Ipsilon must be the secret sauce in accelerating Nokia's
firewalls. Or someone had an awesome idea for MPLS-switched
cellular networks (that must be what happened to 2G

If Tag Switching was how everyone dumped their ATM, it's
been awfully quiet. Other than MPLS-VPN (to replace the IP
VPN headache with another one), doesn't seem like MPLS is
being adopted much at all right now.
