Modern virtualized data center need to meet certain requirements to accelerate application deployment to support
the new network architecture
. Spine-Leaf network architecture optimizes for the traditional three-tier structure,
significant
ly reducing the loss of information transmission. It is mature technology and has been widely deployed.
It provides a simple
, flexible, and stable network, with good scalability and fast convergence characteristics.
FS N-Series switches support Spine and Leaf architecture, as shown in Figure 4-1 and Figure 4-2.
