On today’s Heavy Networking we explore the intersection of policy, politics, and technology with the Internet Governance Project (IGP), which connects tech and policy experts to help bridge gaps in understanding between these two communities, with the goal of influencing outcomes on issues such as free expression, privacy, and security.
Will the new QUIC protocol cause the Internet to collapse? Today’s Heavy Networking episode tackles this question with guest Christian Huitema. QUIC is an emerging transport protocol that promises advances over TCP and the ability to innovate quickly, but could–possibly–set off an arms race as developers try to game congestion algorithms to their own benefit.
On today’s sponsored Heavy Networking episode we explore how AppNeta wraps user metadata around Netflow records, deep packet inspection, and discovery of networks to help engineers get a continuous view of end user performance and the telemetry to find and fix problems.
On today’s sponsored Heavy Networking, VIAVI Solutions joins the Packet Pushers to discuss the intersection of network performance management (NPM) and security. We discuss how network and security teams can leverage VIAVI’s packet capture capabilities, how it enriches flow records with additional data to provide valuable context, and how the concept of end user experience informs VIAVI’s approach to NPM.
AWS Transit Gateways, an evolution of Transit VPCs, centralize VPN connectivity to multiple VPCs, allowing for greater scale and simpler connectivity and management. Today’s Heavy Networking drills into this topic with guest Nick Matthews, an AWS solutions architect. We also examine Global Accelerator and TLS termination on Network Load Balancer.
On today’s Heavy Networking, three SD-WAN analysts walk into a podcast. We talk deployment strategies, hear advice on how to build a vendor shortlist, get insights about the operational challenges and cost considerations, and more.
InterOptic returns in this sponsored podcast to explore emerging trends in optics, including the rise of 400G, the differences between OSFP and QSFP, and the state of silicon photonics. Our guests are Robert Coenen, VP of Business Development at InterOptic; and Tim Doiron, Principal Analyst, Intelligent Networking at ACG Research.
Today in our Future of Networking series I speak with Guido Appenzeller. He’s been deeply involved in SDN and held key roles at Big Switch Networks and VMware, and now a new job at Yubico. We talk about the role of public cloud in IT, where the industry is with the adoption of “software-defined,” the rise of whitebox, the P4 programming language, and more.
Forward Networks returns to Heavy Networking to discuss its approach to network modeling, verification, and assurance in this sponsored episode. We explore new features, including the ability to leverage Forward’s data model for other applications and management systems, and its support for NSX-V and AWS VPCs.
On today’s Heavy Networking we discuss DNS Flag Day, the day a group of DNS software and service providers ended backwards-compatibility with domains that don’t support EDNS. We also discuss the potential impact on non-compliant domains. Our guest is Cathy Almond, Sr. Support Engineer and Team Lead at the Internet Systems Consortium.
Today’s Heavy Networking aims to separate the hype from the substance on hot tech topics including SD-whatever, cloud native, container networking, service meshes, microsegmentation, and more. Our guests are Avi Freedman and Jon Mendoza.
What does it take to build a gaming network for the largest LAN party in Australia? In today’s Heavy Networking podcast we find out. Our guest is Tim Raphael, who volunteers for Red Flag LANfest, a non-profit that runs Bring Your Own PC (BYOPC) gaming events in Perth, Australia.
On today’s Heavy Networking we discuss advanced ZTP features in Cisco’s IOS-XR in this sponsored episode. Our guest is Akshat Sharma, a Technical Marketing Engineer at Cisco.
Today’s Heavy Networking continues a conversation about the broadcast industry’s transition to IP. We consider the challenges IP networks face when implemented in a broadcasting environment, and why IP is moving ahead anyway. Our guests are Ricki Cook and Cyrus Hira.
Today’s episode introduces Heavy Networking, a rebrand of the Packet Pushers’ Weekly Show. We’ve renamed this podcast to better reflect its deep dive into networking technology and skills, and better differentiate it from other infrastructure shows in our podcast network. We also dive into key trends that will impact your career.
Today’s show dives into issues around IT supply chain security and mechanisms such as trusted execution. We examine how they work and how they’re implemented, and look at similar measures in routing and switching.
On today’s Weekly Show we dive into microsegmentation with our sponsor, Illumio. We discuss how Illumio builds an app dependency map in the data center to inform security policies, and leverages existing controls on hosts and in networking gear to cordon high-value workloads and contain attacks.
The Weekly Show returns to the University of Idaho to continue the real-world network design session we started in Show 418. Today’s episode focuses on the university’s wireless architecture and design with guests Brian Jemes, Mike Rusca, and Jake Snyder. We cover 5Ghz, PoE, next-gen APs, and more.
You need to know a cloud provider’s network performance before you spin up workloads because the end user impact is measurable. On today’s Weekly Show, sponsor ThousandEyes breaks down latency, jitter, and performance numbers for AWS, Azure, and GCP.
Today we discuss actual network design challenges with two network engineers at the University of Idaho, including firewalling and microsegmentation, identity management in the wireless network, and a home-grown network management system.
