Marek,
Can you spell out the precise benefits of extending the MPCP domain across to coax?
Is an unified OAM domain not enough to guarantee transparent provisioning between optical and coax without the need for OLT changes?
MPCP is a one dimensional (i.e., time-based) access control scheme. Mandating it on coax will rob us of the ability to account for the frequency selectivity
of the RF medium, and the aforementioned “chunkiness” of spectrum availability.
Lastly, regarding the rate adaption and packet filtering functions that you mention the OCU potentially having to perform, how would you characterize these
changes if not MAC changes?
Alex
