Maybe I am misunderstanding something, but I really don't see what is the reason behind handling the echo requests in the GGSN instead of the gtp-u stack itself. Can someone please shed some light on this one?
because when you send an ECHO request, you want to know if the full GTP stack on the other side is still alive, both for control and for user plane? If you automatically replied to them from the kernel, it mihgt be that just the user plane (kernel space) is still alive, while the control plane (user space) is already dead?
