TE is really a buzzword used by vendor marketroids to extract cash from operators who could just as easily spend it on the competition's gear. IOW, the traffic that is engineered is the flow of money. 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? Cynically, Sean.

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.

Once, I asked an expert in telephone technology on the meaning of TE. Considering that telephone industry is working mostly on L2, there is no room to put Cisco-style TE. His answer was that TE in telephone industry means to just provide enough bandwdith. Masataka Ohta
