Overview: Networking and remote access

Media networking connects addressing, routing, transport security, delivery performance and the access policies applied to a request.

Reaching an Emby server involves several decisions before playback begins: finding its address, choosing a route, establishing the connection and presenting acceptable identity evidence. Continuing playback then depends on the rate and consistency of data delivery.

The topics below distinguish home-network behavior from remote reachability, and connection security from user authorization. Performance and network-boundary pages explain why a reachable server can still have a slow stream or an isolated client. Keeping those questions separate makes each observed failure more informative.

• Home network fundamentals
  Home-network fundamentals connect addressing and transport with the local or remote route a media request uses.

• Names and discovery
  Network names and discovery mechanisms help an application find the destination it needs to contact.

• Routers and remote reachability
  Router and intermediary behavior determines how a request reaches the server and what its successive connection legs mean.

• Connection security
  Connection security relates protected transport, endpoint identity and browser-enforced request boundaries.

• Network performance
  Network performance describes useful delivery over time through the links and shared resources carrying a stream.

• Network boundaries
  Network boundaries constrain routes, visibility and forwarding across interfaces or execution environments.

• User identity and access
  Media-server access connects accepted identity and session state with the rules governing requested resources.
