Hi,
That is, I want to create a TUN device in SGW and allocate an IP address of the same system as the UE.
If so, can I create a tun device in sgw from the "no-backhaul-epc-helper.cc" file and modify the "epc-sgw-application.cc/h" file by referring to the "epc-pgw-application.cc" file? (Adding functions such as SendToTunDevice, for example.)
As mentioned above, I wonder if there is a problem with adding a tun device to SGW. If there's any reason why it's not implemented academically or realistically, please tell me.
Best Regards,
In lte, a Tun device is created in pgw, but why isn't a Tun device created in sgw?
Because of the TUN device, pgw seems to have the same ip address system (7.0.0.x) as ue, but I want to do the same thing to sgw.
