The Cisco 4000 family Integrated Services Router (ISR) revolutionizes WAN communications in the enterprise branch. With new levels of built-in intelligent network capabilities and convergence, it specifically addresses the growing need for application-aware networking in distributed enterprise sites. These locations tend to have lean IT resources but often 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. The router provides routing, hosting, security, and switching—all in a single, trustworthy platform. It delivers 100 Mbps to 300 Mbps aggregate throughput and offers one Enhanced service-module (SM-X) slot, which supports for both single- and double-wide service modules, providing flexibility in deployment options. It also supports Cisco® Software Defined WAN (SDWAN) software features and a converged branch infrastructure, providing threat protection
