Why did Cisco invent Tag Switching? Hint: where is Ipsilon these days? Hint II: how many big-iron ATM vendors are at the core of the Internet today?
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 wireless). 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. Pete.
