What is Cisco NSO?
Cisco Network Services Orchestrator (NSO), or Cisco NSO, is a network automation platform that offers a number of robust features for service providers and large enterprise environments. NSO excels in managing complex, multi-vendor networks and is particularly well-suited for scenarios involving:
- Service orchestration: NSO enables service providers to design, deliver, and manage network services with the necessary flexibility. These include automating services such as provisioning, configuration, and, most importantly, lifecycle management.
- Network virtualization: NSO helps in the process of creating, building, and managing VNFs to allow network operators to efficiently deploy and expand the range of services.
- Multi-vendor environments: NSO shines in environments where various vendor equipment needs to be managed under a unified platform. It provides a single point of control for configuring, monitoring, and troubleshooting diverse network devices.
- Policy-driven automation: NSO enables the development of policies that regulate usage of the network and sorts it in a way that can scale up and down according to the changes within the network or services needed by the end customer. This helps to maintain compliance and make the network configurations more consistent across the network.
In simple words, NSO is built for service orchestration. It is strong when you need to coordinate changes across many devices and services.
Key Use Cases
Here are some key use cases of Cisco NSO:
- Simplification of Service configuration across multiple network devices and vendors.
- Integration with SDN Controllers and other network automation tools.
Where Cisco NSO fits best?
Cisco’s own NSO documentation gives very practical use cases.
It highlights things like:
- device turn-up
- NFV orchestration
- SD-WAN orchestration
- ACL management
- QoS management
- config audits
- OS upgrades.
These examples show that NSO is useful when you need:
- repeatable service logic
- orchestration across many devices
- lifecycle control
- and multi-vendor automation
That is why NSO often appears in provider, hybrid, or larger orchestration-heavy environments.
Why choose Cisco NSO?
Cisco NSO provides a highly scalable and flexible platform to organizations that operate complex, multi-vendor networks, and need a solution to automate service provisioning and orchestration.
What is Cisco Catalyst Center?
Cisco Catalyst Center, formerly known as Cisco DNA Center, is a network management application that is specially designed for enterprises that want to streamline their network and receive more detailed insights into their infrastructure. It aims to provide a centralized control point for managing all aspects of the network, including:
- Network discovery and inventory: Upon deployment, the Catalyst Center is capable of discovering and cataloguing network devices that are connected to the network and provides essential data about the configurations and connectivity status of connected devices.
- Policy-based network management: Catalyst Center enables administrators to set up network guidelines and policies and enforce them throughout the network. This ensures consistency in configurations, access privilege, and security settings at each instance it is provisioned to.
- Network assurance and troubleshooting: Catalyst Center provides vital network visibility and monitoring resources, allowing the network teams to investigate and solve issues.
- Wireless management: The wireless network management solution offered by Catalyst Center includes access point management, client management on wireless networks, and security.
In simple words, Cisco Catalyst Center is built for enterprise network operations and assurance.
Note: Catalyst Center has been mainly marketed to enterprises as it addresses the issues of simplifying networks, maintaining security, and improving the performance of the network. It comes with a user-friendly graphical user interface that can be easily accessible to network administrators with varying skills.
Use cases of Catalyst Center
