what is overhead, payload, and header - Stack Overflow The packet like you said, has the "payload" which is the data itself it needs to transfer (usually the user's data), the "header" contains various things depending on the protocol you are using, for example UDP contains just simple things in the header like Destination and Source IP PORT, TCP on the other end contains more things like the sequence number of the packet to ensure ordered
What are examples of TCP and UDP in real life? - Stack Overflow UDP is a connectionless protocol - it simply has a destination and nodes simply pass it along if it comes as best as they can So packets arriving out of order, along various routes etc are common So Instant messengers and similar software developers think UDP an ideal solution
UDP Networking Fundamentals - Stack Overflow I've been doing some work with C# Networking using UDP I'm getting on fine but need the answer to a couple of fundamental questions I'm having problems testing: Currently I'm sending data in a ~16000 byte datagrams, which according to wireshark is getting split into several 1500 byte packets (because of max packet size limits) and then
When is it appropriate to use UDP instead of TCP? [closed] Comparing TCP with UDP, connection-less protocols like UDP assure speed, but not reliability of packet transmission For example in video games typically don't need a reliable network but the speed is the most important and using UDP for games has the advantage of reducing network delay
TCP stream vs UDP message - Stack Overflow UDP, on the other hand, is a packet-oriented protocol where the application such as Java class java net DatagramPacket; java net DatagramPacket; import java net DatagramsSocket creates a packet first before talking to UDP, and the packet is sent out with additional information by UDP IP protocols to the server side
How to do Network discovery using UDP broadcast - Stack Overflow It's just sends one single UDP package with specified data to 255 255 255 255 - to the broadcast address of local network If there is no any "smart hardware"(like routers) between your computer and server, then it must response to this package
UDP vs TCP, how much faster is it? - Stack Overflow @PSIXO: Well, TCP and UDP serve different application requirements, so both are used by applications The implication of your suggestion is that we should have different networking infrastructure for TCP and UDP traffic - an expensive proposition, and certainly not something we can do now, especially with all the investment already done
UDP Client Server Socket in Python - Stack Overflow # We will need the following module to generate randomized lost packets import random from socket import * # Create a UDP socket # Notice the use of SOCK_DGRAM for UDP packets serverSocket = socket(AF_INET, SOCK_DGRAM) # Assign IP address and port number to socket serverSocket bind(('', 12000)) while True: # Generate random number in the range
