In computer networking, a unicast flood occurs when a switch receives a unicast frame and the switch does not know that the addressee is on any particular switch port. Since the switch has no information regarding which port, if any, the addressee might be reached through, it forwards the frame through all ports aside from the one through which the frame was received.
Security features to prevent ARP spoofing or IP address spoofing in some cases may also perform additional MAC address filtering on unicast packets, however this is an implementation-dependent side-effect. Additional security measures are sometimes applied along with the above to prevent normal unicast flooding for unknown MAC addresses. [5]
In the case of unknown-unicast traffic, a security issue may arise. To prevent flooding unknown-unicast traffic across the switch, it is possible to configure the network equipment to divert unknown-unicast traffic to specific trunk interfaces in order to split broadcast coming from different VLANs or to use specific trunk interfaces for ...

In computer networking, telecommunication and information theory, broadcasting is a method of transferring a message to all recipients simultaneously. Broadcasting can be performed as a high-level operation in a program, for example, broadcasting in Message Passing Interface, or it may be a low-level networking operation, for example broadcasting on Ethernet.

In 1956, Pomona constructed a curved 200-foot-long (61 m), 5-foot-tall (1.5 m) cinder block wall along a portion of the northern edge of its campus as a flood barrier. [ 57 ] [ 58 ] In the early 1970s, students began painting messages on the wall, and Pomona recognized it as a free speech wall in 1975 after the message "Free Angela" was painted ...
