Critical business applications are driving the need for ubiquitous connectivity and increased bandwidth to remote locations. Many enterprises are augmenting or replacing their traditional WANs with site-to-site virtual private networks (VPNs) to better accommodate these new connectivity requirements.The Cisco 7400 Series Router VPN performance is suitable for large branch and head-end locations. Using the VPN Acceleration Module (VAM) hardware encryption acceleration card, the Cisco 7400 Series can support up to 5000 simultaneous IP Security (IPSec) tunneling sessions with Triple Digital Encryption Standard (3DES) IPSec encryption performance up to 120 Mbps, enabling scalable VPN connectivity to remote offices and extranet partners. In addition, the VAM provides hardware-assisted compression services for bandwidth conservation, thus reducing network connection costs. The Cisco 7400 Series is ready to deploy out of the box with default VPN configuration and pre-loaded with the Web browser-based Cisco VPN Device Manager (VDM) management software. All interfaces, software, and hardware required for scalable, turnkey VPN deployment are included in the base model. The Cisco 7400 Series utilizes Cisco IOS Software features to accommodate multicast and multiprotocol traffic, as well as routing and quality of service (QoS) across the VPN, thus delivering flexible solutions for the most diverse VPN environments. The rich routing functionality inherent to the Cisco 7400 Series also simplifies VPN deployment by eliminating burdensome static routes associated with VPN appliances.This Cisco 7400 VPN Router features dual embedded 10/100/1000 Gigabit Ethernet interfaces, VPN Acceleration Module, 128 MB system memory, 64 MB Flash memory, single AC power supply, Cisco IOS Software with IPSec 3DES (168-bit).
