Netty (software)
open-in-new
<p>Netty is a <a href="/facts/Non-blocking_I%2fO/6A7V3P89">non-blocking I/O</a> client-server <a href="/facts/Software_framework/EWasA8sG">framework</a> for the development of <a href="/facts/Java_(software_platform)/fpn6x8WL">Java</a> network applications such as protocol servers and clients. The asynchronous <a href="/facts/Event-driven_programming/QlGL2Fu6">event-driven</a> network application framework and tools are used to simplify <a href="/facts/Computer_network_programming/lG6r58eY">network programming</a> such as <a href="/facts/Transmission_Control_Protocol/WW4sPrt9">TCP</a> and <a href="/facts/User_Datagram_Protocol/dxLU0D6q">UDP</a> socket servers. Netty includes an implementation of the <a href="/facts/Reactor_pattern/svHjSFHw">reactor pattern</a> of programming. Originally developed by <a href="/facts/JBoss/sdwoM5jn">JBoss</a>, Netty is now developed and maintained by the Netty Project Community. </p><p>Besides being an asynchronous network application framework, Netty also includes built-in implementations of <a href="/facts/Secure_Sockets_Layer/pGy16TnA">SSL</a>/<a href="/facts/Transport_Layer_Security/pGy16TnA">TLS</a>, <a href="/facts/HTTP/TWtvf7JD">HTTP</a>, <a href="/facts/HTTP%2f2/L7V7rfeP">HTTP/2</a>, <a href="/facts/HTTP%2f3/SUASQpzB">HTTP/3</a>, <a href="/facts/WebSocket/NcQrqpnv">WebSockets</a>, <a href="/facts/DNS/rfxdWFsj">DNS</a>, <a href="/facts/Protocol_Buffers/4Pj3zymo">Protocol Buffers</a>, <a href="/facts/SPDY/2uH2Rbu5">SPDY</a> and other protocols. Netty is not a Java <a href="/facts/Web_container/Pv06YKvB">web container</a>, but is able to run inside one, and supports message <a href="/facts/Data_compression/gMFuY4FT">compression</a>. Netty has been actively developed since 2004. </p><p>Beginning with version 4.0.0, Netty also supports the usage of <a href="/facts/New_I%2fO/jYxQBatx">NIO.2</a> as a <a href="/facts/Front_and_back_ends/QVUfH8gu">backend</a>, along with <a href="/facts/New_I%2fO/jYxQBatx">NIO</a> and blocking Java sockets. </p>
