A spine-leaf architecture is an increasingly popular data center network topology that consists of two switching layers—a spine and leaf. The leaf layer consists of access switches that aggregate traffic from servers—typically affixed top of rack (ToR) or end of rack (EoR)—and connect directly into the spine or network core.

The backbone of this network architecture is called the spine, from which each leaf is connected to further extend network resources. The network can grow uniformly by simply adding more spine or leaf switches, and without changing the network performance. The spine section of the network grows horizontally which restricts the layers of the ...
