AIM-VPN/High Performance PLUS (HP II-PLUS) combines DES/3DES/AES (optimized for AES128, AES192, AES256) and Layer 3 (IPPCP) compression for Cisco 3660 and Cisco 3745. This advanced interface module (AIM) VPN Module can be added to current Cisco 3745, and Cisco 3660 platforms. This Module also offers DES/3DES and new AES from National Institute for Standards (Advanced Encryption standard). This VPN module is optimized for all AES key sizes (AES128, AES192, and AES256). In addition these VPN Modules support hardware-assisted Layer 3 (IPPCP) compression services where bandwidth conservation may lower network connection costs. This model can provide hardware-based encryption services up to 180-Mbps 3DES/AES(128, 192, 256) performance in the Cisco 3745 (max based on 1400 byte packet size).
