Raw

raw-nio

Network applications based on Java raw nio.

  • Java 8 11 17

Event Loop

This is my implementation of the event loop, and I built multiple applications on the event loop.

  • echo
  • TLV protocol(type-lenght-value)
  • load balancer
    • random
    • round robin
    • min connection count
  • HTTP/1.1 server
    • to-do: chunk and trailer

I also implemented an object pool ByteBufferPool to reuse DirectByteBuffer.

TCP Load Balancer

Example

java -cp build/libs/raw-nio-all.jar \
    com.github.gcnyin.rawnio.loadbalancer.LoadBalancer \
    8080 localhost:8081,localhost:8082 roundRobinPool

8080 is the load balancer port. localhost:8081,localhost:8082 is the backend server list, roundRobinPool is the load balancer strategy, also can be minConnectionCountPool and randomPool.

HTTP/1.1 Server

Example

java -cp build/libs/raw-nio-all.jar \
    com.github.gcnyin.rawnio.http1.HttpServer 8080

8080 is the HTTP/1.1 server port.
