Cisco ISR 4451x vs ASR 1002

[orxan20]

Hello Everyone.

I have 50.000 devices on my site. all this computers access 3 ip address and 1 port every second (without stopping)

which router do you advice? 

which router can handle this amount of connection?

now i have 4451x but there is some problems ( i configured nat pool with 4 global ip addresses) it is about 260.000 translation but when it hits 100.000 translation router can not handle new translation and we loose internet connection for other users.

I would suggest to contact Local SE or Cisco partner to asses what is the this usage ? and give right solution.

if you looking community answer, personally i choose ASR they are higher level routers - regarding performance you need to Look what kind of features required ? NAT ,. SEC, and more ?
