In the annals of networking history, there are giants – the dinosaurs of connectivity that once ruled the landscape. Back in 2009, I had the privilege of pioneering separate VLANs on private Layer 2 WAN circuits in South Africa, a groundbreaking move at the time. Fast forward nearly 15 years, and the networking realm has evolved, leaving MPLS, IPSEC, and private Layer 2 WAN circuits resembling dinosaurs in the age of SD-WAN.

The Era of VLANs on Private Layer 2 WAN Circuits

In the late 2000s, the demand for private Layer 2 WAN circuits surged, driven by the need for secure and dedicated connections. I remember those days vividly, working for WBS as we provisioned 3500 circuits with separate VLANs. It was revolutionary, especially for voice circuits that suffered when shared with bandwidth-hungry applications like illegal movie downloads. VLANs provided the solution, ensuring that voice circuits remained pristine amidst the chaos.

When dinosaurs ruled the Earth

Cast your mind back to the networking landscape of the late 2000s. It was a time when MPLS, IPSEC, and private Layer 2 WAN circuits ruled the networking jungle. As we reminisce about these once-mighty technologies, let's take a trip down memory lane and explore why they were considered the dinosaurs of their time.

The Rise of MPLS

Multiprotocol Label Switching (MPLS) was the undisputed king of enterprise networking. Praised for its reliability and deterministic traffic routing, MPLS provided businesses with a dedicated and secure pathway for their data. It was the go-to solution for organizations seeking to connect multiple locations seamlessly.

IPSEC: The Security Sentinel

IP Security (IPSEC) held the fort as the guardian of data integrity and confidentiality. Tunneling protocols like IPSEC created secure connections over public networks, ensuring that sensitive information remained shielded from prying eyes. It was a crucial component in the arsenal of any organization prioritizing data security.

Layer 2 WAN Circuits: Bridging the Gaps

Private Layer 2 WAN circuits, like the ones implemented back in 2009, were considered groundbreaking. I, myself, as mentioned above was part of the team that introduced separate VLANs on private Layer 2 WAN circuits in South Africa while working for WBS. This innovation allowed for efficient communication between geographically dispersed offices, fostering collaboration and data sharing.

The Evolving Landscape

Fast forward to today, and the networking ecosystem has undergone a seismic shift. The dinosaurs of yesteryear, once heralded as the pinnacle of connectivity, now face extinction in the wake of newer, more agile technologies.

  1. MPLS: A Relic of the Past? MPLS, while reliable, comes with a hefty price tag and lacks the flexibility demanded by modern, dynamic business environments. The rise of SD-WAN has challenged the dominance of MPLS by offering a more cost-effective and adaptable solution.

  2. IPSEC: Encryption in the Age of SDP With the advent of Software-Defined Perimeters (SDP), the traditional reliance on IPSEC for secure connections is waning. SDP provides a more granular and dynamic approach to network security, limiting exposure and reducing attack surfaces.

  3. Layer 2 WAN Circuits: Bridging Beyond VLANs While Layer 2 WAN circuits facilitated connectivity, the approach had its limitations. Today, organizations are turning to SD-WAN solutions that transcend the constraints of traditional Layer 2 approaches, offering improved scalability, efficiency, and security.

The Challenge of Dinosaurs

As effective as VLANs were in their time, the networking landscape has undergone a seismic shift. MPLS, IPSEC, and private Layer 2 WAN circuits, once the stalwarts of connectivity, are now facing obsolescence in the face of a more dynamic, agile, and intelligent solution – SD-WAN.

  1. SD-WAN: A Quantum Leap Forward: SD-WAN represents a quantum leap in networking technology. Unlike its predecessors, SD-WAN leverages intelligent routing algorithms, application-aware traffic management, and centralized control, eliminating the need for separate VLANs and mitigating conflicts in real-time.

  2. Dynamic Traffic Steering: The dinosaurs struggled with dynamic traffic steering, often resulting in performance issues during peak usage. SD-WAN's dynamic path selection ensures optimal routing based on real-time network conditions, providing consistent and reliable connectivity.

  3. Application Visibility and Prioritization: In the era of dinosaurs, visibility into application performance was limited. SD-WAN, however, provides granular insights into application behavior, allowing for the prioritization of critical traffic and ensuring a seamless user experience.

  4. Cost-Effective and Agile: Dinosaurs like MPLS came with hefty price tags and long deployment cycles. SD-WAN offers cost-effective solutions with quick deployment, enabling businesses to adapt rapidly to changing network requirements.

  5. End of Circuit Saturation Woes: The separate VLANs that once saved voice circuits from saturation are now replaced by SD-WAN's dynamic bandwidth allocation and Quality of Service (QoS) features, ensuring each application gets the bandwidth it needs.

Embracing the Future

As we bid farewell to the dinosaurs of networking, it's crucial to embrace the future – the era of SD-WAN. It's time to evolve beyond the limitations of MPLS, IPSEC, and private Layer 2 WAN circuits and harness the power of intelligent, software-driven networking. The once-revolutionary solutions, like separate VLANs, have paved the way for a more sophisticated and adaptable approach. Let the dinosaurs retire, and let SD-WAN lead us into the next era of networking evolution.
