[c-nsp] OSM-1OC48-POS-SS(+) for 7600/6500

[sandmaier at schlund.net]

Hi all,

does anybody know what the differences are between OSM-1OC48-POS-SS and 
OSM-1OC48-POS-SS+ ?

AFAIK the differences only concern QoS.

I'm not sure if my assumptions are true:

The OSM has a 8 GBps uplink in the Sup-SF and use the PFC for the 
forwarding decision (IPv4/6/MPLS) and QoS marking/policing, while PXF is 
used for queuing/scheduling. Not sure if LLQ, CBWFQ, WRED is completely 
unsupported on the !+ or if there are only limitations.

Is this historically with the exception of the queuing/scheduling stuff?:
OSR were originally designed for the 7600OSR and used this PXF (parallel 
xpress forwarding) directly on the linecard for forwarding and 
everything else. The enhanced version has for PXF double Route Table 
Memory and Packet Processing Memory and 4 times Backet Buffer, 6Mpps to 
3Mpps throughput, more queues and VRFs and enhanced QoS (LLQ, CBWFQ, WRED).

Thanks,
Jan
