Module transport 

Reliable UDP transport layer.

Builds reliable, ordered delivery on top of raw UDP without any async runtime. Drive the stack each frame by calling ConnectionManager::poll().

Architecture

 Application
     │  send(channel, data)
     ▼
 ConnectionManager  ──  maintains one Connection per peer

 Connection  ──  per-channel send queues + ReliableUdp
     │

 NonBlockingSocket  ──  wraps std::net::UdpSocket

Structs

ConnectionManager

Manages multiple UDP peer connections over a single local socket.

Fragmenter

Splits large payloads into MTU-safe fragments and reassembles on the receiver side.

NonBlockingSocket

Non-blocking UDP socket wrapper with poll-based receive.

ReceivedPacket

A packet received from a specific peer, ready for the application layer.

ReliableUdp

Reliable ordered UDP transport for a single peer connection.

TransportStats

Snapshot of transport-layer statistics for a single peer connection.

Enums

Channel

Delivery channel semantics for outgoing data.

ConnectionState

Lifecycle state of a single UDP connection to a remote peer.

Constants

ACK_WINDOW

Number of sequence numbers in the ack window.

FRAGMENT_TIMEOUT_MS

Fragment timeout in milliseconds (drop partial reassembly).

JITTER_ALPHA

EWMA smoothing factor for jitter.

KEEPALIVE_MS

Keepalive interval in milliseconds.

MAX_RETRANSMIT

Maximum number of retransmit attempts before giving up.

MTU

Maximum Transmission Unit for outgoing packets (bytes).

PEER_TIMEOUT_MS

Peer timeout after last received packet (ms).

RETRANSMIT_BASE_MS

Base retransmit timeout in milliseconds.

RETRANSMIT_MAX_MS

Maximum retransmit timeout after backoff (ms).

RTT_ALPHA

EWMA smoothing factor for RTT estimation.
