The Switch is a network device that is used to segment the networks into different …Among fixed-configuration switches, managed switches are designed to deliver the most comprehensive set of features to provide the best application experience, the highest levels of security, the most precise control and management of the network, and the greatest scalability. As a result, managed switches are usually deployed as aggregation/access …

Routers figure out the fastest data path between devices connected on a network, and then send data along these paths. To do this, routers use what's called a "metric value," or preference number. If a router has the choice of two routes to the same location, it will choose the path with the lowest metric. The metrics are stored in a routing table.Definition of vSwitch. A virtual switch is a software program – a logical switching fabric that emulates a switch as a layer-2 network device. A virtual switch ensures the same functions as a regular switch, with the exception of some advanced functionalities. Namely, unlike physical switches, a virtual switch: Does not learn the …
