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

In June 2026, Border Gateway Protocol remains one of the internet's weakest links. Lucas and Luna examine the mechanics of BGP hijacks—how a single misconfigured router can reroute global traffic—using the 2024 X/Twitter hijack incident as a case study. They explore why RPKI adoption has stalled at 45 percent, the role of MANRS in improving routing hygiene, and what network engineers can do today to protect their prefixes. Specific numbers, real incidents, and a clear call to action for operators. No fluff.

The cloud is moving closer to users — and that breaks decades of routing assumptions. In this episode, Lucas and Luna examine how edge computing forces a fundamental rethink of network topology, using a concrete case: a regional retail chain deploying real-time inventory analytics at 50 local stores, routing traffic to local nodes instead of a central data center. They walk through the shift from hub-and-spoke to mesh routing, the role of DNS-based steering, and why BGP at the edge behaves very differently than in the core. No hype — just the engineering reality of delivering sub-ten-millisecond latency when the data center is a closet at your strip mall. Includes a natural listener-support moment early on.

In Episode 50 of Networking Tech with Fexingo, Lucas and Luna dive into MPLS Transport Profile (MPLS-TP), a technology that blends the predictability of circuit-switched transport with the efficiency of MPLS packet switching. They explore why telecom carriers and utilities still demand deterministic network behavior—using a concrete example of how a regional power grid operator uses MPLS-TP to guarantee sub-50-millisecond failover for SCADA traffic. Lucas explains how MPLS-TP eliminates IP routing's unpredictability by using static LSPs and OAM mechanisms borrowed from SONET/SDH, while Luna questions whether the trade-off in flexibility is worth it in an era of software-defined networking. The conversation covers real-world deployment challenges, including the 2018 FCC ruling on packet timing precision, and contrasts MPLS-TP with newer alternatives like Segment Routing. A must-listen for network engineers evaluating transport technologies for mission-critical infrastructure.

In this episode of Networking Tech with Fexingo, Lucas and Luna explore the technology behind Reconfigurable Optical Add-Drop Multiplexers (ROADMs) and how they are transforming long-haul fiber networks. They discuss how ROADMs enabled a single fiber pair to carry 400 gigabits per second across 3,000 kilometers without electronic regeneration, using a real-world deployment by a major US carrier earlier this year. The hosts explain the shift from fixed optical add-drop multiplexers to colorless, directionless, contentionless ROADMs, and how this technology underpins modern internet backbone scalability. They also touch on the role of wavelength-selective switches (WSS) and liquid crystal on silicon (LCoS) technology in making dynamic optical routing possible. Perfect for network engineers and anyone curious about the physical layer of the internet.

In 2011, Facebook launched the Open Compute Project, an initiative to redesign data center hardware from the ground up. This episode focuses on how OCP transformed networking equipment, specifically the switch design that broke the proprietary hardware model. We look at Wedge, the open-source switch operating system that Facebook built, and how it forced traditional vendors like Cisco and Juniper to change their pricing and licensing strategies. Lucas and Luna discuss the trade-offs between merchant silicon and custom ASICs, the impact on white-box switching, and whether OCP's model actually saved companies money or just shifted costs. A specific case: how a mid-sized cloud provider saved 40 percent on network hardware by adopting OCP gear, but had to double its software engineering headcount to manage it. The episode concludes with a look at the current state of open networking and whether the commodity hardware promise has fully materialized.

Episode 47 of Networking Tech with Fexingo dives into the overlooked backbone of global synchronization: Network Time Protocol (NTP). Lucas and Luna explore how NTP keeps data centers, financial exchanges, and 5G networks within milliseconds of each other, using a real-world example from the 2025 AWS time-sync incident that caused a 12-minute trading halt on the Nasdaq. They break down the leap-second debate, the coming deprecation of leap seconds by 2035, and why Google, Meta, and Microsoft each run their own NTP stratum strategies. If you've ever wondered how your phone knows what time it is — or why a 200-millisecond clock skew can crash a distributed database — this episode delivers the concrete mechanics.

Lucas and Luna explore the unsung hero of long-haul internet infrastructure: the erbium-doped fibre amplifier (EDFA). They explain how this device amplifies light signals without converting them to electricity, enabling transoceanic cables to carry terabytes per second. The episode drills into a 2025 upgrade of the SEA-ME-WE 6 cable system, where next-generation EDFAs increased capacity by 40 percent without laying new fibre. Lucas breaks down the physics simply, and Luna draws a parallel to noise amplification in audio systems. They discuss how EDFAs affect routing economics and latency, and why they matter for cloud providers and AI training across continents. The hosts also touch on the recent shift toward Raman amplification as a complementary technique., This is a standalone episode that assumes no prior knowledge of photonics or optical networking.

Episode 45 explores how the command-line interface — the decades-old backbone of network engineering — is being systematically replaced by automation and intent-based systems. Lucas and Luna break down a real-world case: a mid-sized financial services firm that moved from manual router configs to an automated CI/CD pipeline using Ansible and a network source-of-truth. They look at what was lost (deep CLI fluency, tribal knowledge) and what was gained (zero-config deploys, audit trails, faster incident response). Specific numbers: the firm's config-deployment time dropped from three hours per change to four minutes, and human-error-related outages fell from eight per quarter to zero. The conversation touches on how this shift changes the skills that matter for network engineers — and why some of the best operators are the ones who embrace the abstraction, not fight it.

Episode 44 of Networking Tech with Fexingo: Lucas and Luna dive into network observability — the practice of collecting telemetry, tracing packets, and using real-time data to predict failures before they cause outages. They break down how tools like eBPF, OpenTelemetry, and streaming telemetry are changing network operations, using a concrete example: how a major streaming service used observability to detect a microburst issue 90 seconds before it would have taken down their video pipeline. They discuss the difference between monitoring (looking at known metrics) and observability (exploring unknown unknowns), and explain why the shift from SNMP polling to streaming telemetry matters. No jargon overload — just the practical shift happening in network engineering right now.

Episode 43 of Networking Tech with Fexingo explores Multiprotocol BGP (MPBGP), the extension that enables a single BGP session to carry IPv4, IPv6, VPN labels, and even MAC addresses. Lucas and Luna break down how MPBGP works under the hood, why it's essential for modern data center fabrics like EVPN-VXLAN, and a real-world example from the 2024 Lumen network outage where MPBGP misconfiguration caused widespread reachability issues. They also discuss the role of BGP ADD-PATH in improving load balancing and fault tolerance. No prior BGP deep dive required — just a curious mind. Listeners will come away understanding why MPBGP is the Swiss Army knife of Internet routing.
