Network Devices Part 1:HUB


Hubs, simple multistation access units, and repeaters are the most basic forwarding devices. These devices aren't very intelligent. In fact, they don't know what a packet is; they see only 1s and 0s. Essentially, these devices forward bits from one port to another. For example, a hub receives a 1 bit in one port and copies this 1 bit to all other ports.

Of course, handling packets in this way can create problems if a device sends a broadcast storm. In this case, the broadcast storm affects all of the devices that are connected to the hub. A switch that offers broadcast throttling capabilities or a router may help you better control network traffic. These more advanced products work at the second layer in the OSI mode.
