Latest addition to network testing and simulation: Containerlab

Until recently all existing virtual lab solutions were based on vendor appliances provided as virtual machines. Such an approach allowed us to emulate closely the real HW (some of those appliances had virtualized data planes as well - e.g. vEX, vMX). However this is not always the desired case.

Virtual Labs: running network topology on a plain laptop

For a very long time whenever someone wanted to create a network playground, they had to use physical equipment. Although such an approach had some pros, they were quickly outweighed by the cons, such as: price of equipment, manual cabling required to set up the environment, noise, power consumption - the list is long.

Linux as a network device

Using Linux as a network device can result in many benefits. Find out what network devices are and why it’s a good idea to use Linux as one. This is actually not an easy question to answer. In general, one can say that a network device is a piece of equipment whose main role is to forward packets or perform actions on them. While packet forwarding seems easy to understand, the actions that a packet can be a subject to differ between device types. For example, a router will (usually) route an IP packet based on a (OSI model) layer 3 header, a switch will use layer 2 for that, and a firewall can dig deeper into the packet payload.

The modern, interoperable DC — Part 3: Seamless and secure connectivity for edge computing and hybrid clouds (video)

In the third part of our “Modern DC” webinar series we focus on connectivity with resources located beyond the local data center, somewhere in the Internet. This includes extending Layer 2 and Layer 3 tunnels to public clouds (such as AWS, Azure and GCP), branch offices, Edge Computing servers and IoT devices based on single-board computers.
