[c-nsp] Cisco equivalent of juniper hardware

[Phil Bedard]

The ES20 has most of the same feature set as the SIP-400, and if  
Ethernet is really
what you want, it's a cheaper option.   The ES20 w/better DFC is  
$60k.  The SIP-400
itself is $35k and then each 2-port GigE is $10k.  You can only put 4  
GigE ports in a
single SIP-400 before it may be oversubscribed.  Whether it's  
oversubscribed depends on
your packet size since it's PPS limited, not backplane bandwidth  
limited.

Worst case scenario you need 3 SIP-400s with 5 2xGE SPAs, which is  
$155,000.  Versus
20 line-rate GigE ports that costs $60k, or even with the IPV6/MPLS  
VPN license is
$100k...

The SIP/SPA GigE pricing is a lot, I think that's why they did the  
ES20 for those who
need more GigE with more features.
