CEWC What Is Software Defined Network (SDN)? “…In the SDN architecture, the control and data planes are decoupled, network intelligence and state are logically centralized, and the underlying network infrastructure is abstracted from the applications…” Source: What is OpenStack? Opensource software for building public and private Clouds; includes Compute (Nova), Networking (Quantum) and Storage (Swift) services. Source: What is Overlay Network? Overlay network is created on existing network infrastructure (physical and/or virtual) using a network protocol. Examples of overlay network protocol are: MPLS, LISP, OTV and VXLAN What Is OpenFlow? “…open standard that enables researchers to run experimental protocols in campus networks. Provides standard hook for researchers to run experiments, without exposing internal working of vendor devices…” Source:

CEWC Cisco continues to pursue broader strategy (Cisco ONE), which includes SDN -Programmatic device APIs -Network overlay virtualization -Network functional abstractions (controller & openflow for SDN) Cisco’s portfolio already includes several key components of an SDN solution OpenFlow is a protocol, not an architecture OpenFlow primarily define a protocol for packet forwarding OpenFlow is not complete for production (e.g. lacks: high availability, security, L3-forwarding model, management infrastructure, testing and certification framework, hybrid deployment capability) Migration to SDN will be evolutionary Cisco will take a use-case driven approach that draws on several key elements of Cisco's product and technology portfolio Cisco will in the near term engage with specific customers on OpenFlow as a prototype technology
