processing system then reconstructs a hypertext transfer protocol transaction that is part of the streaming video session. The reconstructing is performed without decrypting the plurality of encrypted packets.

Estimating video quality of experience metrics from encrypted network traffic

A connection procedure for finding by rearrangement a path for multirate, multicast traffic through an SDH cross-connect with subnetwork connection protection. If no free path for a new payload through the SDH switching hardware is available, the switching procedure looks for a path that is adequate and blocked by the least existing payload capacity. If the hunt is successful, the procedure rearranges the existing connections to make possible a path for the new payload. The procedure does not interrupt the existing connections; thus it is a 'hitless' procedure. Connections for existing payloads that must be moved to make way for the new payload are queued and the connection procedure is applied recursively, to each in turn, until the queue is empty.
