Software Defined Networking:
The uture of Secure, Efficient, Connectivity

Software Defined Networking or SD networking is expected to grow at warp speed in the next couple of years, and here’s why.

Today’s current enterprise networks are becoming convoluted as many businesses continue building out their connectivity using legacy technologies (i.e., Multi-Protocol Label Switching (MPLS)), requiring additional hardware at each location to maintain network efficiency.

Cloud and Managed Services have altered traffic flows within distributed organizations. Remote users require significantly more bandwidth (e.g., when using video), but they also need to directly access Software-as-a-service (SaaS) / cloud-based applications such as Salesforce, Microsoft 365, Lync and off‐premise storage (such as Dropbox, Evernote, and so on).

Because many of today’s applications are moving out of the corporate data center and into third-party cloud and Software as a Service (SaaS) environments, traffic flows within the network have drastically changed and become inefficient for application delivery.

We’ve talked about OTELCO SiteLink and VoiceLink which provide the security and control of a Local Area Network (LAN) over a Wide Area Network (WAN) addressing many of these security and efficiency issues.

Some background information for those of you who might not be familiar with these products.  Both SiteLink and VoiceLink require an on-net Layer 2 circuit from a customer location back to our network where we consolidate them onto a cloud hosted WAN. SiteLink provides end users with a private multi-site L2 network and VoiceLink is similar except it is intended to provide a WAN and DHCP (i.e., Dynamic Host Configuration Protocol or a network protocol that enables a server to automatically assign an IP address to a computer from a defined range of numbers configured for a given network) services exclusively for HPBX IP phones isolating them from other networks to simplify and streamline deployment and also bypass customer router and firewall issues.

If OTELCO is your Internet provider, all of this is awesome; if not, then what?

SiteLink SD and VoiceLink SD

Our new SD products employ software defined networking and are designed to streamline connectivity between multiple sites while increasing security and allowing for central control of multiple sites.  SiteLink SD and VoiceLink SD will work with of ANY Internet connection and then automatically establish an IPSec tunnel back to our core. This “VPN-like” tunnel creates a secure and reliable alternative for us to extend SiteLink or VoiceLink to locations where an on-net OTELCO circuit is not available.

According to Gartner, by 2020, more than 50% of WAN edge infrastructure will be based on software defined networking technology; today it’s less than 5%.  One reason for such a generous projection is the fact that truly cutting edge technology is typically cost prohibitive when first released, in the case of SD technology you can actually save money in a few ways:

  • Reduce costs associated with hardware
  • Free up IT staff for business development tasks
  • Reduce deployment time when adding new locations

At OTELCO, the future is now: SiteLink SD and VoiceLink SD are available October 1st!
