Ethernet is pervasive. This is due in part to its ease of use. Equipment can be added to an Ethernet network with little or no manual configuration. Furthermore, Ethernet is self-healing in the event of equipment failure or removal. However, there are scenarios where a local event can lead to network-wide packet loss and congestion due to slow or faulty reconfiguration of the spanning tree. Moreover, in some cases the packet loss and congestion may persist indefinitely.
