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, The Power of Paris Traceroute for Modern Load-Balanced Networks.

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.

In this episode, Avi Freedman joins us again to talk about "enrichment", or in other words, adding additional context to our more traditional network telemetry so that we can truly understand what's happening in our network and with application delivery.

For years, routing on the global internet has been built mainly on trust relationships. There has been little to protect the entire internet community from accidental or intentional spoofing of IP address spaces and autonomous systems, and there was very little governance protecting the security of routing among providers other organizations with an internet presence. 

In this episode of Telemetry Now, Aftab Siddiqui, Senior Manager of Internet Technology for the Internet Society, joins us to discuss MANRS, or the mutually agreed norms for routing security, which was started specifically to set forth security principles and guidelines for routing security on the global internet.

Historically, the internet has operated on a sort of trust relationship. Trust among those advertising their own networks out to the world and trust from those learning about those networks. But there hasn’t been much to prevent anyone from advertising incorrect information, and therefore manipulate where others send their traffic sometimes to the extent that traffic might even be blackholed causing outages. In this episode of Telemetry Now, Job Snijders, Principal Engineer at Fastly and a prolific contributor to efforts securing global routing, joins us to talk about how we can secure global internet routing with technologies such as ASPA, RPKI validation, Peerlock, and to an extent, BGP Security.

Today's cybersecurity landscape is about less about knowing all about hashes and encryption, and more about understanding data, politics, and how adversaries operate in the real world.
