In any IT setup, Network Engineer is the key and fundamental resource responsible for setup of network infrastructure on which all the services like Security, voice, wireless, messaging and Internet are made accessible. A network engineer is a technology expert …
Application availability, continuity of service, greater performance of the application – These are the things we would always require from a platform owner while designing the network and answer to this in AWS is called ELB (Elastic load balancing). This …
The Transmission Control Protocol/Internet Protocol (TCP/IP) is a network communication protocol that interconnects the network devices into the internet. It provides a communication between the source and the destination. It specifies how data packets should be broken, addressed, routed, transmitted, …
Open Systems Interconnection Model (OSI) refers to a logical and conceptual network model that defines the network communication protocol that is used by open systems to communicates and connect with other network systems. This network model has seven subcomponents. Each …
The transferring of data between two devices is known as Transmission Mode or Communication Mode in Computer Networks. So the Transmission mode basically defines the direction of flow of signal between the connected devices. TYPES OF TRANSMISSION MODES The different …
Generic Routing Encapsulation (GRE) is the IP encapsulation protocol that is used to transport IP packets over the network. Generic routing encapsulation was initially developed by Cisco, but later become industry standard (RFC 1701, RFC 2784, RFC 2890). GRE can …
Address mask is also known as Subnet mask. IP address has the 2 main components among which the one is “Network Address” and other one is “Host address”. The subnet mask or the address mask separate network address with the …
NIC or Network Interface Card is a circuit board or expansion card or a chip, that enables a computer to connect to a network, be it a home network, or the Internet using an Ethernet cable. Initially, network controllers were implemented as expansion …
Torrenting is a P2P (peer-to-peer) file sharing technology used to share files efficiently.This technology relies on a community of decentralized users for file sharing rather than being dependent on traditional single website or source for downloading. A user can download …
VRF (Virtual routing and forwarding) is a technology that allows multiple instances of a routing table to co-exist within the same router at the same time. Overlapping IP addresses can be used without conflicting with each other as the routing …
Leaf-and-spine is a two-layer network topology composed of leaf switches and spine switches. We are all aware of the Cisco’s 3-tier network topology with the following 3 layers – 1)Access Layer 2)Aggregation/Distribution Layer 3)Core layer The Access Layer connects to the end devices (e.g. clients …
iBGP is abbreviation for Internal Border Gateway Protocol. iBGP protocol is used between the routers within the same autonomous system (AS) .iBGP speaking Routers need to form full mesh to maintain full routing information. Full mesh (iBGP neighborship with all Routers in …
Network Switching works at Layer 2 (Data Link Layer) of OSI model. Switching is a process of receiving frame from one incoming port (ingress) and then forwarding it to as desired destination (egress). Switching is of 2 types – Circuit …
