As mentioned last time, SDN theorists declare that SDN is the networking technology that separates the forwarding plane from the control plane. Of course the logical separation of networking into planes has been conventional for three decades, and time-honored tradition distinguishes three planes – those of forwarding, control, and management.

The concept of logical separation of a network’s operation into planes first surfaced during discussions in the ITU on ISDN in the 1980s. After initial proposals favored two planes, it was concluded that three planes were necessary, namely the forwarding plane, the control plane, and the management plane.

In the last year or so, SD-WAN has caught the attention of service providers, with some of them going as far as investing in related startups. At the same time, service providers began to realize that while the technology provides easy-to-deploy solutions that include VNFs, white boxes and a management suite, these solutions are in effect walled gardens.

5G is coming fast, promising to change – yet again – the way we connect to the world and consume data. It will enable ubiquitous wireless broadband, also known as enhanced mobile broadband (eMBB), (e.g., wireless-to-the-premises and broadband on high-speed trains, at events and in crowds) and other, entirely new market segments.

Network operators of power, water and gas utilities, transportation, safe cities and other critical infrastructure (CI) have their work cut out for them. Their operational technology (OT) networks are currently migrating from TDM to packet-based WANs – Carrier Ethernet, IP/MPLS and MPLS-TP – and they must make sure that they are able to maintain service and network reliability.

When NFV and SDN were first introduced, they held the promise of a true revolution – nimble networks, automated service rollouts and general purpose, low-cost white boxes replacing dedicated appliances – straight out of IT operations.
