Software Defined Networking

What is it all about?

What is SDN? 

Software-defined networking (SDN) is an approach to computer networking that allows network administrators to  manage network services through abstraction of higher-level functionality.

This is done by decoupling the system that makes decisions about where traffic is sent (the control plane) from the underlying systems that forward traffic to the selected destination (the data plane).

Imagine SDN as a very big chassis based switch, which all the Leaf / Spine switches in your network are its Line Cards.
A highly available controller plays the role of Management / Supervisor in SDN. It tells each switch how to forward packets. 

A Big Switch

Big Cloud Fabric

Leaf Spine Clos Fabric for Data Centers 

Big Cloud Fabric™ is the industry’s first data center fabric built using whitebox or britebox switches and SDN controller technology. Embracing hyperscale data center design principles, Big Cloud Fabric solution enables rapid innovation, ease of provisioning and management, while reducing overall costs, making it ideal for current and next generation data centers. 

Big Cloud Fabric is designed from the ground up to satisfy the requirements of physical, virtual, containerized, or a combination of such workloads. Some of the typical OpenStack or VMware data center workloads include NFV, High Performance Computing, Big Data and Software Defined Storage deployments.

Available In Two Editions

P Fabric Edition: a leaf and spine physical Clos fabric controlled by the Big Cloud Fabric SDN controller

P+V Fabric Edition: a leaf, spine and virtual switch fabric controlled by the Big Cloud Fabric SDN controller
