What Is Hybrid Software-Defined-Network (Hybrid SDN)?

Greetings, members of the Hybrid SDN (Hybrid Software-Defined Network)! Are you ready to find out about a significant breakthrough in the field of networking? Hybrid SDN? You got it! Sure, some of you probably wonder, "Wait a minute—excuse me, but what is a Hybrid Software-Defined-Network?" We've got you covered, so don't worry. Let's start by explaining some specialized vocabulary. A software-defined network (SDN) is an architecture in which the control and data planes operate independently. Put another way, a central controller handles everything, rather than individual network devices (such as switches and routers) regulating data traffic. However, a hybrid SDN expands upon this concept in novel ways. The controller in a hybrid SDN manages the data plane and other traditionally "non-software-defined" portions of the network. It could manage firewalls and load balancers, for instance. This is where we introduce the hybrid aspect. You can think of it as a hybrid of software-defined and more conventional networking. Imagine a cyborg that possesses some of the traits of a human. A hybrid SDN incorporates software-defined and traditional elements, much like a cyborg. Now, let's examine the benefits of utilizing a hybrid SDN. There are a few explanations. One benefit is the simplification of administrative tasks related to your network. The need to administer several devices independently is eliminated in favor of a centralized controller. This helps you save much work. Increased adaptability is also another benefit of a hybrid SDN. Adding new devices to your network and modifying data flows is simplified. This information is helpful when coping with variable traffic conditions or other issues. Some may wonder, "That's awesome in theory, but what are the steps to implementing a hybrid SDN in practice?" This is not child's play, but it is not highly complicated. You'll need to be well-versed in networking principles and protocols, and you'll have to carefully select the hardware and software that will power your network. OpenFlow (a protocol used to communicate between the controller and network devices), SDN controllers (such as the OpenDaylight or Ryu controllers), and network virtualization are some of the technical terms you'll want to keep in mind when setting up a hybrid SDN (which lets you create virtual networks that the SDN controller can control). Well, Hybrid SDN users, you have your answer there. My goal in this article was to provide a high-level explanation of a hybrid SDN and how it could benefit your network.
