udp

问题 I'm writing a Network Framework prototype in Java using UDP to deal with moments where a device using it might not have a permanent and/or reliable connection and how it should deal with it. It is required that I have to be able to use it with "normal" IPv4 and IPv6 addresses as well as IPv6 LinkLocal Addresses. Due to the concept there's moments where the device loses connectivity and i have to close all DatagramSockets binded to a specific IP/Port pair so i can free resources and, once the

问题 Hello I'm currently running code that sends data from Python to JavaScript. Currently, because I'm not able to send data straight from the primary code I'm running, I am communicating between UDP Connections across two separate Python Files: I merged UDP Server Code with the Main Code I'm running which is an OpenCV Eye Coordinate Tracker. This UDP Server carries the Eye Coordinate data and sends it to the UDP Client which I have merged with the Websocket Server that is communicating with a

问题 [SOCKET PROGRAMMING] [UDP SERVER] I am trying to do Message encryption and decryption using UDP server. Code is here: https://www.geeksforgeeks.org/message-encryption-decryption-using-udp-server/ But I am getting the following error: fatal error: netinet/in.h: No such file or directory How to resolve this issue? 回答1: For the socket stuff on Windows you need #include <winsock2.h> and you will also need to link with -lws2_32 . In the beginning of your program you will also need to initialize

问题 This question already has answers here : The most reliable and efficient udp packet size? (4 answers) Closed 8 months ago . Can UDP packet be fragmented to several smaller ones if it exceeds MTU? It seems that MTU fragmentation is about IP layer so I think it can. If so, what is the recommended max. packet size to send over UDP to avoid fragmentation and why? 回答1: Any IP datagram can be fragmented if it is larger than the MTU. Whether it contains UDP, TCP, ICMP, etc. does not matter. Most
