Heat Transfer in network equipment
Heat transfer is a crucial part of how any electronic equipment works. When devices are operating, their internal components generate heat, and that heat needs to be dissipated in a controlled way. Doing so ensures safe and reliable operation, helps maintain optimal performance, and reduces the risk of unexpected failures. In short, good thermal management plays a...

Peer-to-peer networks
Cryptocurrencies have been hailed as one of the greatest technological revolutions of recent years. Bitcoin is the pioneer and best-known of them, but there are hundreds more – each with different characteristics, objectives and technologies behind them to make them...
Segmentation in SD-WAN
The SD-WAN market is gaining more and more strength; software-defined and managed connectivity solutions provide ever more possibilities and functionalities to adapt to the reality of business networks. One of the key aspects that all companies value is security. In...
Moving towards a fully encrypted Internet: DNS encryption and ESNI in TLS
Web browsing first began as a system lacking in privacy that allowed users to view simple content in text mode. Since then, the service has evolved in both functionality–allowing you to view complex designs–and in its access methods–said web content can be downloaded...
High-speed Internet from space: The Starlink network
Accessing the Internet from space is not new, with many companies (OneWeb, Space Norway, Telesat, etc.) now offering it. More recently, however, a new participant has emerged on the scene promising something different – Starlink. SpaceX’s plan is to create a network...
DTLS security over UDP
DTLS (Datagram transport Layer Security) is a protocol that provides privacy for UDP communications. To understand DTLS, you first need to understand UDP. UDP (User Datagram Protocol) is a transport layer protocol based on the exchange of datagrams (encapsulated in...
Web components – understanding the technology
Web Components is a standard introduced by the W3C for creating new elements for the web. It also allows developers to easily reuse and extend both the developed components and native elements. As they are part of the browser, no external library like jQuery is...
Microservices, Dockers and Kubernetes
Many companies today are opting for microservices-based architecture. And this most certainly has to do with the fact that microservices are a perfect complement to SDN/SD-WAN technology, allowing the modules that make up the applications to be implanted in numerous...
Fixed Wireless Access – Why 5G-FWA can succeed
In my previous blog post last week on 5G, we saw how Fixed Wireless Access (FWA) is considered a cornerstone use case for 5G and a new source of revenue stream for both MNOs and CPEs manufacturers. But if LTE is already capable of reaching extremely high Broadband...
Fixed Wireless Access – primary use case for 5G
Fixed Wireless Access has huge opportunities and challenges for the Telecom Industry with the deployment of the 5G system, but why is so important? Up to now, LTE is still considered the fastest developing mobile technology ever. Since its launch in early 2010, it has...
