1. TCP(Transmission Control Protocol). TCP is a
connection-oriented protocol, a connection can be made from
client to server, and from then on any data can be sent
along that connection.
* Reliable - when you send a message along a TCP
socket, you know it will get there unless the connection
fails completely. If it gets lost along the way, the server
will re-request the lost part. This means complete
integrity, things don't get corrupted.
* Ordered - if you send two messages along a
connection, one after the other, you know the first message
will get there first. You don't have to worry about data
arriving in the wrong order.
* Heavyweight - when the low level parts of the
TCP "stream" arrive in the wrong order, resend requests have
to be sent, and all the out of sequence parts have to be put
back together, so requires a bit of work to piece together.
2. UDP(User Datagram Protocol). A simpler message-based
connectionless protocol. With UDP you send messages(packets)
across the network in chunks.
* Unreliable - When you send a message, you don't
know if it'll get there, it could get lost on the way.
* Not ordered - If you send two messages out, you
don't know what order they'll arrive in.
* Lightweight - No ordering of messages, no
tracking connections, etc. It's just fire and forget! This
means it's a lot quicker, and the network card / OS have to
do very little work to translate the data back from the packets.
