Cisco's new Tag Switching technology is a key component in Cisco's plans for meetign this challenge. Leveraging the strengths of Cisco and StraaCom, tag switching combines the performance and traffic management capabilities of Layer 2 (data link layer) switching with the proven scaability of Layer 3 (network layer) routing. Tag switching is the first technology to fully integrate routing and switching for an Internet-scale environment, and is one of several multilayer switching technologies being pioneered by Cisco.
