Cisco's Software Control:

While researching Extreme (EXTR) for the Hunt, I came across this article:

zdnet.com

The interesting part was on Switched Routing:

Cisco's Tag Switching architecture is a good example of switched routing. To implement tag switching, Cisco routers are software-upgraded to become either tag-edge routers or tag switches depending on their location in the network. A tag-edge router is a true router that sits on the network edge and adds addressing information, in the form of fixed-length identifiers called tags, to packets entering the network. A tag switch is a router or switch that sits on the interior network and uses the tags to determine the appropriate path through the network for each packet. The use of tags reduces the complexity of packet decoding and table lookups when forwarding packets. Cisco has also created the Tag Distribution Protocol (TDP) to allow tag routers and switches to distribute tag information. Cisco has submitted tag switching to the Internet Engineering Task Force (IETF) for standardization.

Looks like Cisco is creating a new proprietary protocol. Is this an example of the Gorilla is defending its router dominance through software?

p.s. The article was a good primer of switches cracking into Layer 3 "routing".
