Software Defined <strong>Network</strong>ing (<strong>SDN</strong>)<br />
<strong>and</strong> <strong>OpenFlow</strong><br />
• Software Defined <strong>Network</strong>ing (<strong>SDN</strong>)<br />
• <strong>SDN</strong> virtualizes the network infrastructure – the natural step beyond<br />
virtualization of servers <strong>and</strong> storage<br />
• <strong>Virtualization</strong> has appealed to network managers <strong>for</strong> some time;<br />
consequently, <strong>SDN</strong> is a strategy of substantial global interest.<br />
• <strong>OpenFlow</strong><br />
• Has emerged as one of the world’s most popular <strong>SDN</strong> protocols,<br />
particularly among data centers <strong>for</strong> Web 2.0 companies<br />
• One solution <strong>for</strong> the control of cloud computing, storage, <strong>and</strong><br />
networking resources with a single, unified API*<br />
• The Vision<br />
• With a single instruction, the controller can jointly create virtual<br />
machines, <strong>and</strong> reserve computing, networking <strong>and</strong> storage resources<br />
in a virtual slice.<br />
<strong>OpenFlow</strong> is seen as a native interface <strong>for</strong> <strong>SDN</strong><br />
