Spline and leaf network diagram. Overlay networks allow the separation and specialization of device functions based on where a device is being used in the network. There are however some disadvantages which is why the spine leaf architecture is gaining popularity. Use pdf export for high quality prints and svg export for large sharp images or embed your diagrams anywhere with the creately viewer. I got the below reference diagram from vmware document for nsx design with cisco nexus switches.

Creately diagrams can be exported and added to word ppt powerpoint excel visio or any other document. Benefits of a network virtualization overlay include the following. Leaf spine is a two layer network topology composed of leaf switches and spine switches. However when we talk about leaf and spine network topology it is a 2 tier network topology the topology is composed of 1 leaf switches connected to the end devices e g.

1 in the diagram there is separate pod for compute management edge. We used this model for over a decade so network engineers are familiar with this design and the protocols we use. 10g 40g 100g uplinks from leaf to spine for a leaf spine network the uplinks from leaf to the spine are typically 10g or 40g and can migrate over time from a starting point of 10g n x 10g to become 40g n x 40g. The traditional three tier network topology includes access switches aggregation routers sometimes referred to as the distribution layer and core routers.

The topology is composed of leaf switches to which servers and storage connect and spine switches to which leaf switches connect. An ideal scenario always has the uplinks operating at a faster speed than downlinks in order to ensure there isn t any. Leaf spine is a two layer data center network topology that s useful for data centers that experience more east west network traffic than north south traffic. 2 the spine switch is 9500 the leaf switch is 93xx series.

A leaf spine architecture is a more efficient network topology than the traditional 3 tier network. When the network grows we can easily add more distribution or access layer switches. A spine leaf architecture is an increasingly popular data center network topology that consists of two switching layers a spine and leaf. A spine and leaf network topology also known as leaf spine network is a two tier design that is intended to overcome the limitations of the traditional three tier network architecture and provide improved performance.

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.
