Viprion Balde 4450 Actual Throughput

Hi

I am checking the datasheet of Various bales of Viprion and Based on that Blade model 4450 provides 140Gbps throughput(L4/L7)

I have some questions here:

1) Is this value full duplex? I mean is it 140Gbps in Send direction and 140Gbps in Receive direction. or it is 70Gbps send and 70Gbps receive?

3) This blade has 100GE ports can I use them to get to this throughout?

2) Is this value is applicable for having the device working in CGNAT mode plus dynamic routing with BGP?

If the value is in half duplex then the total capacity of Viprion 4800 will be 560Gbps and because I want to pass about 800Gbps over the box then I must consider using two boxes with DSC and Load-Balancing....Right?

Thank you
