Time to read: 3-4 minutes Quality of Service (QoS) is a critical feature in networking that enables network administrators to prioritize traffic based on specific requirements, ensuring that high-priority traffic receives preferential treatment over lower-priority traffic. QoS helps to guarantee the performance and reliability of critical network applications, such as voice and video, by ensuring that these applications have sufficient bandwidth and low latency. QoS works by assigning different levels of priority to various types…

Understanding MPLS: An Overview of MPLS Technology – Posted in: Network, Technology

Time needed to read: 5-6 minutes. MPLS (Multiprotocol Label Switching) is a high-performance networking technology that is widely used in large enterprise networks, service provider networks, and data centers. It is a packet-switched technology that operates at Layer 2 and Layer 3 of the OSI model, and it offers a number of benefits over traditional IP-based routing, including faster routing, better QoS (Quality of Service), and improved network security. MPLS is based on the concept…

Understanding Bidirectional Forwarding Detection (BFD) – Posted in: Technology

Time needed to read: 3-4 minutes. Bidirectional Forwarding Detection (BFD) is a network protocol used to detect faults in a communication link between two routers. BFD is designed to provide a fast and reliable method of detecting failures in the network and to provide an accurate and precise failover mechanism. BFD works by using a series of messages that are exchanged between two routers to detect faults in the communication link. These messages are sent…

Understanding SSL: How It Works and Why It Matters – Posted in: Technology

Time to read: 4-5 minutes. SSL (Secure Sockets Layer) is a widely used security protocol that encrypts data transmitted between a user’s browser and a website. It is an essential technology that helps protect sensitive information, such as login credentials, credit card numbers, and other personal data. SSL works by creating a secure connection between a user’s browser and a web server. When a user visits a website that uses SSL, their browser first sends…

Understanding VPN: What It Is and How It Works – Posted in: Technology

Reading time: 5 minutes In today’s digital age, online security and privacy are becoming increasingly important. One way to ensure both is through the use of a Virtual Private Network (VPN). In this article, we’ll explore what VPNs are, how they work, and the benefits they offer. A VPN is a network that allows users to securely connect to the internet by encrypting their online traffic. It creates a secure and private connection between a…

Mail SPF Record: A Guide to Understanding and Setting it Up 31/03/2023 – Posted in: Technology

Reading Time: 3-4 minutes. Mail SPF (Sender Policy Framework) is a mechanism that helps to prevent email spoofing, which is a common tactic used by spammers to forge the sender’s email address. By using SPF records, you can specify the servers that are authorized to send emails on behalf of your domain, and other mail servers can check this information to determine whether incoming emails are legitimate or not. Here’s how it works: when a…

DNS: The Phonebook of the Internet – Posted in: Technology

Time needed to read: 4-5 minutes. DNS stands for Domain Name System, which is an important aspect of the Internet. When you enter a website’s URL in your web browser, it sends a request to the DNS to find the IP address of the website. DNS acts like a phonebook for the Internet and converts human-friendly domain names into machine-readable IP addresses. The DNS system has a hierarchical structure, consisting of various servers that work…

BGP: The Routing Protocol that Powers the Internet – Posted in: Technology

Time to Read: 3-4 minutes. Border Gateway Protocol (BGP) is a protocol used to exchange routing information between different networks on the Internet. BGP is the routing protocol that powers the global Internet, allowing different networks to connect and communicate with each other. BGP is used by Internet Service Providers (ISPs) to exchange routing information with other ISPs. BGP is a path-vector protocol, which means that it selects the best path to a destination based…

GNS3: A Powerful Network Emulation Tool 30/03/2023 – Posted in: Linux, Network, Technology, Virtualization

Time to Read: 2-3 minutes. GNS3 is a network emulation tool that allows network engineers to simulate complex network topologies in a virtual environment. It provides a graphical user interface (GUI) that enables users to drag and drop network devices such as routers, switches, and firewalls, and then connect them together to create a virtual network. With GNS3, network engineers can test and troubleshoot network configurations without the need for physical network equipment. This makes…
