ISR4221/K9 - Cisco ISR 4221 Router

• Cisco Intelligent WAN (IWAN)
  Cisco IWAN is a set of intelligent software services that allow you to reliably and securely connect users. devices. and branch office locations across a diverse set of WAN transport links. IWAN-enabled routers like the 4000 series dynamically route traffic across the 'best' link based on up-to-the-minute application and network conditions for great application experiences. You get tight control over application performance. bandwidth usage. data privacy. and availability of your WAN links - control that you need as your branches conduct greater volumes of mission-critical business.
• Cisco converged branch infrastructure
  The Cisco 4000 series ISRs consolidate many must-have IT functions. including network. compute. and storage resources. The high-performance. integrated routers run multiple concurrent IWAN services. including encryption. traffic management. and WAN optimization. without slowing your data throughput. And you can activate new services on demand through a simple licensing change.

The Cisco 4000 series Integrated Services Routers (ISR) revolutionize WAN communications in the enterprise branch. With new levels of built-in intelligent network capabilities and convergence. the routers specifically address the growing need for application-aware networking in distributed enterprise sites. These locations tend to have lean IT resources. But they often also have a growing need for direct communication with both private data centers and public clouds across diverse links. including Multiprotocol Label Switching (MPLS) VPNs and the Internet.
