Network traffic troubleshooting during VNF lifecycle — aspects of Tungsten Fabric flows

Here’s a question that gives telco operators sleepless nights: How do you go about building and maintaining your telco cloud to maintain carrier-grade requirements while bringing hyper-scale public cloud pronouncements and promises to the telco world? One of the main challenges to achieving the above is to provide network monitoring, alerting and troubleshooting. Monitoring such complex infrastructure is not only about monitoring the physical health of the hardware the services rely on. It must also extend to the state of VMs or containers serving either control plane functions or a that runs a specific network function.

GPU in computer networks — how to speed up traffic processing

We are almost always online in our hyper-connected world. In just 10 years, the number of active device connections rose from 8.8 billion in 2010 to 21.6 billion in 2020, and it is expected to further increase to 41.2 billion by 2025 (according to Statista data). This rapid growth raises new technical issues regarding network traffic control and processing. Especially when we combine them with the development of 5G, a new standard offering peak data rates of up to 20 Gbps and supposedly supporting a 100-fold increase in traffic capacity and network efficiency.

MobX in React — learn the basics [Video Demonstration]

MobX and React are often used together to efficiently create component-based web applications. The process of integrating them can seem challenging at the beginning. This is why we haveprepared a comprehensive video guide for those who want to use MobX in React. Also known as React.js or ReactJS, React is an open source, JavaScript library that provides an output for data presented in HTML. The views of React are generally extracted through the deployment of “components.” These components can consist of additional components, which are specified in terms of custom HTML tags.

Rust vs C: safety and performance in low-level network programming

According to the Stack Overflow Developer Survey 2020, Rust is the most popular programming language. It won the title for the fifth year running, and the good news hardly ends there. Also in 2020, Linux kernel developers proposed including Rust in Linux Kernel, which was originally written in C. Quite recently, Facebook joined the Rust Foundation, an organization driving the development of the language Rust, with the intention of helping it go mainstream. Given all this, we decided to check if Rust can replace C in low-level network programming to ensure higher safety without sacrificing high performance.

How to build CNFs using Ligato framework

Cloud native network functions (CNFs) are a hot topic today. In this blog post, I will take a stab at explaining why and also present the Ligato framework, which allows you to build your custom CNFs. We started talking about Virtual Network Functions (VNFs) a few years ago when the concept of Network Function Virtualization (NFV) appeared. In short, it is that network functions can be deployed as virtual machines (VMs) instead of being delivered on dedicated hardware offered by vendors. Over time, telco operators and service providers launched their first field trials and then roll-outs of network functions based on this paradigm.

Why Vector Packet Processing is worth your time

The Vector Packet Processor (VPP) is a high-performance packet-processing stack that can run on commodity CPUs. In this article, I will take a closer look at what distinguishes this technology from others and how helpful it can be in meeting the demand for efficient network solutions. Regardless of the specific hardware or software implementation at the dataplane level, packet processing can be generally described as a sequence of operations that are performed on packets. This can be represented as a graph in which each vertex corresponds to an operation.

Microsoft Azure cost management in cloud-based software development

Software development, testing and R&D activities very often require considerable cloud resources. At the same time, these are dynamic environments which can lead to ballooning cloud costs. Public clouds such as AWS, GCP or Microsoft Azure have native mechanisms to manage and optimize spend, but they can’t prevent you from incurring unwanted and uncontrolled costs. This led us to create our own cloud cost optimization solution. In this, the final part of our three-part series, we will show you how to build an Azure cost management solution.

How to optimize GCP costs in cloud-based software development

Scalability, availability and high availability—these are the advantages that make public clouds a must have in modern software development. But they can cost you dearly if you don’t manage your cost spending carefully. In the second part of our three-part series on cloud cost optimization, we will show you how to get the GCP bill under control and avoid unexpected cloud costs. Following up on our initial blog about AWS, we’ll now turn to building a cost management solution for the second public cloud: Google Cloud Platform (GCP).

Tungsten Fabric as a Kubernetes CNI plugin

CNI (Container Networking Interface) is an interface between container runtime and network implementation. It allows different projects, like Tungsten Fabric, to provide their implementation of the CNI plugins and use them to manage networking in a Kubernetes cluster. In this blog post, you will learn how to use Tungsten Fabric as a Kubernetes CNI plugin to ensure network connectivity between containers and bare metals. You will also see an example of a nested deployment of a Kubernetes cluster into OpenStack VM with a TF CNI plugin.

AWS cost optimization — keeping cloud-based software development costs under control

Public clouds are now indispensable in modern software development. They offer flexibility, scalability and high availability. At the same time, cloud cost management can be tricky, and generate unwanted spend that will be a considerable burden for the overall budget of your software project. In our three-part series on cloud cost management, you will read how to keep costs under control in the three most popular public clouds: AWS, GCP and Azure. In this first installment, we will present our approach to AWS cost optimization.
