Overview: Network performance
Network performance describes useful delivery over time through the links and shared resources carrying a stream.
A negotiated link rate, a useful throughput measurement and a delayed packet describe different observations. Wireless conditions and traffic queues can change those observations while the destination remains reachable. This branch connects delivery quality, link types and measurement to the timeline a media player depends on.
Capacity and delivery quality
Delivery capacity and quality describe data rate, delay, variation and loss in the direction a media operation uses.Wireless links
Wireless link behavior depends on radio conditions, frequency use and the paths sharing available airtime.Ethernet link speeds
Ethernet link speed describes negotiated link-layer operation, while frame overhead, duplex and slower intermediate links determine its relationship to useful end-to-end media delivery.Powerline networking
Powerline networking carries data over electrical wiring through a shared channel whose usable rate depends on the supported PHY/link family and changing path conditions.Congestion and traffic management
Congestion and traffic management describe how shared demand creates queues and how delivery is scheduled.Measuring network capacity for streaming
A streaming-capacity measurement must use the intended endpoints, direction, protocol and workload, retaining interval and receiver-side progress before testing the actual Emby presentation.
