Strategic Trust-Building Among Ops, Engineering, Architecture - And Leadership

Billy Joel had it right: It's a matter of trust. Too often Operations, Engineering, and Architecture teams don't trust one another--and nobody trusts leadership (and vice versa!). Special guest (and PacketPushers host) Scott Robohn joins us to talk about how to build trust, and the special role of an Operations Architect. | LISTEN NOW

AutoCon2 Talk Summary: Step 0: Test the Network! - Danny Wade

At the Network Automation Forum‘s AutoCon2 conference held the week of November 18, 2024, Daniel Wade took on testing for network automation. Sure, you want to push a network configuration change. That feels high-value. That’s a measurable result. But it’s also a high-risk operation. How do you de-risk a config push? Testing.

Dan described unit testing, integration testing, end-to-end testing, and regression testing, explaining next that testing needs a baseline. A snapshot. | READ NOW

Drut.io's 2500 Series Launches With Co-packaged Optics & 32×100G On A Card

I chatted with Bill Koss and Simon McCormack about Drut's somewhat understated hardware announcement regarding their 2500 series last week. I've been watching Drut for a while now, and I've been waiting for this hardware since fall of 2024 when I got a pre-production sneak peek.

Why? What Drut's making isn't a fancy Ethernet or souped up Infiniband. Drut is asking--and answering--a different question entirely.| READ NOW

Router Forwarding Engines: Part 3 – P4 and SAI

Another installment from Russ White. Part 2 of this series looked at some interfaces that can get routing information from external processes into the table of a forwarding engine (FE). Installing external routing information into a forwarding engine is an increasingly common use case, but moving forwarding information from internal processes, such as locally running routing stacks, to the forwarding engine is the most common use case. | READ NOW

AutoCon2 Talk Summary: Building The Business Case For Automation Using Informal Channels - William Collins

At the Network Automation Forum‘s AutoCon2 conference held the week of November 18, 2024, Alkira's William Collins took on building the business case for automation using informal channels. That is, the human element of bringing a network automation program to life.

In a big enterprise, William pointed out that it's hard to have an impact. Somehow, bad ideas get implemented. Engineering voices don't get heard. But he got past these challenges. How? Extending the OSI model to layer 8 (the humans). | READ NOW
