Routers are the backbone of connecting networks and communicating between them. If you wonder exactly how data is transmitted through these routers, this article we'll give you a pretty good idea.
There are two fundamental approaches to moving data through a network of links and switches: circuit switching and packet switching. In circuit-switched networks, the resources needed along a path (buffets, link transmission rate) to provide for communication between the end systems are reserved for the duration of the communication session between the end-systems.

These are some important information of Switch and Hubs, two important equipments in a network. Switch has replaced the bridge in the modern network, which is replacing routers in many instances as well. A switch is a box with multiple cable jacks in it that looks a lot like a hub. Some manufacturers have hubs and switches of various sizes that are all but identical in appearance. The difference between a hub and a switch is that while a hub forwards every incoming packet out via all ports, a switch forwards each incoming packet only to the port that offers access to the destination system.

Routing is a relay system by which packets are forwarded from one device to another. Each device in the network as well as the network itself has a logical address so it can be identified and reached individually or as part of a larger group of devices. For a router to act as an effective relay device, it must be able to understand the logical topology of the network and to communicate with its neighboring devices. Related Article Tags: , , , , ,
