Hi @abody

Do you mean "Unicast Packet Flooding in Switched Networks"?

if so,

Problem Definition

LAN switches use forwarding tables (Layer 2 (L2) tables, Content Addressable Memory (CAM) tables) to direct traffic to specific ports based on the VLAN number and the destination MAC address of the frame. When there is no entry corresponding to the frame's destination MAC address in the incoming VLAN, the (unicast) frame will be sent to all forwarding ports within the respective VLAN, which causes flooding.

Limited flooding is part of the normal switching process. There are situations, however, when continuous flooding can cause adverse performance effects on the network. This document explains what issues can arise due to flooding, and the most common reasons why certain traffic might constantly be flooded.

Hi, friend!
As for the Deep Flooding mentioned by you, I consulted the documents and did not explain it. Can you tell me what protocol this is, or what function it is?

Hi!

Flooding is a simple routing technique in computer networks where a source or node sends packets through every outgoing link.

Flooding, which is similar to broadcasting, occurs when source packets (without routing data) are transmitted to all attached network nodes. Because flooding uses every path in the network, the shortest path is also used. The flooding algorithm is easy to implement.

I searched for this information on google, but my intention is to simplify the concept for me Explain Deep Flooding in switching?-4666783-1

The official explanation for flooding is that the source node wants to send a piece of data to the destination node. The source node first transmits a copy of the data to each of its neighbors over the network, and each neighbor node transmits the data to its own other than the one that sent the data. This continues until the data is transferred to the destination node or the time to live (TTL) set for the data is 0. The simple explanation is that packets are flooded from the source node to the
