Family Integrated Services Routers (ISRs) form an Software Defined WAN platform
that delivers the performance, security, and convergence capabilities that
today’s branch offices need.
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 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 Cisco 4000 Family contains the following platforms: the 4461, 4451, 4431,
4351, 4331, 4321 and 4221 ISRs.
Cisco 4000 Series Integrated Services Routers
Features and Benefits
Cisco 4000 Family ISRs provide you with Cisco® Software
Defined WAN (SDWAN) software features and a converged branch infrastructure.
Along with superior throughput, these capabilities form the building blocks of
next-generation branch-office WAN solutions.
Cisco Software Defined WAN
Cisco SDWAN 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. SDWAN-enabled routers like the ISR 4000
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 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.
Cisco Intent Based Networking and Digital Network Architecture (Cisco DNA)
The last few years has seen a rapid transformation and adoption of digital
technologies. This puts pressure on the on the Network teams supporting this
changing infrastructure - especially when provisioning, managing, monitoring and
troubleshooting these diverse devices. Additionally innovations such as Software
Defined WAN (SDWAN), Network Function Virtualization (NFV), Open APIs and Cloud
Management show great promise in transforming Organizations IT networks. This
transformation raises further questions and challenges for the IT teams.
The Cisco Digital Network Architecture (Cisco DNA) is an open, extensible,
software-driven architecture that provides for faster innovation, helping to
generate deeper insights, and deliver exceptional experiences across many
different applications. Cisco DNA relies on intent-based networking, a
revolutionary approach in networking that helps organizations automate,
simplify, and secure the network.
The intent-based Cisco DNA network is:
● Informed by Context: Interprets every byte of data that
flows across it, resulting in better security, more customized experiences, and
● Powered by Intent: Translates your intent into the right
network configuration, making it possible to manage and provision multiple
devices and things in minutes.
● Driven by Intuition: Continually learns from the massive
amounts of data flowing through it and turns that data into actionable insight.
Helps you solve issues before they become problems and learn from every
Cisco DNA Center provides a centralized management dashboard across your entire
network — the branch, campus, data center, and cloud. Rather than relying on
box-by-box management, you can design, provision, and set policy end-to-end from
the single Cisco DNA Center interface. This allows you to respond to
organizational needs faster and to simplify day-to-day operations. Cisco DNA
Analytics and Assurance and Cisco Network Data Platform (NDP) help you get the
most from your network by continuously collecting and putting insights into
action. Cisco DNA is open, extensible, and programmable at every layer. It
integrates Cisco and third-party technology, open APIs, and a developer
platform, to support a rich ecosystem of network-enabled applications.
