I am curious about the processing method in terms of hardware architecture.

I recently compared the H/W architecture of the PA-3200 series and the PA-3400 series and had a question.

Looking at the architecture below, it appears that N/W and Security Processing, which were previously separate, have been merged into one starting with the 3400 Series.

Does this mean parallel processing in DP?

Otherwise, is it just the display format that has changed?

Also, previously there was an offload engine in the DP, but starting from the 3400 Series, there is a crypto assist in that location.

And I think offload engine means 'create and install session' in slow_path of packet flow

If this is correct, does the 3400 series handle Session offload, which was previously handled by DP, in a different way?

Lastly, I'm curious about the role of the switch in the 3400 series.

According to what I found out, I confirmed that starting from the 3400 series, there is no H/W FPGA and there is something called switch fabric.

But I don't know what difference this makes in how the 3200 and 3400 behave
If anyone knows, I would really appreciate it if you could reply.

I have a lot of questions, but I'll wait for a good answer.

have a good day
