The processor in the CAT depends on the MSFC version, either 1, 2 or 3 but
it's based on 7500 RSP CPUs. The processor is used for process switching and
depending on the sup NAT, DLSW etc. For normal traffic flows almost all the
packet switching will be done in hardware which is why it can do 6Mpps (The
new Sup 720(MFSC 3) can do 400Mpps). The 7600/CAT also supports interfaces
that the 7200 cannot (e.g. 10G Ethernet) which is why it is higher up the
product range.
If you need high bandwidth then the CAT is much more powerful.

Subject: OT: 6509 or 7200, which is better for border router?
Hello,
I'm in a process of designing a data centre. I got several 7200vxr and 6509
at my disposal.
1. What kind of cpu is 7200 running? NPE400 or R7000?
2. If both 6509 and 7200vxr are running R7000 CPU, then 7200vxr seems better
from an old-fashioned router point of view (because it's running at 350Mhz,
while 6509 is at 300Mhz). But 6509's RP is actually a 7600 router, how can
it be slower than 7200?
3. From CCO, I got:
NPE-400 - performance up to 400 Kpps ---------for 7200
Service Performance 6 Mpps--------------for 7600
Does this mean 6509 is 1500 times faster that 7200 when they are doing
packet switching?
4. 6509's strongest point is MLS, is this feature important in a border
router? 6509 or 7200, which is better for a border router's role?
Many thanks,
Weidong
