Software Defined Networking
Software Defined Networking (SDN) is an approach to networking in which network control is
decoupled from the underlying physical infrastructure and is directly programmable
SDN CONTROL
SOFTWARE
Control / Mgmt Protocols
APIs
Applications that communicate with
the SDN-enabled network via open APIs
Software-based networking functions that
control and manage the network
Network transport forwarding plane that may
consist of physical and virtual network functions

Reliability
• AT&T control layer augments existing distributed
MPLS architecture that offers fast restoration and
resiliency
• SDN controllers are geographically distributed and
redundant
• SDN controllers reside inside virtual machines and
can be replicated in case of failure in near real time
Security
• SDN controllers centralize security management
• Virtualization enables multi-vendor, real-time
provisioning of security functionality
• Streamlined security processes: reduced path
cycles, faster incident response, and improved
DDOS resilience
