Critical high-bandwidth business applications have created a need for ubiquitous connectivity and increased bandwidth. Shared campuses, metro area networks and Internet data centers require high performance and secure connectivity. Many enterprises augment or replace their traditional WANs with site-to-site and remote-access virtual private networks (VPNs) to better accommodate these new connectivity requirements. The Cisco IPSec VPN Services Module (VPNSM) delivers cost-effective VPN performance for the Cisco Catalyst 6500 Series switches.
