Thinking your explanation, I understand all HDLC frames are delivered
over HDLCPWs in order to maximize transparency, so that they any
protocol that has HDLC-like framing may utilize the HDLCPW mode,
including PPP, Frame-Relay ("port to port" Frame-Relay transport), X.25
(LAPB), etc. This is an advantage, but delivering all frames (including
RR, RNR, ...) is less efficient for the bandwidth.
On the other hand, in FRPW is necessary to inspect a frame incoming on
So, if you need a solution for a particular scenerio (i.e. LAPB over
IP), would it be better (more efficient) to define an specific PW for
this particular protocol that has HDLC-like framing?. For instance, a
LAPB PW which only deliveres over PWs the necessary frames (usually, I
