What sort of Whitebox network ? Ethernet or X86 network appliance ?
Today on the Priority Queue, we re gonna hide some information. Oh, like route summarization? Sure, like route summarization. That s an example of information hiding. But there s much more to the story than that.
Our guest is Russ White. Russ is a serial networking book author, network architect, RFC writer, patent holder, technical instructor, and much of the motive force behind the early iterations of the CCDE program.
The latest tome to flow from his keyboard (and mine, actually) is Computer Networking Problems and Solutions available on Amazon right now. While I wrote or contributed to several of the chapters in this book, Russ did the lion s share, and we re going to dive into one of his book chapters, devoted to the topic of information hiding.
We discuss the reasons for information hiding in the control plane, including resource conservation and reducing the failure domain; the pros and cons of dividing a network in multiple failure domains with information hiding; and the criticality of convergence.
We also talk about techniques for information hiding, including filtering reachability information and using overlays.

Today on the Packet Pushers Priority Queue, we get nerdy about disaggregation, where you mix and match software from one vendor and hardware from another.
Our sponsor today is Cisco, and if you just did a double-take, that s right, Cisco wants to talk to you about disaggregation, but there’s more to it than just hardware/software separation.
Joining us are Bhavna Prasad, Product Manager at Cisco; and Akshat Sharma, Technical Marketing Engineer for Cisco s Service Provider BU.
We discuss the different kinds or degrees of disaggregation, and then drill into specifics around IOS-XR.
We also look at the programmatic capabilities and interfaces of IOS-XR, what hardware it’s available on, use cases, and more.

Cloud native applications are designed to be managed by software in all stages. This includes ongoing health checks as well as initial deployments. Human bottlenecks should be eliminated as much as possible in the technology, processes, and policies.
That quote is from the O Reilly book Cloud Native Infrastructure. On today s Datanauts episode, we talk to Justin Garrison, one of the authors and a senior systems engineer.
We dive into the chapter about managing cloud native applications, including a general conversation about the definition of a cloud-native app–that is, an application managed by software rather than humans.
Then we discuss the challenges of managing a microservices architecture, explore the concept of sidecar proxies, and walk through the process of deploying a new cloud application into production.
We also look at troubleshooting tools and techniques, and examine the necessity of service discovery and resource scheduling.

Our next installment of the Future Of Networking series brings Peter Wohlers to the podcast.
Way back in the early history of Packet Pushers, we received a presentation from Peter when he worked at Force10 as part of a Tech Field Day event. It was blunt, knowledgeable, cynical and nerd-funny.
Today Peter is VP of Engineering at a large CDN. I invited him to come on talk about the current and future state of the industry.
We discuss the effect of cloud computing on the networking industry and its impact on skills and careers, the early hype around SDN and where it stands today, how much skill you really need in coding, the rise of APIs in networking, and a passionate debate about whether different networks are actually all that unique.
