according to the data queried on the Internet, any element in the TCP quad belongs to a different connection. then the assumption that the same client connects to the unreachable ports of different servers is true. Open port 8081 on the server, and try...
A http packet is very large and will be segmented in the tcp layer, that is, it will be divided into multiple tcp packages. If one of the tcp packets is lost and the retransmission fails, will the application layer read the http request? ...
use netty as a message push system and use Web Socket protocol to communicate. Hundreds of thousands of connections are found and a hundred messages are sent during the test. at present, the client connects directly to the server to receive the expecte...

has just realized the communication between two clients (tcp protocol under linux). The implementation idea is very simple, that is, one client sends a message, and the server first read to and then write to another client, and that s it. after caref...
just learned tcp programming under linux, and just successfully implemented a simple backfire client-server. but there is a question: when the client finishes sending the file, it needs close (fd), so how can I tell the server that you can also close ...
how does RT, understand that the TCP IP protocol is data flow oriented and the UDP protocol is Datagram oriented? ...
if a socket between the client and the server is closed (the tcp connection is closed), the client will not be able to re-establish an identical socket in a short period of time (two minutes according to the book). So my understanding is: join me to conn...
