Cisco 2900, 3900, and 4000 (4300 and 4400) Series Integrated Services Routers can communicate directly with Cisco Unified Communications Manager, allowing for the deployment of unified communications solutions that are ideal for small and medium-sized businesses, large enterprises, and service providers that offer managed network services.
In addition to everything integrated from previous generations, the ISR 4000 Series introduces several new concepts to branch routing. Separate CPU complexes for control plane and packet processing is nothing new, but the ISR 4K brings this technology down into the Enterprise branch for the first time in an affordable way that looks and feels as familiar as the traditional ISRs. Virtualization of services is a popular solution and the ISR 4K includes both server virtualization as well as a built-in hypervisor for integrating network-focused virtual machines right on the router itself through Service Containers. Add in license-based performance and you have a platform designed to grow with you through additional services and performance without the need to replace hardware in the field or over-buy more capability than you need up front.
ISR 4000 Series address management with support for both traditional network management platforms and models as well as emerging standards. That means they include support for the same IOS CLI, SNMP, and management protocols that have been around for 20 years as well as newer concepts such as REST, SDN, and programmability through Cisco onePK.
