Market
A new Target Operating Model (TOM) which is market
driven (private or public cloud), outsourced, out-tasked or
Orchestration and automated provisioning of virtualised
(and where appropriate physical) infrastructure
Abstraction of physical resources – unified data center
comprising network, compute and storage
Applications, network, servers, storage and operational
silos

Basic Definitions
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: www.opennetworking.org
What is OpenStack?
Opensource software for building public
and private Clouds; includes Compute (Nova),
Networking (Quantum) and Storage (Swift) services.
Source: www.openstack.org
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:
GRE, VPLS, OTV, LISP and VXLAN
What Is OpenFlow?
Open protocol that specifies interactions between
de-coupled control and data planes
Note: OF is not mandatory for SDN
Note: North-bound Controller APIs are vendor-specific
Note: Applicable to SDN and non-SDN networks
Note: Applicable to SDN and non-SDN networks
Note: SDN is not mandatory for network programmability
nor automation
