Many engineers use the term VLAN in a broad way, often referring to any logical separation on a switch. However, a standard VLAN and a Private VLAN address different needs. Mixing them up can lead to network design mistakes.
OSPF, or Open Shortest Path First. OSPF is one of the most commonly used interior gateway protocols (IGPs) in enterprise and service provider networks. It’s fast, scalable, and supports complex topologies. Many WISPs use OSPF in their networks as well as other Service Providers.
The IP (Internet Protocol) packet header is a crucial part of how data is transmitted across networks. It contains vital information that helps routers and devices determine where the packet is coming from, where it’s going, and how to handle it. In this post, we’ll break down the structure of an IPv4 packet header, explain … Read more
Ethernet over IP (EoIP) is a protocol developed by MikroTik that allows the creation of a Layer 2 VPN tunnel between two MikroTik devices over an IP network. This is useful for extending local networks across remote locations. In this guide, I will demonstrate how to configure an EoIP tunnel using MikroTik version 7. Prerequisites … Read more

Multicast offers a solution for simultaneously distributing data to multiple recipients. One of the key protocols enabling multicast routing is Protocol protocol-independent multicast (PIM). In this blog post, we’ll delve into the world of multicast, understand its significance, and unravel the workings of PIM, shedding light on how these technologies optimize data delivery across networks. … Read more
Importance of Cable Management: Best Practices in Cable Management: Challenges and Solutions: Effective cable management isn’t merely about aesthetics; it’s a crucial element in ensuring data center operations’ reliability, efficiency, and longevity. As the digital landscape evolves, organized cabling becomes increasingly indispensable in maintaining seamless operations in data centers.
In the vast and interconnected landscape of the digital world, data packets are the unsung heroes that power our online experiences. These small, seemingly unremarkable data units are like the “Little Engine That Could,” tirelessly chugging along to ensure our emails, videos, and messages reach their intended destinations. In this blog post, we embark on … Read more
What is QoS? Quality of Service (QoS) is a set of techniques and mechanisms that ISPs use to manage and prioritize network traffic. It allows ISPs to allocate network resources in a way that ensures certain types of data or applications receive preferential treatment over others. QoS is essential for delivering a consistently high-quality internet … Read more
