Why the Best Foundation for SDN is an Enterprise-Wide Automated Core

Software-defined networking offers enterprises significant potential to not only increase efficiency and reduce operational cost, but fundamentally alter the way applications and infrastructure interoperate, consequently improving business agility, innovation and competitive positioning.

While technically SDN can be described as a separation of control and data plane (and many industry players will have us believe that SDN is all about data center automation), the truth is far from it. The key value proposition of SDN lies in the ability to quickly and effectively integrate the programmable (network) edge with applications that support users and business processes.

The “edge,” in this case, is not to be understood as the typical network edge (device) but as the place where the network meets the application, i.e. a hypervisor supporting multiple application VM’s or Docker containers, an edge voice application device (also known as a phone) or devices purpose-built as SDN edge devices.

This edge differentiates the way applications can use and/or interact with the infrastructure. At this programmable edge, the true power of SDN is unleashed.

Building upon a poor enterprise network foundation is ill advisable. As enterprises deploy SDN-based applications, these applications need to enable agile development and reliable and fast deployment, while simultaneously supporting existing enterprise applications.

Avaya’s Fabric Networking Architecture is specifically designed to meet all these requirements through:

    • Providing a fully automated, secure and reliable virtualized core network: The Avaya Fabric Connect core network is a true, modern, core network architecture that is drastically simplified, compared to complex, legacy network technologies.Avaya relies on a single, provider-grade, standard core network protocol: Shortest Path Bridging (SPB).

      Fabric Connect offers customers an automated, zero-touch core network, full network virtualization, supporting up to 16 million service identifiers, sub-second switchovers in case of failures, full topological flexibility and PCI-compliant stealth networking capabilities–a true, enterprise-grade core network designed for maximum reliability and the lowest-possible operational cost.

    • Enabling an automated and flexible edge: Building upon the capabilities of the automated, zero-touch core network, Avaya Fabric Extend enables extensibility over any 3rd-party network.Avaya Fabric Attach enables edge devices, be they switches, wireless access points, hypervisors, cameras or Internet-of-Things devices, to automatically attach to the fabric and connect to the desired virtual service network, thus removing any need for edge pre-provisioning, reducing operational cost and increasing ease of use.
    • Unleashing the power of the open ecosystem: Building upon the automated core and Fabric Attach-enabled edge, open SDN edge devices, such as any Open vSwitch-based device, can automatically and zero-touch attach to the desired virtual service network.Utilizing the open interfaces and open-source tools and controllers, such as Open Daylight, customers can quickly deploy SDN applications in an agile fashion and benefit from innovations from the community at large.

As with many things in life, a solid foundation is the beginning of great things to come. Avaya’s SDN architecture provides the industry’s leading automated enterprise core, and with it, the foundation to SDN success.
