In-band network telemetry — what is it all about?

In-band network telemetry is one concept from a wide range of available solutions for network telemetry. If you want to know what this approach is all about and how it has been adopted so far, please read on. Over the years, a wide variety of protocols, methods, and tools have been developed for network telemetry. These solutions are quite diverse and are used depending on the specific context and needs. Some time ago, one more concept appeared on the map: in-band network telemetry. The approach here is to gather so-called telemetry metadata for packets traversing network segments.

Data Science vs. Data Analytics — main differences overview

We live in a world where data is ubiquitous. Websites track all their users’ every click. Your phone carries a map of where you are and where you’ve been. Smart homes record information about their occupants and sales sites collect data about your buying habits. More and more people want to look for usable information in the data, to draw practical conclusions. This interest in data has developed rapidly and widely with the consequence that companies are looking for professionals with data-driven skills to deal with specific data problems.

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.

What is microservices architecture — types, tools, pros and cons

If you try to imagine an employee of a large organization who is supposed to run an entire business process on their own, from start to finish, and describe that hypothetical worker to anyone, it will definitely raise a few eyebrows. Indeed, it is strange to think that just one person should be in charge of, let’s say, purchases, accounting and maintenance at the same time. However, until recently, it was perfectly normal to expect the same from an app. Monolithic architecture used to be the main approach to building an application, and a lot of apps are still built as a single service.

What is Policy Based Routing (PBR)?

Nowadays, network traffic nature becomes very complicated in terms of the mixture of applications and their connectivity requirements. Achieving these requirements by means of traditional routing mechanisms may become cumbersome or even impossible and requires special dedicated solutions. Additionally, organizations need to focus on operational costs more strictly than in the past. One good direction to achieve this goal is the optimization of resource usage within different domains. Networking is one such domain, where the objective is to rationally maximize the usage of existing infrastructure rather than making an investment in increasing its capacity.

VLAN vs. VXLAN — what’s the difference and is one better than the other?

VM, VDI, VIM, NFVI, VLAN, VXLAN, VNF - the famous ‘V’ that dominates today’s IT world stands, of course, for ‘Virtual’. Every day we use virtualized servers, storage, desktop or networks without even realizing it. The convenience, cost-saving, enhanced features and security are just some of the reasons why we start using virtualization and often never look back. The same is true for computer networking, where a single physical network can host multiple separated, logical (virtual) networks that may have different topologies and feature sets or even carry traffic of different customers without interfering with each other.

Everything you should know about Requirements Engineering

According to Harvard Business Review, more than half of projects fail due to poor management. One of the biggest reasons for project failure is poorly handled requirements, which can derail a project at any point. To mitigate the project failure risk, you need to define the client’s needs and have a proper process that will transform those needs into actionable requirements. In this article, we will tell you more about requirements engineering and its process. As process management seems to be one of the most important aspects of software development, we will also cover some crucial mistakes to avoid.

Sentiment Analysis. What is it and how to use it?

During face-to-face conversations or by reading text - we, people, can determine a speaker's intention or mood, whether they feel happy about something or not. We can also identify the polarity of the context - is the expression positive or negative or maybe even neutral? It is relatively easy for most people, but do computers understand emotions? Is it important for machines to understand humans’ intentions? With the technological progression and advancement of machine learning techniques - our machines are getting closer and closer to answering these questions.

HTTP/3 Protocol — Performance and Security Implications

Web browsers use various protocols to deliver to users what they need. The best-known internet protocol is called HTTP. And just like any other technology, it is not immune to change. Read the article to learn about the HTTP protocol's history and compare its newest versions. The Hypertext Transfer Protocol (HTTP) is the foundation of the World Wide Web and is used to load web pages using hypertext links. HTTP is an application-layer protocol designed to transfer information between devices and runs on top of other layers of the network protocol stack.

AI and Machine Learning landscape for networks [infographic]

Aritifical intelligence (AI) and machine learning (ML) is a trending topic in all technological domains. It offers a rich set of methods for data processing that can be used to solve practical problems, including those occurring in networks. In this article we present a set of network issues for which the use of ML methods and different AI types can bring benefits and generally seems to make sense. Please note that this is a non-exhaustive list and is open to additions. For greater clarity, five main categories have been used.

FD.io’s VPP’s mechanical sympathy – thread and memory management techniques explained

We've previously explained how VPP processes packets in vectors as opposed to processing each packet end to end. But how is this processing spread across CPU cores? How exactly is a vector of packets structured?
