SIPp is a free, open-source tool for testing Session Initiation Protocol (SIP) communication systems. It was created to simulate thousands of simultaneous incoming and outgoing SIP calls, allowing users to stress test and measure the performance of their SIP infrastructure.

SIPp is a highly flexible tool, and its scripting language supports various SIP message types and parameters, allowing you to test the behavior of your SIP infrastructure in detail. It also supports SIP over Transport Layer Security (TLS) and Secure Real-time Transport Protocol (SRTP) for secure communication.

Titel: “Distributed Systems With Node.js”

Edition: 2020

Author: Thomas Hunter II

The book in my list that I was interested in reviewing was this one, which I thought might have some useful tips for my work.

This book, “Distributed Systems with Node.js” by Thomas Hunter, focuses on teaching readers how to use Node.js for building backend services for distributed systems, rather than frontend web development. The book covers topics such as deploying and scaling Node.js applications, making them redundant and resilient to failure, and observing the health of the application. By the end of the book, readers will have a solid understanding of the technologies needed to run Node.js services in a production environment. However, it’s important to note that the book is not intended to make readers experts on these systems and it doesn’t cover all the technology used in different employer’s solutions. But it will help readers to understand how to run a local instances.

Remote SIM Provisioning (RSP) is a method of managing and provisioning SIM cards remotely without the need for physical interaction. This enables mobile operators to remotely activate and configure SIM cards, and manage subscriber data such as phone numbers, services, and preferences.

Earlier this week, I read an interesting whitepaper from AWS about how public cloud providers are moving to 5G and optimizing their services to gain more market share. AWS in this whitepaper covers OpenRAN as one of these technologies, providing useful hints about new services around 5G SA networks. This whitepaper is a technical guide that describes the architecture and best practices for deploying OpenRAN solutions on the AWS cloud. The paper begins by providing an overview of OpenRAN and its key components, including the vRAN (virtual RAN) and CU (central unit), as well as the O-RAN (OpenRAN) Alliance and its goals.

Podman is a container engine that enables users to manage OCI-compliant containers on Linux systems without the need for a daemon. It is popular among users as an alternative to Docker due to its ease of adoption. However, the lack of support for Docker Compose, a command-line tool that coordinates multiple Docker containers for local development, has been a major concern for many users and the container community. Podman starts to support docker-compose from version 3.0 but changes in docker-compose from version 2.0 made some incompatibilities, so a community project called Podman Compose has been born. Podman Compose processes the Compose spec and translates it into Podman CLI commands [1].
