Cisco 4221 Integrated Services router is designed to deliver advanced services to the small enterprise branch environment. It delivers 35Mbps thoughtput by default. By buying licenses, the forwarding capacity can be increased to 75Mbps.
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.
