Overview

The Cisco 4451-X Integrated Services Router revolutionizes the delivery of application aware services in a branch-office environment. This platform extends the Cisco ISR Family by providing Gigabit performance with extensive Layer 7 services hosted internally to the branch office while maximizing operating expenses (OpEx) savings.

The Cisco 4451-X offers a multicore CPU architecture running modular Cisco IOS XE software that quickly adapts to the changing needs of your branch-office environment, and enables IT to roll out services at the speed of business. The separation of the control and data planes provides the ability to deliver application-aware network services while maintaining a stable platform and a high level of performance during periods of heavy network load. With the ability to integrate application-aware services and the ability to scale performance without a complete equipment upgrade, the Cisco 4451-X offers exceptional total cost of ownership (TCO) savings and network agility through the intelligent integration of market-leading security, unified communications, and application services.

The Cisco 4451-X offers encryption acceleration, voice- and video-capable architecture, application firewall, call processing, and embedded services. In addition, the platform supports a range of wired connectivity options such as T1/E1, T3/E3, and fiber Gigabit Ethernet. This platform offers superior performance and flexibility for network deployments across large and medium-sized enterprise offices.
