Heavy Networking

Heavy Networking is an unabashedly nerdy dive into all things networking. Described by one listener as "verbal white papers," the weekly episodes feature network engineers, industry experts, and vendors sharing useful information to keep your professional knowledge sharp and your career growing. Hosts Greg Ferro, Ethan Banks and Drew Conry-Murray cut through the marketing spin to explore what works—and what doesn't—in networking today, while keeping an eye on what's ahead for the industry. On air since 2010, Heavy Networking is the flagship show of the Packet Pushers podcast network.
