AIM-VPN/Base Performance PLUS (BPII-PLUS) combines DES/3DES/AES (optimized for AES128, AES192, AES256) and Layer 3 (IPPCP) compression for Cisco 2600XM. This new advanced interface module (AIM) VPN Module can be added to current Cisco 2600XM. This VPN Module offers DES/3DES and new AES (Advanced Encryption standard) from the National Institute for Standards. 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 module can provide hardware-based encryption services up to 20-Mbps 3DES/AES (128, 192, 256) performance in 2611 and up to 22 Mbps 3DES/AES(128, 192, 256) performance on the Cisco 2651XM (max based on 1400 byte packet size).
