Networking Tech with Fexingo: Internet Infrastructure, Routing, and Network Engineering

In this episode of Networking Tech with Fexingo, Lucas and Luna dig into the Border Gateway Protocol — the glue that holds the internet together — and why it's struggling under the weight of modern complexity. They explore real-world cases like the 2021 Facebook outage and the 2017 Google route leak, breaking down how BGP's trust-based design creates vulnerabilities and how operators are fighting back with RPKI and BGPsec. They also look at how the rise of AI data centers and edge computing is pushing BGP to its limits, and whether new approaches like segment routing and centralized controllers could eventually replace it. If you've ever wondered why the internet sometimes breaks in weird ways, this episode gives you a clear-eyed look at the protocol that keeps it all running — and what might come next.

In this episode, Lucas and Luna explore the quiet revolution of network disaggregation — why operators are moving away from monolithic switches and routers toward open hardware and independent operating systems. They start with a concrete example: a cloud-scale operator that swapped a proprietary stack for white-box switches running open source software, cutting per-port cost by half. From there they dig into the practical math — what changes when you buy hardware from one vendor and software from another, how ONIE and NOS choices like SONiC and FRR change the upgrade path, and why some big incumbent vendors have started offering their own flavors of disaggregated gear rather than fighting it. They also talk about the catch: more choice means more integration work, and the skills gap that keeps many enterprises on the sidelines. If you've ever wondered whether the future of networking is less about black boxes and more about building blocks, this is the episode for you.

In this episode of Networking Tech with Fexingo, Lucas and Luna explore how network automation is fundamentally changing the way engineers interact with network devices. They trace the evolution from the command-line interface to modern automation frameworks, using real-world examples like the shift from manual router configuration to automated deployment at scale. The conversation highlights the rise of intent-based networking, the role of APIs, and the new skills required for network engineers in an automated world. They also touch on the challenges of legacy systems and the importance of human oversight. Tune in to understand why the CLI is becoming a thing of the past and what it means for the future of network engineering.

In this episode, Lucas and Luna dive into Segment Routing Policy, the technology that gives network operators a programmable, centralized way to steer traffic with a simple list of instructions embedded in the packet. They explain how it builds on the earlier Segment Routing MPLS episode, but with a fresh focus on the policy layer — the brain that decides which path a packet should take, and how it's enforced across large, distributed networks. They walk through a concrete example: how a large content provider uses Segment Routing Policy to balance load across multiple paths, avoiding congestion and improving resilience, without the complexity of RSVP-TE. They also touch on the role of a central controller, the trade-offs between stateful and stateless approaches, and how this is already showing up in real-world backbone and data-center networks. By the end, you'll have a clear mental model of how Segment Routing Policy works, why it's gaining traction over older traffic-engineering methods, and what it means for the future of network automation and SDN.

In this episode of Networking Tech with Fexingo, Lucas and Luna explore how segment routing is changing the way networks recover from failures. They dive into a real-world case: a major European ISP that deployed segment routing to cut failover times from seconds to milliseconds. The conversation covers the basics of segment routing, how it improves on traditional MPLS, and why it's becoming a key tool for network resilience. They also touch on the role of SRv6 and how operators are using it to simplify their networks. If you're curious about the future of internet infrastructure, this episode offers a clear, practical look at a technology that's quietly making the internet more robust.

In this episode of Networking Tech with Fexingo, Lucas and Luna dive into network slicing, the technology that lets carriers carve a single physical network into multiple virtual networks, each tuned for a specific use case. They explore how a mobile operator can guarantee low latency for autonomous vehicles while simultaneously delivering high bandwidth for video streaming, all over the same infrastructure. Lucas explains the role of SDN and NFV in making slicing possible, and the two discuss a real-world example: a smart factory where separate slices handle robotics, sensors, and admin traffic without interference. They also touch on the business implications, from new revenue models to the challenges of managing end-to-end slices across vendors. Tune in to understand how network slicing is not just a 5G buzzword but a practical tool transforming the edge.

In this episode of Networking Tech with Fexingo, Lucas and Luna explore why network operators are increasingly turning to Segment Routing MPLS (SR-MPLS) to simplify traffic engineering and automate path control. They start with a concrete example: a Tier-1 operator using SR-MPLS to steer traffic around a congested link in real time, avoiding expensive link upgrades. The conversation dives into how SR-MPLS replaces complex LDP and RSVP-TE protocols with a single label stack, making networks more programmable and easier to operate. They discuss the role of centralized controllers, the economics of bandwidth optimization, and why operators are adopting it now rather than waiting for SRv6. Practical takeaways include how to test SR-MPLS in a lab using open-source tools like FRRouting, and why operators should start by migrating unused LDP tunnels. The episode ends with a forward-looking question about whether SR-MPLS will remain relevant as IP networks evolve. Perfect for network engineers, architects, and anyone curious about the backbone of the internet.

In this episode of Networking Tech with Fexingo, Lucas and Luna explore why time-sensitive networking (TSN) is moving from the factory floor into the data center and even the internet edge. They focus on a real-world case: how a financial exchange in Europe deployed TSN over standard Ethernet to guarantee microsecond-level latency for trading traffic, sidestepping the cost of proprietary hardware. The conversation breaks down IEEE 802.1Qbv time-aware shapers, the role of precision time protocol, and how TSN coexists with traditional best-effort IP traffic. Lucas and Luna also discuss the challenges—like clock synchronization in virtualized environments and the need for network-wide configuration—and why hyperscalers and 5G providers are starting to experiment with TSN. If you've wondered whether Ethernet can ever be deterministic, this episode gives you the concrete details and the trade-offs. Tune in to understand why TSN could be the quiet revolution in networking.

In this episode of Networking Tech, Lucas and Luna explore deterministic networking — the effort to guarantee latency and jitter bounds over IP networks, not just best-effort delivery. They anchor the discussion in the IEEE 802.1 TSN standards and the IETF's DetNet working group, and they get concrete with a real-world case: a robotic control system in a smart factory where a delayed packet can halt a production line. The hosts explain how deterministic networking works, why it's becoming critical for industrial automation and 5G, and the technical challenges of scaling it beyond a single campus to a wide-area network. They also touch on the role of segment routing and network slicing in making deterministic guarantees practical. If you've ever wondered how the internet could ever support time-critical applications, this episode breaks it down with specific examples and a healthy dose of realism about the trade-offs.
