Introduction In computer networks, data communication is crucial for many applications as well as services. Data communication is the data transmission process over a network between multiple devices. It is important to note that various devices support different data formats, transmission speeds, and protocols. Hence, there is a need for a common network technology that […]

Introduction One of the foundations of modern networking is the border gateway protocol or BGP. Without BGP working in the background to allow system communication, the modern internet as it is known today would not be able to operate. The routing protocol known as BGP has two different versions, i.e., eBGP and iBGP. Both provide […]

Introduction Redundancy is a crucial component of every modern network. In this digital era, staying without a network for even a short time is hard. You should include some redundancy if you don’t want your firm to cease operating. All of your devices will stop communicating with the outside world if the default gateway fails […]

Introduction Nowadays, attackers’ knowledge and sophistication level is increasing steadily, making a single defensive method against intruders insufficient in providing substantial security. Instead, organizations should prioritize implementing a comprehensive and multi-layered strategy that combines proactive and defensive measures to safeguard their network and assets from unauthorized individuals. That’s where IDS, IPS, and firewalls come into […]

Introduction Today’s data transmission demands can’t be met by the inefficient and resource-intensive unicast method used by most networks. Internet Group Management Protocol (IGMP) Snooping was developed as a solution and is now often implemented in network multicast mode. In this blog, we will explain IGMP snooping, its working, functions, and applications. Let’s begin with […]

Introduction The management of a network on a major scale is not easy. As networks continue to grow in size and complexity, network engineers are faced with the challenge of determining optimal routes for handling the substantial volume of traffic flowing through them. Subnetting is one of the solutions developed, but the question is, what […]

Introduction Generic Routing Encapsulation, or GRE, is a tunneling system that allows various network layer protocols to be encapsulated within IP tunnels. Using either public or private networks, GRE may establish point-to-point logical links between network devices. In this blog, we will explain the GRE protocol with its working, benefits, drawbacks, and configuration. What is […]
