Deep Dive into Related Topics

In summer 2020, James Miles sent us an awesome list of questions he got after watching the original webinar, resulting in another 2.5 hour of deep dive content focusing on various aspects of network operating systems.

1:23:05 Network Operating Systems Deep Dive

In the first set of questions we revisited the operating system basics and peculiarities of network operating systems, and concentrated on implementation details of Linux-based network devices.

36:56 Virtualizing Network Devices

The second set of questions focused on virtualized network devices used either for network simulation or packet forwarding, the performance challenges you might expect, the packaging format (virtual machines versus containers), and the operational implications of running network devices on top of a virtualization infrastructure.

29:32 Impact of Open NOS and Device Virtualization

The final set of questions addressed impact of device virtualization and open operating systems on hardware vendors, the impact on networking engineers, and the mandatory last question: Should network engineers become programmers?
