LNS hardware and chassis recommendation

[Jerome Tissieres]

I'm looking at the most scalable alternative for an LNS for a small/mid-size ISP.

I have looked at Cisco 10K, ASR 1000, maybe a 7600 and it's difficult to compare the price/features/road-map.

Any recommendation?

Is there a Cisco white paper comparing the chassis for a LNS?

Thanks a lot,

Rgds.
