6 and what about Open Dayight Basic Definitions What Is Software Defined Network (SDN)? What Is OpenFlow? 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 Note: SDN is not mandatory for network programmability nor automation Source: Open protocol that specifies interactions between decoupled control and data planes Note: OF is not mandatory for SDN Note: North-bound Controller APIs are vendor-specific What is OpenStack? What is Overlay Network? Opensource software for building public and private Clouds; includes Compute (Nova), Networking (Quantum) and Storage (Swift) services. Note: Applicable to SDN and non-sdn networks Source: Overlay network is created on existing network infrastructure (physical and/or virtual) using a network protocol. Examples of overlay network protocol are: GRE, VPLS, OTV, LISP and VXLAN Note: Applicable to SDN and non-sdn networks 2012 Cisco and/or its affiliates. All rights reserved. Cisco Confidential 6
