Spine-Leaf Architecture

Spine-Leaf Architecture is a two-layer architecture. This architecture has two layers i.e The spine layer and the Leaf layer. The Spine layer and Leaf layer are connected in the full mesh topology. This architecture overcomes the limitations of three-layer hierarchical architecture. Every leaf switch is connected to a spine switch in a full mesh topology. The leaf layer contains the access switches that connects to the servers and provide a connection for end users. The spine layer is called the backbone of the network as it interconnects all the leaf switches.

Spine Switches and Leaf Switches:

Spine switches are connected with all the leaf switches in mesh topology while the leaf switches are connected to the server and connect end users. Spine switches handle layer 3 network traffic whereas leaf switches can handle both layer 2 and layer 3 network traffic. Traditional three-tier architecture has three layers and spine-leaf architecture has two layers. In the traditional three-tier architecture, the east-west traffic is more than the north-south traffic while in spine-leaf architecture east-west traffic flows from server to server within the same data center. Access switches directly connect to the server in spine-leaf architecture. Spine-leaf architecture distribution switches provide redundant connections to access switches. Spine leaf architecture provides fast data transfer between the spine switches and leaf switches....
