Best Practices for End-to-End Workflow Monitoring
As the video streaming industry continues to mature, QoE expectations continue to rise in importance both as a value proposition to the consumer as well as a differentiator between competing video streaming services. Yet, consistent, systematic, standardized, objectively measured, and business-rules-driven QoE assurance continues to be an elusive goal. This document outlines factors that impact consumer QoE, sheds light on some of the underlying challenges to diagnosing QoE impact and provides a set of best practices for end-to-end QoE monitoring in video streaming workflows.
Key Network Delivery Metrics
This document describes key network delivery metrics for streaming Internet video. The Streaming Video Alliance Quality of Experience (QoE) working group (WG) developed these metrics as a common language to describe effectiveness of network delivery. Although many more metrics could have been documented, these particular metrics represent the most common and important metrics according to the QoE WG group membership. It is expected that these metrics can be used across the streaming video ecosystem to provide guidance that can lead to enhancement of QoE.

SVTA Distributed Tracing: Working Towards Improved Observability and QoS/QoE
As the streaming tech stack has grown in complexity, ensuring a high-quality viewing experience has become increasingly challenging. Part of that is the nature of a distributed architecture frequently assembled from third party services and technologies as well as just more moving parts. But part of it is also a lack of well-established standards which meet the specific needs of streaming content providers. The combination of these two issues results in operational “blind spots” when tracing issues through the workflow. Because of the critical importance of data within streaming operations, any blind spots can significantly increase the Mean Time to Diagnose (MTTD) and, more importantly, the Mean Time to Resolve (MTTR). When these operational streaming metrics go up, QoE and viewer satisfaction goes down often resulting in loss of revenue and/or increased churn. There is a need then, for a standardized approach to trace data across the different vendors in the streaming video technology stack with an obvious starting point: CDNs.
