Hi ,
I have some question about ASR9K MOD80 LineCard :
1. What is the max performance ? 80Gbps.
Does it means 40Gbps in + 40Gbps out = 80Gbps
or it means 80Gbps in + 80Gbps out ?
That is , if I have MPA -4X10GE *2 in MOD80.
I can have 10GE rate in and out for the 8 10GE port ?
2. some one give a pdf file , it show :
1-Port 40-GE MPA (A9K-MPA-1x40GE, 160 Gb/s throughput version only)
Does that mean MPA-1X40GE can not install on the MOD80 ? or it is
3. What is the MOD80 performance for packet per second ?
if the answer is X pps.
it means Xpps (in) + Xpps(out)
or it mean total(in) + total(out) = X pps
4. What is the mean 440pps ?
One RSP440 moudle has only 220Gbps or 440 Gbps.
220Gps is 220Gbps(in)+220Gbps(out) or in+out=220Gbps?

Michael

hi michael,
MOD80 has 2 NPU's of type Typhoon. A Typhoon NPU can do 45Mpps @60Gbps (for each direction).
So theoretically, a MOD80 can drive 120G worth of bandwidth, but there is no MPA available that exploits that. the MOD80 can take as highest density MPA the 4x10G or the 1x40G.
You can use the 1x40G in the MOD80.
The only 2 MPA's that specifically require a MOD160 (which has 4 NPU's, 2 per bay) is the:
8x10G and 2x40G MPA's.
The RSP440 provides for 220G per slot per direction worth of fabric badnwidth.
Each slot receives 4 SERDES lanes @55G each.
If you have dual RSP's then you get 220+220=440 per slot per direction.
The RSP440 was called 440 because it provides 440G total per slot (or 220 per direction).
this is irresspective of packets per second.
If you like more detail on this topic pull the cisco live preso's that have a lot of detail on the architecture and troubleshooting details.
cheers!

Hi Alexander,
Thanks for your answer.
I just want to verify
45Mpps @ 60Gbps( for each direction).
Does that mean A NPU concurrent can do 45Mpps (IN) +45Mpps (OUT) = 90Mpps?
or
MOD80 can be linerate (@128byte) for total 8 port 10GE , 80G in + 80G out ?
Regards,
Michael

Hi Michael,
correct 45 in and 45 out, so 90 total.
so MOD80 can carry 8 10G's, but over 2 bays. You'll be using the 4x10G MPA and two thereof.
at the max pps rate of 45Mmps, the packetsize at 40G is 110 bytes.
