问题 Someone told me That Serialization was not the best way to send things over a socket but they said they read that in a book once and was not sure of a better way cause they haven't really done networking before. so is Serialization the best way or is there a better way. Also this is for a game if that makes much of a difference. What i see by searching questions about sending objects over it looks like most people use Serialization but im just checking to see what people thing 回答1: To

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 Right now, I'm trying to write a GUI based Java tic-tac-toe game that functions over a network connection. It essentially works at this point, however I have an intermittent error in which several chars sent over the network connection are lost during gameplay. One case looked like this, when println statements were added to message sends/reads: Player 1: Just sent ROW 14 COLUMN 11 GAMEOVER true Player 2: Just received ROW 14 COLUMN 11 GAMEOV Im pretty sure the error is happening when I read

问题 I have a function that reads an XML page from a device attached to the network. The page is reached via url. The problem I'm having is that if I remove the device from the network while the function is parsing the XML page, the code freezes forever. How can I break out of the function if this happens? This is the code (the function returns a list of tags <example> ): public static List<string> GetTags(string xmlLocation) { //xmlLocation = http://192.x.x.x/xmlpage List<string> dataList = new

问题 I’m writing a traffic generator in C using the PACKET_MMAP socket option to create a ring buffer to send data over a raw socket. The ring buffer is filled with Ethernet frames to send and sendto is called. The entire contents of the ring buffer is sent over the socket which should give higher performance than having a buffer in memory and calling sendto repeatedly for every frame in the buffer that needs sending. When not using PACKET_MMAP, upon calling sendto a single frame is copied from
