Cisco ISR 4451 Performance

[RS19]

In the data sheet of Cisco ISR 4451 for SD-WAN device I found the below.

Encryption throughput (Internet MIX)   400 Mbps

What does this mean ? 

Is encryption throughput means IPSec encryption ?

What does Internet MIX means ?

Any help or inputs ?

Hi, 

IMIX is a type of traffic used to test the performance of a device. 7:4:1 distribution of packets of sizes 64, 570, and 1518 bytes is commonly used.

So, the data would say that ISR4451 is capable of sending 400Mbps of encrypted(IPSEC) IMIX traffic.

Hope this helps.

Thanks!

Thanks. I got it.

Actually it is 2 Gbps for ISR4451 not 400 Mbps.

Understood your point. 

1 more clarification. I understand that it supports 2 Gbps of encrypted traffic . If there are unencrypted traffic like direct Internet Access will the throughput will be calculated separately or is it part of 2Gbps capacity?

Yes, DIA traffic will be calculated separately.
