Namespace VpnHood.Core.Tunneling

GeneralEventId: Provides the event IDs of VpnHood's log lines, by what a line is about.

ThrottledTunnel: Represents a tunnel with a send limit: the session's packets wait in its queue, one for all its channels, and leave it at the limit.

TrafficMeter: Tracks tunnel traffic as two independent directions, and holds the session's speed limit: one bucket per direction, which every path of the session charges, so the limit covers all of its traffic. A sender waits on it once per turn (the tunnel's queue for its packets, each forwarding stream for its reads), so its senders share it equally; a receiver only enforces it, slowing a stream or dropping a datagram the peer sent past the limit. For session-facing limits, server download maps to send and server upload maps to receive.

Tunnel: Represents a session's tunnel: it passes each packet straight on, to its UDP channel while UDP is on and otherwise to one of its stream channels, and hands up what either receives.
