UDP and TCP Comparison of Transport Protocols
UDP and TCP Comparison of Transport Protocols
You have most likely heard of sockets, and are probably aware that there are two main types: TCP and UDP. When writing a network game, we first need to choose what type of socket to use. Do we use TCP sockets, UDP sockets or a mixture of both?
TCP ( Transmission Control Protocol )
- Connection based
- Guaranteed reliable and ordered
- Automatically breaks up your data into packets for you
- Makes sure it doesnt send data too fast for the internet connection to handle (flow control)
- Easy to use, you just read and write data like its a file
UDP ( User Datagram Protocol )
- No concept of connection, you have to code this yourself
- No guarantee of reliability or ordering of packets, they may arrive out of order, be duplicated, or not arrive at all!
- You have to manually break your data up into packets and send them
- You have to make sure you don�t send data too fast for your internet connection to handle
- If a packet is lost, you need to devise some way to detect this, and resend that data if necessary
