About VLANs on Switches

About VLANs on Switches

Continuing the series of blogs posts on the most representative technologies to consider when selecting switches, this time we look at VLAN technology. VLANs arose from the need to isolate different stations operating on the same physical local network.  In addition, VLANs isolate different broadcast domains and help stations to avoid support excessive broadcast traffic, saving bandwidth and...

The Spanning Tree algorithm in Switching: a link between reliable and efficient networks

The Spanning Tree algorithm in Switching: a link between reliable and efficient networks

In the boundless realm of telecommunications, making sure networks run efficiently and undisturbed is crucial. Today, we are going to focus on the fascinating Spanning Tree algorithm (STP) and its relationship with switching. We will find out how this unsung hero keeps our networks free from loops and running smoothly.   The evolution of the Spanning Tree Protocol STP was developed by Radia...

Observability in IT networks

Observability in IT networks

In the ever-changing world of IT networks, observability has become crucial to ensure computer networks run safely and efficiently. The ability to understand and monitor the internal states of a system in real time has become essential in areas as wide-ranging as software development and system management. The term "observability" first appeared in Rudolf Kalman’s control theory and refers to...

Switches: Stacking/grouping/virtualization techniques

This blog post is the first in a series in which we will analyze the most notable technologies that we should take into account when selecting switches. Its aim is not to give a comprehensive description or follow any “didactic” order. One of the main characteristics of professional switches is the feature known as stacking, grouping or virtualization. Different manufacturers refer to this...

NetFlow collection: A new standard for advanced network monitoring

NetFlow collection: A new standard for advanced network monitoring

Data collection is an essential part of network management to ensure network devices are being efficiently monitored and managed. NetFlow and SNMP (Simple Network Management Protocol) are two widely used techniques for collecting network data. These two approaches are similar in that they both aim to provide valuable information about network traffic and device status. However, there are...
