Rightsizing refers to the process of restructuring or reorganizing done by an organization by reducing the workforce, restructuring the upper-level management, or cost-cutting. The prime objective is to rightly mold the organization to maximize its profit. Hypothetically, the term rightsizing intended that the organizations should rightly...
A broadcast storm occurs when a network system is overwhelmed by continuous multicast or broadcast traffic. When different nodes are sending/broadcasting data over a network link, and the other network devices are rebroadcasting the data back to the network link in response, this will eventually cause the whole network to melt down and lead to the failure of network communication.
There are many reasons a broadcast storm occurs, including poor technology, low port rate switches and improper network configurations.
Although computer networks and network devices are very intelligent and efficient, networks and network devices sometimes fail to provide 100% efficiency. The broadcast storm is one of the major deficiencies in computer network systems.
For example, let's suppose there is a small LAN network consisting of three switches (Switch A, Switch B and Switch C), and three network segments (Segment A, Segment B and Segment C). Two nodes are attached within this network. Node A is attached to Segment B, while Node B is directly attached to Switch A. Now, if Node B wants to transmit a data packet to Node A, then traffic will be broadcast from Switch A over to Segment C; if this fails, then Switch A will also broadcast traffic over Segment A. Because Node A neither attaches to Segment C, nor Segment A, these switches would further create a flood to Segment B. If neither device/switch has learned the Node A address, then traffic will be sent back to Switch A. Hence, all devices/switches will keep sending and resending the traffic, eventually resulting in a flood loop or broadcast loop. The final result is that the network will melt down, causing failure in all network links, which is referred to as a broadcast storm.
The following elements play an active role in the creation of a broadcast storm:
