+# QUIC implementation {#rdma_doc}
+
+The quic plugin provides an IETF QUIC protocol implementation. It is based on
+the [quicly](https://github.com/h2o/quicly) library.
+
+This plugin adds the QUIC protocol to VPP's Host Stack. As a result QUIC is
+usable both in internal VPP applications and in external apps.
+
+
+## Maturity level
+Under development: it should mostly work, but has not been thoroughly tested and
+should not be used in production.
+
+
+## Features
+ - only bidirectional streams are supported currently.
+
+
+## Getting started
+
+QUIC constructs are exposed as follows:
+
+- QUIC connections and streams are both regular host stack sessions.
+- QUIC connections can be created and destroyed with regular `connect` and
+  `close` calls with `TRANSPORT_PROTO_QUIC`.
+- Streams can be opened in a connection by calling `connect`again and passing
+  the ID of the connection to which the new stream should belong.
+- Streams can be closed with a regular `close`call.
+- Streams opened by peers can be accepted from the sessions corresponding to
+  QUIC connections.
+- Data can ba exchanged by using the regular `send` and `recv` calls on the
+  stream sessions.
+
+Example code can be found in:
+`src/vnet/session-apps/echo_client.c`: Test client using the internal API
+`src/vnet/session-apps/echoo_server.c`: Test server using the internal API
+`src/tests/vnet/session/quic_echo.c`: Client and server, using the external API
