What can decades of hands-on operational experience teach us about the future of AI-driven networking?

In this episode of Next-Gen Network Heroes, host Bob Slevin sits down with Jeremy Bradberry, Senior Network Engineer at Delaware North, for a conversation that spans everything from legacy manufacturing systems and mainframes to modern AI-assisted network operations. Jeremy shares how his early career working in industrial environments shaped the way he approaches networking today, giving him what he calls an “X-ray vision” into how technology connects directly to business operations.

Jeremy explains why understanding operational workflows is just as important as understanding the technology itself. Drawing from real-world experiences modernizing aging infrastructure in manufacturing environments, he shares how practical problem solving, adaptability, and business alignment helped him create innovative solutions long before AI entered the picture.

The conversation then shifts into how AI is changing the daily life of network engineers. Jeremy walks through practical examples of using tools like Copilot and Lucid to analyze large datasets, accelerate troubleshooting, automate documentation, and improve collaboration across teams. Rather than viewing AI as a replacement for expertise, Jeremy sees it as a force multiplier that gives engineers more time to focus on strategy, improvement, and innovation.

Bob and Jeremy also discuss the importance of mentoring junior engineers, preserving strong operational standards, and ensuring organizations don’t lose sight of the fundamentals while adopting new technology. The episode closes with a fun look into Jeremy’s passion for retro gaming, console preservation, and how gaming culture unexpectedly parallels the world of networking and systems engineering.

Takeaways:

• Understand the business behind the technology. The best network engineers don’t just know the infrastructure; they understand the operational impact when systems fail and how technology supports the business as a whole.
• Modernization doesn’t always require a complete rebuild. Jeremy shares how creative solutions helped extend the life of legacy systems while still introducing modern networking capabilities.
• AI works best as a force multiplier, not a replacement. Tools like Copilot can dramatically speed up troubleshooting, reporting, and documentation, but strong technical knowledge is still essential.
• Better standards create better AI outcomes. Consistent naming conventions, interface descriptions, and operational discipline make AI tools significantly more effective.
• Focus on asking the right questions. AI can surface insights quickly, but engineers still need the experience and operational understanding to guide investigations and validate results.
• Use greenfield projects strategically. New deployments are opportunities to build future-ready environments that support automation, visibility, and scalability from the start.
• Operational experience builds resilience. Jeremy’s early career in manufacturing environments taught him persistence, adaptability, and how to solve problems under pressure.
• Collaboration improves outcomes. Sharing AI-driven insights across teams helps break down silos and allows organizations to solve problems faster and more effectively.

What does it take to succeed in networking when complexity is constantly increasing, and change never slows down?

In this episode of Next-Gen Network Heroes, host Bob Slevin sits down with Troy (David) MacDonald, a network engineer at Blue Origin and former U.S. Army Chief Warrant Officer, to explore a career that spans from infantry beginnings to designing and managing large-scale, mission-critical networks.

Troy shares how his unexpected entry into technology sparked a lifelong curiosity, from discovering dial tones in the desert to building modern fiber and satellite-based networks. Along the way, he developed a powerful “superpower”: the ability to translate complex technical needs into real-world solutions for stakeholders.

The conversation dives into the realities of scaling networks in fast-growing environments, the challenges of monitoring and alert fatigue, and where AI can meaningfully improve operations without replacing human judgment. Troy also reflects on leadership, teamwork, and the importance of setting aside ego to build stronger, more collaborative network teams.

From military lessons to modern enterprise challenges, this episode is a grounded and insightful look at what it really takes to operate and evolve networks in the AI era.

Takeaways:

• Start with conversation, not assumptions: Great network design begins with understanding real needs—not jumping straight to solutions. Taking the time to ask questions and clarify requirements prevents overengineering and builds trust with stakeholders.
• Communication is a core technical skill: Networking isn’t just about infrastructure—it’s about translating complexity. Clear, consistent communication throughout a project is what keeps teams aligned and systems running smoothly.
• AI’s biggest opportunity is reducing operational noise: One of the most valuable use cases for AI today is filtering alerts, identifying root causes, and reducing unnecessary escalations so engineers can focus on what actually matters.
• Automation should be trusted—but verified: While AI and automation can handle repetitive tasks, human oversight is still critical. The balance between efficiency and validation is where real value is created.
• Strong teams are built on trust, not ego: High-performing network teams leverage each other’s strengths and operate collaboratively. Letting go of an ownership mindset and embracing shared responsibility leads to better outcomes.
• Growth amplifies complexity—and exposes gaps: Rapid organizational growth can quickly overwhelm monitoring and operations. Iteration, prioritization, and continuous refinement are essential to keeping systems manageable.
• Curiosity is the foundation of a great career: From shortwave radios to satellite networks, staying curious and exploring new technologies drives long-term growth and opportunity in this field.

What happens when deep networking expertise meets low-level programming and a passion for invention?

In this episode of Next-Gen Network Heroes, host Bob Slevin sits down with Liang Chen, Senior Network Architect at Texas Children's Hospital and a true innovator in network performance and visibility. With more than 25 years of experience in networking, plus advanced expertise in programming languages like C and Assembly, Liang has built his own next-generation traffic analysis platform from the ground up—designed to provide real-time, packet-level visibility at massive scale.

Liang shares how his background in telecom helped shape his career, from building public IP networks in China in the early days of internet infrastructure to solving mission-critical performance challenges in healthcare today. He explains why traditional tools like SNMP and NetFlow can only go so far, and how his invention—EngineTA, a next-gen network traffic analyzer—captures and analyzes traffic at up to 200Gbps with zero packet loss. The conversation also explores AI in healthcare, troubleshooting large-scale imaging transfers to the cloud, and why research, curiosity, and persistence are essential for any network engineer looking to solve brand-new problems.

Takeaways:

• Traditional visibility tools have limitations: SNMP and NetFlow-based tools provide useful insights, but they often miss the full picture. Liang explains why sampled data isn’t enough when troubleshooting complex performance issues and why true packet-level visibility matters.
• Packet-level analysis unlocks deeper troubleshooting: Liang’s tool analyzes every packet in real time, allowing teams to identify retransmissions, packet loss, latency, and asymmetric traffic paths faster and more accurately.
• Zero packet loss is critical in network forensics: When troubleshooting sensitive environments like hospitals, missing even a small amount of data can hide the root cause. Complete packet capture ensures nothing gets missed.
• Healthcare networks are mission-critical: At Texas Children’s Hospital, the network is a life-saving infrastructure. Fast root cause analysis and high availability are essential for patient care and operational continuity.
