Data Center Spine-and-Leaf Solution

With east-west traffic growing, operators need low-latency, optimized traffic flows to increase network performance. A spine-leaf
network architecture makes sure that traffic must cross the same number of devices to get to the next destination. This approach
provides load balancing, the overall traffic becomes predictable and IT managers obtain a greater control over the network.

In a spine-and-leaf topology, every leaf switch is connected to the spine switches in a mesh topology. The spine switches are the
backbone of the network and are responsible for interconnecting all leaf switches. Packets are allocated randomly in the entire
network, so traffic is evenly distributed among the top-of-rack switches. If any top-of-rack switch fails, packets are distributed to
other switches for processing

In addition, a spine-leaf architecture provides better scalability. If operators need to expand the capacity to serve more subscribers,
additional switches can easily be added to the topology. This not only increases the total bandwidth, but also reduces the OPEX of
network expansion by optimizing the process of scaling the network.

Edgecore offers cutting-edge solutions, including switch hardware (with choice of different silicon designs) and operating system
SONiC to fully support spine-leaf architecture – from 1G management switching up through 10G and 25G top-of-rack or leaf layers,
and then 100G and 400G for spine or super-spine layers.
