a PVC is connection oriented - by definition - otherwise the virtual circuit won't stay up.
data flow, OTOH, is connectionless - packet delivery is "best effort" Clear as mud?

I'm still studying to get my CCNA certification, and i have some doubts related to frame-relay protocol. Is it connection-oriented or connectionless? I know it's is a stupid question, however, i found two answers on the net. "CONNECTIONLESS, Packet-Based Protocol" http://www.gdc.com/corporate_news/connects04/techfocus/framebasics.html and "Frame Relay provides CONNECTION-ORIENTED data link layer communication" http://www.cisco.com/univercd/cc/td/doc/cisintwk/ito_doc/frame.htm So... what is the right one?
