# Features

Choose a transport by its message semantics and peer requirements, or a native
service client by its protocol. Transport endpoints share lifecycle, owned-send
and IO scheduling conventions; service clients document their request and reply contracts.

## Availability

- Boost.Asio is the default dependency. Standalone Asio supports TCP, UDP, RUDP,
  TLS and database clients through the same callback API; HTTP and WebSocket require Boost.Beast.
- MySQL authentication and secure transports require `ARKNET_ENABLE_SSL` and OpenSSL.
- IPv4 and IPv6 share the endpoint API; listening policy is explicit.
- HTTP currently implements HTTP/1.1. Native UDP does not add retransmission or segmentation.
- RUDP includes ARQ-only, fixed FEC and adaptive FEC in `v0.1.0`; local validation is complete. See [deployment acceptance](/arknet/project/production-readiness).
- [Single HTTP requests](/arknet/features/http/requests) support completion, timeout and cancellation.
- Public coroutine endpoints, HTTP/2, HTTP/3, named pipes, Unix domain sockets,
  RPC, DTLS and WebSocket compression are [planned](/arknet/project/roadmap).
- The [database client guide](/arknet/features/database-clients) covers native single-node MySQL
  and Redis clients, exclusive pool leases and failure handling.
