Good timing - we just had this conversation a couple of weeks ago. :-)
There's a difference between a protocol being connection-oriented and it
being reliable. The two are not related.
Frame Relay is connection-oriented in that it establishes a connection
between endpoints *before* any data is sent. However, Frame Relay is
unreliable in that it does not perform any checks to make sure that every
frame sent is received by the other end. Frame Relay relies on upper-layer
protocols (eg TCP) to perform this function.

Subject: Frame Relay Definition [7:57439]
I've been trying to clear something up about frame relay. Two books I've
read say it is connection-oriented. But they also say there is no guarantee
of delivery, best effort, etc. I thought the difference between
connection-oriented vs. connectionless was pretty clear cut, so this seems
to be contradictory. One book said something vague about the virtual
circuits making it connection-oriented.
Can anyone make sense of this?
Thanks.
