A fat tree topology is a type of network layout. It is commonly used in computer networks to handle a large amount of data traffic. The network is built in layers in this topology. They start with smaller nodes (like leaves) that connect to larger nodes (like branches and roots). Each layer adds more capacity to manage data flow, which helps prevent network congestion.
A fat tree topology has more connections at the top layers. They allow data to move smoothly even when there are many users. It is often used in data centers and high-performance computing systems.
Example:
Imagine a school library network. Small computers on each floor are connected to larger servers in the main office. The top layer has stronger connections. It allows many students to access resources without slowing down the network.
