Sam Tenorio Provides an Overview of How SDN Connects Multiple Sites to its Data
Networks today are fundamental to the success of most organizations, allowing them to transmit data accurately and efficiently. As a valuable digital resource, many businesses have implemented SDN models in an effort to increase productivity and enhance daily operations.

As the Founder and CEO of Seamless Advanced Solutions (“SAS”), Sam Tenorio III knows how important software-defined networking (“SDN”) is in enabling the management of complex systems less complex. As an expert in the field, he is here to outline everything you need to know about SDN.

Understanding SDN

Networking technology has undergone a transformation over the past decade and many software-defined networks (SDN) were developed in response to the challenges associated with fragmented network architecture. The SDN origin can be traced back to a research collaboration between Stanford University and the University of California at Berkeley, yielding the OpenFlow protocol in 2008 which enables a dynamic, programmable, efficient network configuration. Since its original inception, SDN has evolved into a reliable networking technology offered by industry leading vendors such as Cisco, VMare, Juniper, Pluribus and Big Switch.

Unlike traditional networks, which are heavily dependent on hardware to manage physical connections, SDN separates the network control plane allowing network control to be centrally managed. Sam Tenorio explains that “one of the key elements in SDN is the concept of separating the control plane from the data plane. Separating these two elements is important because it enables network functions to be automated, making the architecture of SDN programmable, centrally controllable, and agile”.

The Benefits of SDN

An SDN provides a wide range of cost-related savings, including the reduction in hours spent on manual tasks. Sam Tenorio explains that “company’s now have the option of improved connectivity and enhanced internal communication. Ultimately, an SDN allows businesses access to software and hardware from multiple vendors resulting in a customized network services and infrastructure”.

Enhanced Security

SDN also enables a variety of security benefits. For example, a customer can split up a network connection between an end user and the data center and have different security settings for the various types of network traffic. It also allows businesses to selectively block malicious traffic while still allowing normal traffic flow. It can also make it easier to collect network usage information, which can support improved algorithms designed to detect network attacks.

The Bottom Line

SDN enables companies to automate processes that previously required an IT staff member to manually execute those processes. Automation is faster, more reliable, and cost effective. Moving forward, Sam Tenorio explains that there are multiple developments to watch for.



“One is the ability to automate the provisioning of data center services, making it easier to horizontally extend access to data.



Second is the ability to more easily allow customers to work across multiple domains to monitor and track what is going on across the infrastructure. Unsurprisingly, according to a recent IDC study, a premier global market intelligence firm, the worldwide data center SDN market will be worth more than $12 billion by 2022”.
