udp error detection
Posted on 2004-04-06
just a few quick question im not too sure in how this works:
UDP isnt connection orientated... correct?
UDP offers no Error detection......correct?
Design and Specify an Application Level Single-Shot-Protocol that will provide reliable delivery of individual single component messages over IP networks.
1. i was thinking about
firstly a timeout? but as i am a complete begginer how would i calculate an appropriate
time to time out! i really have very limited knowledge so please explain everything ie
2. also the extra protocol that im designing would appear in the Application level? is that
3, also when passing packets how would the end user know that they havent recieved a
packet because from wat i can gather UDP doesnt number the packlets like TCP. Would i
have to do this in the protocol im designing or is there a way around this.
4. How does the header work in UDP? is there any extra bites that could be used to pass info
around to help in error detections
5. or am i completely wrong! if so please help!
6. and one last Q WHAT IS A SINGLE SHOT PROTOCOL?
CAN SUM1 PLEASE TELL ME WHERE TO START WITH THIS AND HOW I SHOULD GO ABOUT THIS!
