Deliberately sending data faster than, or without regard to, the throughput capacity of the network. This causes congestion and data loss. Many audio/video protocols and some UDP based transport mechanisms cause flooding. Even TCP can cause periodic flooding. MTP is specifically designed to avoid flooding the network, thus improving speed and efficiency.
Flooding is a tactic used in the sport of Australian rules football. It involves the coach releasing players in the forward line from their set positions and directing them to the opposition forward area, congesting the area and making it more difficult for the opposition to score. It is commonly deployed to protect a lead, or prevent a rout.
