  • Deep dive into both current

    Heavy Networking is a deep dive into up and coming and relevant technologies in our business. And they get on experts that show you the practical applications of the technologies and how you're going to use it, what situations you're going to use it in, so that you're aware of what's out there. What I think is important is that they're both currently widely deployed technologies and the stuff that's still on the startup scene that you probably don't want to deploy yet. But in three years it's go... more

  • Such a wealth of knowledge! 🧠

    This is one of the most insightful podcasts that I have ever come across! The Packet Pushers team does such a great job of sharing their wisdom and I love how they lead meaningful conversations with guests who bring so much experience to the table. If you’ve got a question related to anything “networking technology” this is definitely the place to go. Highly recommend checking this show out - you won’t be disappointed!

Talking Points

Recent interactions between the hosts and their guests.

HN817: Is There a Better Way to Do Software Defined Networking?
Q: How feasible is incremental deployment for operators with existing infrastructure?
Incremental deployment is feasible by using separate VRFs or tiered priorities, allowing some destinations to be managed by DSDN while preserving existing routing elsewhere. This brown-field approach minimizes risk and enables gradual migration.
HN817: Is There a Better Way to Do Software Defined Networking?
Q: What are the practical data-plane options when implementing DSDN, and how do they impact deployment?
The data plane can use MPLS label stacks with innovative encoding to extend label capacity, SR, or SRv6. The implementation is modular, so operators can choose the most compatible data plane, and the controllers on routers coordinate via GNMI and other telemetry interfaces. This flexibility supports in-box control without forcing a single hardware path.
HN817: Is There a Better Way to Do Software Defined Networking?
Q: Alex, could you summarize how DSDN changes the traditional separation of control and data planes?
DSDN collapses the separation by placing the control logic directly on each router, running a full SDN controller instance locally, and using flooding to build a shared, global view. This enables fast, local decision-making with a consistent global picture, while avoiding the fragility of a single centralized controller.
HN815: All About PCE
Q: How widely supported is the Path Computation Element Protocol on your various router OSes?
PCEP is supported across most major vendors, particularly on service provider-oriented routers.
HN815: All About PCE
Q: What problems does PCE solve that traditional routing cannot solve?
PCE enhances traffic engineering by allowing more complex path computation beyond traditional shortest-path methodologies.
