Re: 9.584640 (framing issue)


I believe that the framing solution is a second-order task and that the first
order task is to determine if there is any possibility of supporting an
Ethernet stream, consisting of variable sized packets at ANY MAC/PLS data rate
which would eliminate any flow control requirements between Ethernet and SONET

Is 9.584640 Gbps this data rate? If not, is there any data rate that meets the
above requirement? If not, the HSSG speed objective should be 10.0 Gbps.

Best Regards,
