A broadcast storm or broadcast radiation is the accumulation of broadcast and multicast traffic on a computer network. Extreme amounts of broadcast traffic constitute a broadcast storm . It can consume sufficient network resources so as to render the network unable to transport normal traffic. [ 1 ]
In the case of broadcast packets over a switching loop, the situation may develop into a broadcast storm. In a very simple example, a switch with three ports A, B, and C has a normal node connected to port A while ports B and C are connected to each other in a loop. All ports have the same link speed and run in full duplex mode. Now, when a ...
When broadcasting over vehicular ad hoc networks, the original 1-persistence and p-persistence strategies often cause the broadcast storm problem. [citation needed] To improve performance, engineers developed three modified techniques: weighted p-persistence, slotted 1-persistence, and slotted p-persistence.
Broadcast traffic is reduced and VXLAN tunnel endpoints (VTEPs) reply to the caller directly. VXLAN can handle BUM in two ways: Multicast and Head End Replication . Multicast is the most common approach, and each VXLAN network identifier (VNI) is mapped to a single multicast group, while each multicast group may map to one or more VNIs.
To avoid the problems associated with redundant links in a switched LAN, STP is implemented on switches to monitor the network topology. Every link between switches, and in particular redundant links, are catalogued. The spanning-tree algorithm then blocks forwarding on redundant links by setting up one preferred link between switches in the LAN.
This is a common problem on networks with many hosts. [1] Less common is the artificial flooding of address tables in a MAC flooding attack. Another common cause is a host with an ARP cache timeout longer than the timeout of the forwarding information base (FIB) in a switch—the switch forgets which port connects to the target before the host ...
