You can use the table in the figure to determine which enterprise model is best for your environment. The table identifies router platforms, and their related hardware encryption accelerator card and maximum throughput. Lab performance numbers are based on the following configuration: 3DES with HMAC-SHA-1, 100% CPU use, and no other services running, such as QoS, NAT, GRE, and so on. Actual network performance varies depending on the services running in each router.
Hardware encryption accelerator cards provide high-performance, hardware-assisted encryption, and key generation suitable for VPN applications. For the enterprise routers, there are three versions:
■ VPN Acceleration Module (VAM)—The VAM for Cisco 7200 and 7100 series routers provides high-performance, hardware-assisted encryption, and key generation. VAM also supports IP payload Lempel-Ziv Compression (LZS) compression services for VPN applications. There are two versions: VAM Service Adapter and VAM Service Module.
Integrated Service Module (ISM)—ISM uses a special slot created for offloading encryption and key generating services within the Cisco 7100 series routers (maximum of one ISM per Cisco 71XX series router).
Integrated Service Adapter (ISA)—ISA is a service adapter that inserts in any open port adapter slot in any Cisco 7200 router and can be used within the single port adapter of the Cisco 7140 router (up to one ISA per Cisco 7140 router or two per Cisco 7200 series routers, and not available on Cisco 7120 router).
The Cisco IPSec VPN Services Module is a high-speed module for the Cisco Catalyst 6500 Series Switch. Incorporating the latest in encryption hardware acceleration technology, the Cisco
IPSec VPN Services Module can deliver up to 1.9 Gbps of 3DES traffic and can terminate 8000 IPSec tunnels.
