You may have heard about the Access Control List or ACL. It is used to control permissions to a computer system or network, but do you know what is Access control list? As we know, the Internet is a network of networks, and routers play a vital role in having connectivity between different networks. Routers […]

In networking, as we know, switches are used to create networks, while routers are used to connect different networks. By default, switches forward both broadcast and multicast out of every port but not the originating one. However, if you require to divide a single broadcast domain into smaller ones with security in some networks, then […]

Before learning about FHRP (First Hop Redundancy Protocol), a network engineer must understand why redundancy is even required in networking. Why Redundancy? Redundancy plays a vital role in networking. Network redundancy assures business continuity by avoiding failure of the network. By keeping operations running all the time, it boosts productivity. To have a dependable network, […]

Enterprise networks must offer dependable and quantifiable services to enable the transmission of delay-sensitive data, voice, and video. So, QoS is employed by enterprises to fulfil the traffic demands of sensitive applications, such as real-time voice and video, and to stop the quality from degrading as a result of packet loss, delay, and jitter.
