Technical Foundation of the Software Defined Fabric™

An industrialized software solution for networking white boxes. It is designed for hyperscale and distributed data centers and targeted to clients in the data center operator, telco, enterprise, cloud, and gaming industries. As a programmable data center fabric, the solution offers integrated routing and switching and enables developers to develop new code to drive innovation and clients to add new services and features in-house. In addition, its programmability avoids vendor lock-in and eliminates the need to wait for silicon upgrades.

The flexible fabric architecture presents an adaptable, high-performance, low latency multi-datacenter fabric, specifically designed to satisfy the current and future challenges of increasing network workload demands at scale. Software Defined Fabric™ can run several virtual data-centers with different network services, thus fulfilling the vision of a truly customizable Software Defined Network (SDN) environment.

Software Defined Fabric™ features advanced self-forming and self-discovery capabilities, zero touch provisioning (ZTP) of the virtual networking and virtual components, and automated software upgrades, thus minimizing human intervention and errors while saving time and effort. Network provisioning time is reduced from several days to minutes and is automatically updated during runtime.

Software Defined Fabric™ has been designed to virtualize the data center. A physical data center can be partitioned into multiple independent and fully isolated virtual data centers (vDCs). Each vDC operates with its own Virtual Fabric (vFabric), which can host millions of IPv4 or IPv6 based tenant networks. Additional compute and storage resources can be dynamically assigned or removed from a vDC through the associated vFabric, thus creating a flexible and elastic pool of network resources suitable for network slicing.

The need for expensive physical appliances is eliminated, and new emerging requirements can be met by leveraging low cost networking white boxes. Software Defined Fabric™ is a pre-tested and certified software solution for networking white boxes from Accton and Delta.
