[c-nsp] carrier router models comparison

[Emanuel Popa]

hi tassos,

i'm really scared when using a fairly new platform with a fairly new
software version. i would prefer paying more money for a more stable
device. and this fear of mine goes back to the SRB2 version for the
Cisco 7600 which is the worst thing that could happen for the 7600.
anyways, the platform is not even well documented on cisco.com so it
can not be included in our business case. i expect a management
decision ASAP as our links are pretty congested on single failures as
we speak.

regards,
manu

>>
>> - Brocade/ Foundry NetIron XMR 16000
>> --- max 64 x 10GE
>> --- max 32 links in a bundle
>> --- 50Gbps per slot

>>
>> 4. is the netiron really a carrier router more than a carrier switch?
>> anybody experienced it?
>>
>> 5. how does the software perform when comparing with IOS XR and JunOS?

>> Please, any comments are welcomed.
