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.

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.
