Traditional traceroute is a widely used and very useful tool, but it struggles to accurately trace load-balanced networks. In this episode, Dr. Justin Rohrer joins us to talk about Paris traceroute, an extension of traditional traceroute, and how it's used to trace paths on a network that uses flow-based load balancing, or in other words, most of the internet. Learn more about Paris traceroute in Phil's blog post, <a href="https://www.kentik.com/blog/the-power-of-paris-traceroute-for-modern-load-balanced-networks/" rel="noopener noreferrer" target="_blank">The Power of Paris Traceroute for Modern Load-Balanced Networks</a>.

Justin P. Rohrer, PhD., currently develops Internet-scale network measurement, monitoring, and analysis systems at Kentik.  His career as a network engineer began in the late 90s, which was followed by an academic role as a computer science professor and a decade leading a research lab focused on improving network resilience and survivability, during which he published over 50 scientific papers and articles in the field.  As part of his study of Internet resilience, Dr. Rohrer has run more than 100 Billion paris-style traceroutes.

The network is how we deliver the services and applications we use every day at home, at work, and when we're on the move. That means the network is more important than ever, but it's also more complex than ever. To effectively manage this entire system means having a holistic view of the network, or in other words, Total Network Operations. In this episode, Scott Robohn joins us to talk about TNops and why we need to rethink how we approach network operations.

Scott Robohn has 30+ years of experience in Internet infrastructure.  He’s served in a variety of roles in network operations / support, engineering, architecture, training, systems engineering, and technical sales leadership. Scott founded his own consulting company, TechSalesCraft, and is co-founder of the Network Automation Forum. He loves to keep learning about Networking, Automation, AI, Mobility, Security, Silicon, and more. He lives in Harrisonburg VA and enjoys spending time with his wife, 4 adult children, and 4 grandchildren.

The networking industry has declared that SNMP is dead, but is it? Is streaming telemetry all we should focus on today, or is SNMP still useful even in modern networking? In this episode, Chris O'Brien, Product Manager at Kentik, joins us to talk about the reality of SNMP and streaming telemetry and his thoughts on where the industry is headed.

Chris spent 10 years as a network engineer starting by manning the phones in the support department at a wireless ISP, helping customers trace cables and restart their computers. His experience culminated with leading network engineering at a company with 750 locations. Chris has always been obsessed with network monitoring, so when an opportunity popped up to build network monitoring tools, he jumped at it. Since then, he's been working with network and development teams to build monitoring solutions and has been fortunate to release some of the most popular and innovative network monitoring tools in the world
