The Cisco® VPN Services Adapter (VSA) for Cisco 7200 Series routers provides high-performance encryption and key-generation services for IP Security (IPsec) VPN applications. With the Cisco VSA, customers can use their existing Cisco 7200 routing infrastructures for cost-effective deployment-and can do so while obtaining the highest IPsec performance available in this class of routers, providing secure VPN connectivity along with multilayer LAN and WAN routing capabilities.
Cisco VSA greatly increases the performance over the existing VPN acceleration modules. Like the VAM2+, the VSA supports Data Encryption Standard (DES), Triple DES (3DES), and Advanced Encryption Standard (AES). It includes hardware acceleration for 128-, 192-, and 256-bit AES keys. The VSA requires the Cisco 7200 Series NPE-G2 Network Processing Engine and fits into the I/O controller slot on the Cisco 7204VXR or 7206VXR chassis, conserving valuable bandwidth points for other port adapters.
This combination of security features and high performance offers a flexible, integrated approach to accommodate the most diverse enterprise or service provider network environments, while providing investment protection for existing Cisco 7200 Series router customers.
