Introduction
gnet
is an event-driven networking framework that is fast and lightweight. It makes direct epoll and kqueue syscalls rather than using the standard Go net package and works in a similar manner as netty and libuv, which makes gnet
achieve a much higher performance than Go net.
gnet
is not designed to displace the standard Go net package, but to create a networking server framework for Go that performs on par with Redis and Haproxy for networking packets handling.
gnet
sells itself as a high-performance, lightweight, non-blocking, event-driven networking framework written in pure Go which works on transport layer with TCP/UDP protocols and Unix Domain Socket , so it allows developers to implement their own protocols(HTTP, RPC, WebSocket, Redis, etc.) of application layer upon gnet
for building diversified network applications, for instance, you get an HTTP Server or Web Framework if you implement HTTP protocol upon gnet
while you have a Redis Server done with the implementation of Redis protocol upon gnet
and so on.
gnet
derives from the project: evio
while having a much higher performance and more features.
Features
- High-performance event-loop under networking model of multiple threads/goroutines
- Built-in goroutine pool powered by the library ants
- Built-in memory pool with bytes powered by the library bytebufferpool
- Lock-free during the entire runtime
- Concise and easy-to-use APIs
- Efficient and reusable memory buffer: Ring-Buffer
- Supporting multiple protocols/IPC mechanism:
TCP
,UDP
andUnix Domain Socket
- Supporting multiple load-balancing algorithms:
Round-Robin
,Source-Addr-Hash
andLeast-Connections
- Supporting two event-driven mechanisms:
epoll
on Linux andkqueue
on FreeBSD/DragonFly/Darwin - Supporting asynchronous write operation
- Flexible ticker event
- SO_REUSEPORT socket option
- Built-in multiple codecs to encode/decode network frames into/from TCP stream: LineBasedFrameCodec, DelimiterBasedFrameCodec, FixedLengthFrameCodec and LengthFieldBasedFrameCodec, referencing netty codec, also supporting customized codecs
- Supporting Windows platform with
event-driven mechanism of IOCPGo stdlib: net - Implementation of
