Overview: Network boundaries
Network boundaries constrain routes, visibility and forwarding across interfaces or execution environments.
A guest network, VLAN, container namespace or second interface can change the path an application sees. Multicast adds its own forwarding and listener relationships. This area identifies the boundary involved so a successful connection on one side is not treated as evidence of the same access on another.
Guest network isolation
Guest isolation applies a network’s chosen policy to guest clients and destinations, allowing internet access without necessarily permitting local media-server or discovery paths.VLANs
A VLAN identifies a bridged network context through port and tag handling, with routing and policy required for communication between separately defined realms.Multicast routing
Multicast delivery uses receiver membership and forwarding context to copy group traffic onto selected paths, with link-local discovery retaining its own scope rules.Container network modes
A container’s network mode selects the namespace and forwarding relationship that owns its service listener, with published ports and discovery behavior depending on the actual implementation.Multiple network interfaces
Multiple network interfaces add address, listener, route and advertisement choices whose independent selection determines the server path seen by each client.
