VRRP is an open standard protocol, which is employed to produce redundancy during a network. it's a network layer protocol (protocol number-112). The number of routers (group members) during an exceedingly group acts as a virtual logical router which is in a position to be the default gateway of all the local hosts. If one router goes down, one in every of the choice group members can occur for the responsibilities for forwarding the traffic. Some important terms associated with VRRP : virtual IP address : An IP address is assigned as a virtual IP address from the local subnet which is configured as a default gateway for all the local hosts. Virtual MAC address : A virtual MAC address is automatically generated by taking the last 8 bytes because the VRRP group number in hexadecimal. In VRRP, Mac address used is 0000.5e00.01xx. Here, xx is that the VRRP group number in hexadecimal. Master router : one in every of the VRRP group member is elected as master router which takes up the ...

Quality of Service (QoS)  is a set of technologies that work on a network to guarantee its ability to dependably run high-priority applications and traffic under limited network capacity. QoS technologies accomplish this by providing differentiated handling and capacity allocation to specific flows in network traffic. This enables the network administrator to assign the order in which packets are handled, and the amount of bandwidth afforded to that application or traffic flow. Aslo Quality of Service (QoS) across IP networks is becoming an increasingly important aspect of today's enterprise IT infrastructure. Not only is QoS necessary for voice and video streaming over the network, it's also an important factor in supporting the growing Internet of Things (IoT). In this article, I'll explain why QoS is important, how it works, and describe some use-case scenarios to show how it can benefit your end users' experience. Measurements of concern to QoS are bandwidth (throug...
