The Open Systems Interconnection (OSI) model is a conceptual framework that describes how data flows from one device to another over a network. It is a valuable tool for network engineers because it provides a common language and understanding of how networks operate. Here are a few reasons why every network engineer should know the … Read more
The Open Systems Interconnection (OSI) model is a conceptual framework that outlines the fundamental principles of networking. It was developed in the 1970s by the International Organization for Standardization (ISO) to overcome the interoperability issues between different computer systems and networks. The OSI model is based on a layered approach, where each layer provides specific … Read more
The OSI model diagram is a fundamental tool that simplifies network communication by breaking it down into seven different layers. The model is an acronym for Open Systems Interconnection, and it is a conceptual, layered approach to networking. The OSI model can be compared to a blueprint or roadmap that helps network engineers to understand … Read more
As a network engineer, understanding the OSI model is essential for designing, implementing and troubleshooting network infrastructure. The OSI model is a conceptual framework that describes how data moves between devices and applications on a network. It is organized into seven layers, each with its own specific function. In this article, we’ll take a deeper … Read more
The Spanning Tree Protocol (STP) is a standard networking protocol designed to prevent loops in network topology by allowing for the creation of a single path between nodes. This ensures that data packets flow efficiently and smoothly across all network devices, without the risk of data loss or disruption. When multiple paths are available between … Read more
Spanning Tree Protocol (STP) is a network protocol that prevents the occurrence of loops in a network topology and ensures that there is only one active path between any two nodes in order to avoid broadcast storms. Spanning Tree Protocol (STP) is widely used in networks that span multiple VLANs and switches. Portfast is a … Read more
As network administrators, we are responsible for managing and maintaining the smooth operation of our organization’s network infrastructure. A significant aspect of this responsibility is to prevent network loops, which occur when there are multiple paths available for data to travel from one point to another. Network loops can cause network congestion, packet loss, and … Read more
As networks become increasingly complex, Spanning Tree Protocol (STP) has become a crucial feature for network administrators to ensure reliable network operations. However, things can go wrong with STP, and when they do, they can cause significant disruption to network service. Troubleshooting STP can be a challenging task, but there are several tips and techniques … Read more
Asymmetric routing is a common issue in network communication. It arises when incoming and outgoing traffic from a network takes different paths, causing delays and packet loss, which results in poor network performance. One such protocol that can handle this problem is Border Gateway Protocol (BGP). BGP is an inter-domain routing protocol that determines the … Read more
Asymmetric routing occurs when a packet takes a different path to return to its source than it did to reach its destination. This can cause problems in network performance, reliability, and security, so it’s essential to avoid these pitfalls. Here are some tips and best practices for avoiding the pitfalls of asymmetric routing. 1. Use … Read more
