What Else? Prepare your branch site and protect it for the future with the Cisco 4000 Series ISR digital-ready platform now.

The Cisco ISR 4000 Series routers consolidate many must-have IT functions, including network, security, compute, storage, and unified communications. So you get everything you need in a single platform. The platform is modular and upgradable, so you can add new services without changing equipment. It supports multiple application-aware services concurrently while maintaining WAN performance of up to 2 Gbps, even during heavy traffic loads.

The backplane architecture supports high-bandwidth, module-to-module communication at speeds up to 10 Gbps.

██ Highlights
  • Cisco IOS Universal Image (IP Base/SEC/UC/AX)
  • High-performance multicore processors for high-speed WAN connections and multiple services
  • Separates control- and data-plane operations (Cisco 4431/4451: the default control-plane memory is 4 GB, upgradable to 16 GB, and the default data-plane memory is 2 GB)
  • Cisco Enhanced Services Module (SM-X) and Cisco Network Interface Module (NIM) integrate networking, services, computing, and storage into a single form factor
