How do you go about programming a GGSN?
Originally I thought you could get a PC running linux and run a GTP
interface on it. However all carrier grade stuff uses hardware routing
(understandable if you want to cater for millions of customers).
For instance it seems that the GGSN is programmed on top of e.g. a
Cisco 7600 router, or a Juniper M20.
I can't tell how this programming is done unless you have access to the
router operating system (not available to the individual as far as i
can tell)
Is there another way of IP sessions and packets, with a decent
(scaleable) interface. Can I build some hardware with a good 'data
plane'
Obviously I can't afford 20k for a carrier grade router but I want to
write some software that could scale to such a device.
Thanks very much.
