How Does Packet Flow in Network?
Introduction Packets are the basic units of data that are transmitted over a network. A packet is a small piece of information that contains the source and destination addresses, the data itself, and some additional information for error checking and routing. Packets are sent from one device to another through various intermediate devices, such as […]
What is PIM Protocol (Protocol Independent Multicast)?
Introduction Multicast is a technique that allows one source to send data to multiple destinations simultaneously without duplicating the data packets. This can save bandwidth and improve network efficiency, especially for applications that involve streaming media, online gaming, video conferencing, or distributed computing. However, multicast routing is a challenging task, as it requires the network […]
What is Network Function Virtualization (NFV)?
Introduction NFV stands for Network Function Virtualization, and it’s a way of running network services, such as routers, firewalls, and load balancers, on virtual machines (VMs) instead of physical hardware. This means one doesn’t need to buy expensive and specialized hardware for each network function. One can just use standard servers and run multiple functions […]
What is Cisco ASA (Adaptive Security Appliances)?
Introduction Nowadays, network security is more than crucial for any organization that completely relies on the Internet for its operations. Cyberattacks can lead to an impact on the integrity, confidentiality, and availability of data as well as network resources. Therefore, it is mandatory for all to have a robust network security solution that can protect […]

What is MSTP – Multiple Spanning Tree Protocol?
Introduction Networks are becoming more complex and demanding as the number of devices and applications increases. In order to ensure efficient communication, network engineers must utilize protocols that can handle Vlans, redundancy, and load balancing. One protocol that serves this purpose is MSTP. It is an extension of the Spanning tree protocol, which assists in […]
What are the Different Types of IP Address?
Introduction The Internet has changed the way we communicate, access information, and share data. With the help of the Internet, one can connect with people as well as devices all over the world, regardless of physical distance or location. But the question that arises now is, how do devices identify each other and communicate? The […]
Objectives of Cyber Security
Introduction As technology advances, so does the reliance of businesses on digital services and networks. We all are either directly or indirectly dependent on the security and integrity of online systems in order to protect personal data as well as business operations. Cybersecurity is of utmost importance nowadays, as we all know that cyberattacks can […]
What is IS-IS Protocol?
Introduction IS-IS is a link-state routing protocol that allows the efficient transmission of data in large and complex networks. Now, many network enthusiasts have heard of the term routing protocol, which is a set of rules and algorithms. Routing protocols are utilized by network devices to determine the best path for sending the data between […]
