The network plugin integrates the independent arknet library with ark’s message framing, session IDs and Update-thread business callbacks.

net defines start, shutdown, send and Update operations. Application messages retain their existing headers. RUDP uses arknet’s compatible ARQ wire format with FEC disabled by default.
See network builds and tests, ark::net and the arknet protocol guides.
Initial application receive buffer
TCP, WebSocket and RUDP endpoints use a 4 KiB initial application receive buffer and grow as needed. Call set_initial_receive_buffer_size(bytes) on the network object before start_client or start_server; get_initial_receive_buffer_size() reads the configured value. Zero or a change while the endpoint is working returns false; existing sessions retain their selected capacity.
This is the framing buffer for application messages, configured separately from kernel socket send/receive buffers. It is not a 4 KiB maximum message size. The local receive-buffer report retains the allocation, fragmented-input and large-batch throughput tradeoff. It does not establish network RTT or connection capacity.
