First, how to implement server-side framework
For the server, the problem to be solved are:
1, how to access and communicate more devices;
2, for accepting the connection is in what way? Asynchronous, synchronous, blocking or obstruction charges;
3, how to make this program more robust to ensure the long-run?
4, the issue of multi-threaded;
Second, on the encoder and the decoder issues
Third, on the communication protocol
1, the communication process, the client is to receive packets (binary stream) is converted into an object, the object is then received post service logic processing object converted to the feedback packet (binary stream) process;
Remaining problem:
1 and the relationship between channelread channelread0,;
2、ByteToMessageDecoder
ChannelInboundHandlerAdapter
SimpleChannelInboundHandler
fireChannelRead
to be continued. . .
