Point-to-Point Protocol (PPP) Phase Diagram
Point-to-Point Protocol (PPP) is a data link layer protocol that enables direct communication between two network nodes. The PPP phase diagram illustrates the six distinct phases that occur during connection establishment, maintenance, and termination. Understanding this diagram is crucial for network professionals as it provides insight into how PPP operates within the OSI model and facilitates multiprotocol data transmission in various networking environments. PPP Phase Diagram Overview PPP Phase Diagram Dead ...
Read MoreWhat is Client-Server Architecture in Computer Network?
In Client-Server Architecture, a specific computer designated as a server provides various services to other computers known as clients. The server acts as a service provider, while the client acts as a service requester. When a client requests information from the server, the server processes the request and responds with the appropriate data or service. Client-Server Architecture Client 1 Client 2 Server Provides ...
Read MoreSSH Port Forwarding
SSH Port Forwarding is one of the most powerful and versatile features of Secure Shell (SSH). It enables users to securely access remote resources over an encrypted channel by forwarding TCP/IP traffic through a secure tunnel. SSH Port Forwarding, also known as SSH tunneling, is a technique that allows users to create a secure connection between their local computer and a remote server. It enables users to securely access remote resources, such as databases, web pages, or other network services that are not directly accessible from their local computer. How SSH Port Forwarding Works SSH (Secure Shell) ...
Read MoreTypes and Uses of Backbone Networks
A backbone network is the central infrastructure component that interconnects multiple networks and provides a high-capacity pathway for data transmission between them. It serves as the primary conduit connecting different local area networks (LANs) within buildings, campuses, or across larger geographical areas to form wide area networks (WANs) or metropolitan area networks (MANs). The backbone network acts as a data superhighway, utilizing various transmission media including optical fiber, copper cables, and wireless technologies such as microwave links and satellite connections. A key characteristic of backbone networks is that their capacity must exceed that of the individual networks they support ...
Read MoreWhat is the difference between WDM and DWDM?
First, let us learn about Wavelength Division Multiplexing (WDM) and then explore its key variant, Dense Wavelength Division Multiplexing (DWDM), to understand their differences and applications. What is WDM? Wavelength Division Multiplexing (WDM) is a technology that combines multiple optical signals of different wavelengths (colors) into a single composite signal for transmission over optical fiber channels. WDM works by using prisms or optical components to multiplex several light waves from different sources, then transmit them simultaneously over the same fiber. The primary application of WDM is in SONET networks where multiple optical fiber lines are multiplexed and ...
Read MoreError-Detecting Codes - Checksums
When bits are transmitted over the computer network, they are subject to get corrupted due to interference and network problems. The corrupted bits lead to spurious data being received by the receiver and are called errors. Error detection techniques are responsible for checking whether any error has occurred in the frame that has been transmitted via network. They do not determine the number of error bits or the type of error, but simply detect the presence of corruption. For error detection, the sender needs to send some additional redundant bits along with the data bits. The receiver performs ...
Read MoreWhat is RSVP (Resource Reservation Protocol)?
RSVP (Resource Reservation Protocol) is a transport layer protocol used to reserve network resources and ensure Quality of Service (QoS) for Internet applications. It operates over Internet Protocol (IP) and uniquely initiates resource reservations from the receiver's end, making it a receiver-oriented signaling protocol. RSVP enables applications to request specific network performance guarantees such as bandwidth, delay, and jitter control. This makes it particularly valuable for real-time applications like video conferencing, VoIP, and streaming media that require consistent network performance. Key Features Receiver-oriented signaling − The receiver initiates and maintains resource reservations, not the sender. ...
Read MoreCloud Radio Access Network (C-RAN)
Cloud Radio Access Network (C-RAN) is a next-generation network architecture that aims to improve the performance, scalability, and cost-effectiveness of wireless networks. In traditional cellular networks, the baseband processing functions are performed by individual base stations, known as Remote Radio Heads (RRHs). C-RAN centralizes these functions into a cloud-based data center, known as the Baseband Unit (BBU) pool. This allows for greater flexibility, as the BBUs can be shared among multiple RRHs, and enables the use of more advanced signal processing techniques. C-RAN Architecture Overview ...
Read MoreThe DNS Name Space
The DNS name space is the complete set of all domain names organized in a hierarchical tree structure within the Domain Name System (DNS). This hierarchical organization enables efficient name resolution and scalable management of internet resources. The DNS namespace starts with a root domain at the top and branches down through top-level domains (TLDs) like .com, .net, and .org, followed by second-level domains and subdomains. Each domain name corresponds to resource records containing information such as IP addresses, mail servers, and other network services. DNS Namespace Hierarchy ...
Read MoreWhat is LAN (Local Area Network) in Computer Network?
A Local Area Network (LAN) is a computer network that connects devices within a limited geographical area, typically spanning a single building, office, or campus. LANs are privately owned networks that enable local connectivity and resource sharing among connected devices. LANs are commonly used in homes, offices, schools, and small businesses to connect personal computers, printers, servers, and other network devices. They facilitate efficient data transfer and resource sharing within the local environment. Local Area Network (LAN) Structure Switch/Hub ...
