Why you need Internet Protocol everywhere

  • IP frees all sites and end users to use a common suite of IP services.

  • You also need IP everywhere to reach Software-Defined Networking (SDN)

  • Older links are eventually going to be turned off in favor of IP.

You should be running Internet Protocol (IP) across your entire network. Not just in your core Wide Area Network (WAN) and your primary sites. Everywhere.

Before you tell me, “Everybody knows that,” consider this: Just because you’re running IP across your Multi-Protocol Label Switching (MPLS) or Internet Protocol Security (IPsec) WAN backbone doesn’t mean there aren’t some analog or Time Division Multiplexing (TDM) services lurking around. Conduct an audit of your entire services inventory to find out. Your network might have grown so big and complex that it’s harboring antique services that disappeared off your radar long ago.

Why it pays to run IP across your entire network

Analog, TDM (T1/T3), and even frame relay services won’t sustain you through the future. So create a plan to replace them with IP. Here are other reasons that you need IP everywhere.

  • A common suite of IP services. 

As the de facto common denominator in intelligent networking, IP frees all sites and end users, stationary or mobile, to use a common suite of IP services. Consistent functions everywhere mean happy, productive, “no-excuses” users.

  • Software-defined networking (SDN).

You also need IP everywhere to reach that networking nirvana we call SDN. IP paves the way for SDN’s promised top-down programmability, automated and dynamic configuration, and user self-provisioning.

  • Older links are going to be turned off. 

Sites without IP WAN connections won’t reap the benefits above. That’s the strategic issue. Meanwhile, the older links are going to be turned off in favor of IP in about half a dozen years. That’s the practical issue.

So sniff around to locate any old circuit-switched or frame relay services. Begin migrating them to IP for optimal return on all your WAN connections. You’ll lay vital groundwork for SDN. And you’ll avert a crisis when your Supervisory Control and Data Acquisition (SCADA) or fractional T1 link goes dark one day.
