[comp.unix.questions] Reliable UDP transport

john@wekiwa.uucp (John Carter) (03/20/91)

I am working on an application which will require a Sun workstation to 
communicate with an external device via UDP.  We need to implement some
simple means of reliability (hopefully nothing too fancy).  If anyone can
point me to a publication or even sources, it would be greatly appreciated.

Please respond via email, as I have a limited news feed here.

Thanks in advance

John

If you need reliability, you have selected the wrong protocol.  If you
selected ("required"?) UDP for it's "light-weight-edness" then you
missed the point.  Rolling your own reliability in user-space will be
more expensive than getting the kernel to deliver your bytes reliably
over TCP.
