from inet to lan or inet

packet flow through openvpn server

alt cpu

1.system with modulator and demod unit
2.cpu has mod/demod
2.memory has mod/demod
3.cpu initiates a freq modulated with address,instruction,operand
4.memory gets selected
4.memory modulates operand and sends it in modulated freq
5.cpu demod operand,does operation with operand
6.cpu sends result to memory in modulated form

advantages of this system
1.operands can be fetched from multiple memories

disadv
1.this is not core design change

1.recursive bits,bytes,ram
2.each unit is addressable and operand
