Network Interface Card (NIC) Testing — the optimal environment setup

As we can see in Ethernet Alliance’s 2023 Roadmap, we can now use link speeds up to 400Gb/s. Speeds 800Gb/s and 1.6Tb/s are “in development” and 3.2Tb/s is marked as a “possible future speed” for the 2030s. Compared to 10Mb/s in the 1980s, now we have devices functioning 40,000 times faster! With such acceleration, Jules Verne’s “Around the World in Eighty Days” would be called “Around the World in 2.88 Minutes”. The goal you need to achieve during test environment preparation is that the tested network interface card (also called a NIC, network interface controller, or network adapter) will be a bottleneck in the hardware configuration.

Bazel build system: build containerized applications faster

For the last nine months, I’ve been working on a large migration of multiple interconnected software projects from the CMake to the Bazel build system. While doing so, I’ve learned about Bazel’s capability for building and publishing container images. Bazel is a multi-language build system with a strong focus on hermeticity, which means that when given the same source code, Bazel will produce the same build artifacts, even on different machines (if properly configured). This property allows you to set up a remote cache for the artifacts that you can share between your developers and continuous integration (CI) system to significantly speed up your workflow.

GitOps vs. DevOps — what is the difference?

The world of software development is constantly evolving, with new approaches and methodologies emerging to improve the efficiency and effectiveness of the development process. Two of the most popular methodologies are GitOps and DevOps. While they share some similarities, there are also some key differences between them. DevOps is a methodology that emphasizes collaboration and communication between development and operations teams. The goal is to streamline the development process, reduce time to market, and ensure high-quality software.

Introduction to time series for machine learning

Data is becoming an integral part of everyday life. Even if we are not fully aware of it, we deal with it all the time and it affects our lives in significant ways. This blog post elaborates on a particular type of data: time series. If you want to know more and discover what problems you can solve with time series analysis, you've come to the right place. Have you ever wondered how much data is created (including newly generated, captured, copied, or consumed data) each day? Currently it is 0.33 zettabytes every day!

Detecting patterns, uncovering insights: the crucial role of data monitoring

In our digital era, data is a crucial resource for a wide range of industries. The ability to manage, interpret, and derive insights from the overwhelming flood of information is essential. This is where the role of data monitoring becomes significant - a process that oversees and reviews data to ensure its quality, assess system performance, and guarantee data security. Data monitoring is a well-structured method that provides a comprehensive understanding of the state and flow of data throughout its life cycle.

The importance and benefits of unit testing

Ensuring code quality and reliability is critical in the modern software development world. One of the possible solutions to achieving this goal is unit testing. Unit testing involves breaking down software into smaller components or units and subjecting them to rigorous testing. It helps identify bugs and errors early on and provides benefits that significantly enhance the development process. In this article, we delve into the importance of unit testing and explore its various benefits to developers and businesses.

AI and Machine Learning for Networks: natural language processing and reinforcement learning

This is the third part of the series, where we focus on the next two classes of ML methods: natural language processing and reinforcement learning. Also, we outline the major challenges of applying various ideas for ML techniques to network problems. This part also summarizes all three parts of the blog post. The first part can be found here, and the second part can be found here. Natural language processing is a part of AI which allows computer programs to understand statements and words written in human language.

Hardware offloading in software-defined networking

Increasing demands on computer hardware means higher demand for network technology. Unfortunately, computer systems remain largely inefficient, with the CPU serving as the key engine in a variety of computer applications. To solve this problem, one could take various approaches: use a bigger computer, distribute the software between different computers, or improve its performance. In this article, we'll show you how a higher-end computing device can reduce CPU usage and the costs associated with hardware.
