[AusNOG] back of envelope sizing calculations

[Skeeve Stevens]

7200-G1 - 512mb mtp (max throughput)
7200-G2 - 1024mb mtp

They have 3 * GE

2851 with an extra GE would be pushing it with 112mb mtp

3825 - need two extra gig ports - 179 mtp
3845 - need two extra gig ports - 256 mtp

A G1 which can either be in 7200 form or 7301 form.

A G2 can be in 7204/6 form or 7201 form.

HWIC-GE cards are more expensive that PA-GE's.

My recommendation is a 7204VXR-NPE-G1 for cost, expandability (can go to 4 GE - maybe 5 if the bandwidth points aren't counted from slot 0 NPE), or a G2 if you can afford it.
