Top software-defined networking solutions

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

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

In this guide, we examine leading SDN providers that are helping to shape this new and growing market. Obviously, software-defined networking trends are changing at a remarkable rate as this burgeoning sector gains acceptance.

What are the benefits of SDN?

SDN is an architecture designed to make managing a network easier and more flexible. SDN benefits include:

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