OSPF (Open Shortest Path First) works by allowing routers within an autonomous system (AS) to exchange routing information using link-state advertisements (LSAs). Here’s how OSPF operates: Routers running OSPF discover their neighbors and establish adjacencies by exchanging Hello packets. They then exchange LSAs to build and maintain a link-state database (LSDB), which contains information about … Read more
LDAP (Lightweight Directory Access Protocol) is a protocol used to access and manage directory information services. It provides a standardized way of querying and updating information stored in directories, which are hierarchical databases used for storing user credentials, organizational data, and other information. LDAP works by allowing clients to connect to LDAP servers, send queries … Read more
HTTPS (Hypertext Transfer Protocol Secure) is used to secure communication over the internet by encrypting data transmitted between a web browser and a web server. It ensures that sensitive information, such as login credentials, payment details, and personal information, remains private and protected from eavesdropping and tampering during transmission. HTTPS is essential for maintaining the … Read more
The NAS network refers to a storage system connected to a network that allows multiple users and devices to access and share data from a centralized location. NAS on a network is a device that provides dedicated file storage services to other devices on the network. It is designed to store and retrieve data efficiently, … Read more
OSPF, or Open Shortest Path First, is a robust link-state routing protocol used in IP networks to determine the best paths for routing IP packets based on various metrics such as link cost, bandwidth, and delay. It operates by routers exchanging information about their directly connected links through link-state advertisements (LSAs). OSPF routers build and … Read more
Syslog is a protocol used for computer logging and messaging across a network. It facilitates the collection and transmission of log messages from various devices, applications, and systems to a centralized syslog server or collector. Syslog enables administrators to monitor and manage system events, errors, and notifications in real-time, aiding in troubleshooting, performance monitoring, and … Read more
The NIC portal refers to the online platform provided by the National Informatics Centre (NIC) that offers various digital services, information, and resources to government departments, citizens, and businesses in India. The work of NIC includes developing and managing IT infrastructure, providing e-governance solutions, and offering consultancy services to government organizations. NIC supports the implementation … Read more
The BGP (Border Gateway Protocol) protocol algorithm is based on a path vector routing algorithm. Unlike traditional link-state or distance vector algorithms used in interior gateway protocols, BGP operates by exchanging routing information containing network reachability information along with path attributes. This allows BGP to make routing decisions based on policies, path attributes, and AS … Read more
The difference between FTP (File Transfer Protocol) and SMB (Server Message Block) is that FTP is primarily used for transferring files between a client and a server over a network, while SMB is used for sharing files, printers, and other resources over a local network. An advantage of SMB over FTP is that SMB supports … Read more
MPLS (Multiprotocol Label Switching) architecture is a method used in telecommunications networks to efficiently direct data packets through a network. It operates between Layer 2 (data link layer) and Layer 3 (network layer) of the OSI model, enabling faster packet forwarding by using labels to designate paths instead of traditional IP routing tables. MPLS architecture … Read more
