Reliable UDP

Anybody can tell me some articles(or links) talking about reliable UDP transmission mechanism. Better formal resolution.
Thanks a lot.

UDP by it's very nature is NOT reliable since it is connectionless.

I would look into articles on VOIP ( voice over IP ) and other stuff for more details.

I hope this helps !

There's a spec out for Reliable UDP called RDP. Given the problems that a couple of the firewall vendors have encountered it may be awhile before it's widely implemented. Search the internet for RDP and you'll find some technical detail. Cisco calls it RUDP or Reliable User Datagram Protocol.

SysExpert: "Connectionless" is short hand for "not connection oriented" which is different from unreliable. You are correct that UDP cannot rely on itself to insure reliable data delivery  . . . which is why applications that avail themselves of UDP often include their own form of integrity checking . . . TFTP for example.

Good luck.

You have asked 21 questions here at EE, and you have only resolved 3 of them. Here is a list of your open questions. I will be posting this comment in all of them.

To assist you in your cleanup, I'm providing the following guidelines:

1.  Stay active in your questions and provide feedback whenever possible. Likewise, when feedback has not been provided by the experts, commenting again makes them receive an email notification, and they may provide you with further information. Experts have no other method of searching for questions in which they have commented, except manually.

2.  Award points by hitting the Accept Comment As Answer button located above and to the left of that expert's comment.

3.  When grading, be sure to read:
to ensure that you understand the grading system here at EE. If you grade less than an A, you must explain why.

4.  Questions that were not helpful to you should be PAQ'd (stored in the database for their valuable content?even if not valuable to you) or deleted. To PAQ or delete a question, you must first post your intent in that question to make the experts aware. Then, if no experts object after three full days, you can post a zero-point question at community support to request deletion or PAQ. Please include the link(s) to the question(s).
At that point, a moderator can refund your points and PAQ or delete the question for you. The delete button does not work.

5.  If you fail to respond to this cleanup request, I must report you to the Community Support Administrator for further action.

Our intent is to get the questions cleaned up, and not to embarrass or shame anyone. If you have any questions or need further assistance at all, feel free to ask me in this question or post a zero-point question at CS. We are very happy to help you in this task!
