Software defined networking (SDN) is a centralized approach to networking that utilizes application programming interfaces (APIs) and software-based controllers to interface with underlying network infrastructure and manage network traffic.

This software-based network management model differs from traditional models. Legacy models utilize hardware devices such as switches and routers to manage network traffic. Software defined networks can manage traditional hardware or a virtual network via software. They enable the rapid programming, management, and provisioning of networks.

In this guide, we explore leading SDN providers that are helping to shape this new and growing market. Clearly, software defined networking trends are changing with remarkable speed as this emerging sector finds adoption.

What are the Benefits of SDN?

SDN is an architecture designed to make a network easier and more flexible to manage. The benefits of SDN include their ability to: 

  • Minimize complexity by decoupling the data and control planes, while making automation highly scalable and secure.
  • Leverage open APIs to deploy services and applications quickly.
  • Eradicate manual configuration, and manage and provision wide-area networks (WANs), campuses, and data centers.
  • Centralize cloud automation, service delivery, monitoring, control, management, and configuration.

Choosing an SDN Provider

SDN technology allows organizations to quickly and efficiently reconfigure and manage network resource usage by utilizing policy-based management and automated provisioning. Before selecting an SDN vendor, considerable homework is required – this is a highly complex product area and it’s very difficult to stay current with how quickly the technology is changing. 

Visit SDN vendors’ respective websites, go through product catalogs, compare features and pricing plans, and scrutinize peer-to-peer reviews. Perhaps most important in understanding which SDN solution best meets your organizational needs, speak with each sales rep at length. Get a sense of: 

  • Does this SDN solution interoperate with your current legacy network? Or will it be a full replace?
  • What is the vendor’s product road map? Are they expected to keep pace with change in the SDN market?
  • What is the vendor’s strategy in relation to the cloud? After all, some or many of the various software elements you’ll be using will be cloud-based.
