I'm new the world of TCP / IP, Networking, Sockets etc.. during my internship I should replace the Nanomsg Library with java-only code. My supervisor has also sent me the following protocol and wants me to write a implement it: https://github.com/nanomsg/nanomsg/blob/master/rfc/sp-tcp-mapping-01.txt .
So here are some questions that still arise in my mind:
- The written code should be executed once the connection has been established. do you have any suggestions how I can do this ? I have tried it but I am not sure if that will work, here is what I have done:
`public void connectionInitiation(AsynchronousSocketChannel connectReq, AsynchronousSocketChannel connectionPair) {
if(connectReq)
Future<Integer> writeBytes = connectReq.write(header);
writeBytes.get();
ByteBuffer receivedbytes = ByteBuffer.allocate(4);
Future<Integer> readBytes = connectionPair.read(receivedbytes);
header.flip();
receivedbytes.flip();
if (!header.equals(receivedbytes)) {
connectReq.close();
} else if (receivedbytes.get(6) != 0x00 || receivedbytes.get(7) != 0x00) {
connectReq.close();
} else {
System.out.println("Protocol Header is successfully verified.");
}
}`
this method comes right after the connection has been established.
- He asked me to do this in a separated class, how can I do this ? ( sorry if the question is quiet dumb )
I apologize if the questions are not clear enough or if the answer is tooo obvious.... I still in the learning phase and want to make sure I grasped this in the right way.
