Clarification request on rate fields in LMP

["Bradford, Richard" <rbradfor@cisco.com>]

Some different interpretations
for the various rates in LMP messages have come to my attention. These
involve the Minimum
Reservable Bandwidth and Maximum Reservable Bandwidth in a LinkSummary
message.
One interpretation is that the Reservable Bandwidths at least should
represent only the payload portion of the bandwidth. An alternate
interpretation is that all these fields should include all 
overhead.

Let's take the case of a STM-4 Interface, which supports signalling of
individual VC-4 circuits.


Position 1: Raw bandwidth should be used so the values should be:
 Minimum Reservable Bandwidth = OC-3/STM-1   (155.52
Mbps)
 Maximum Reservable Bandwidth = OC-12/STM-4  (622.08 
Mbps)

Position 2: Since for SDH the TDM circuits will be signalled either as
individual VC-4s or as a single VC-4-4c, therefore the values should
be:

 Minimum Reservable Bandwidth = VC-4 (149.760 Mbps)  
 Maximum Reservable Bandwidth = VC-4-4c (599.040 Mbps)

Other interpretations?
