Cisco VPN Acceleration Module 2+-Cryptographic accelerator-plug-in module

The Cisco VPN Acceleration Module 2+ (VAM2+) for Cisco 7200 Series and 7301 routers provides high-performance encryption/compression and key generation services for IP Security (IPSec) VPN applications. Like the VAM2, the VAM2+ supports both Data Encryption Standard (DES), Triple DES (3DES), and Advanced Encryption Standard (AES) 128-bit keys, but adds hardware-acceleration for 192 and 256-bit AES keys. The VAM2+ continues to integrate hardware-assisted Layer 3 compression services with its encryption services, conserving bandwidth and lowering network connection costs over secured links. This combination of security features and advanced network services offers a flexible, integrated approach to accommodate the most diverse enterprise or service provider network environments.
