Initial SDN control plane proposals focused on a centralized solution, where a single control entity has a global view of the network. While this simplifies the implementation of the control logic, it has scalability limitations as the size and dynamics of the network increase.

This mode can be compared with typical routing table entries today, where all static entries are installed ahead of time. Following this, no request is sent to the controller since all incoming flows will find a matching entry. A major advantage in proactive mode is that all packets are forwarded in line rate (considering all flow table entries in TCAM) and no delay is added. In the reactive mode, entries are populated on demand. If a packet arrives without a corresponding match rule in the flow table, the SDN agent sends a request to the controller for further instruction it the reactive mode. The controller examines the SDN agent requests and provides instructions, installing a rule in the flow table for the corresponding packet if necessary. The hybrid mode uses the low-latency proactive forwarding mode for a portion of traffic while relying on the flexibility of reactive mode processing for the remaining traffic. </p> <div class="mw-heading mw-heading2"><h2 id="Applications">Applications</h2></div> <div class="mw-heading mw-heading3"><h3 id="SDMN">SDMN</h3></div> <p><a href="/wiki/Software-defined_mobile_network" title="Software-defined mobile network">Software-defined mobile networking</a> (SDMN)<sup id="cite_ref-MobileFlow_47-0" class="reference"><a href="#cite_note-MobileFlow-47"><span class="cite-bracket">[</span>47<span class="cite-bracket">]</span></a></sup><sup id="cite_ref-48" class="reference"><a href="#cite_note-48"><span class="cite-bracket">[</span>48<span class="cite-bracket">]</span></a></sup> is an approach to the design of mobile networks where all protocol-specific features are implemented in software, maximizing the use of generic and commodity hardware and software in both the <a href="/wiki/Core_network" class="mw-redirect" title="Core network">core network</a> and <a href="/wiki/Radio_access_network" title="Radio access network">radio access network</a>.<sup id="cite_ref-49" class="reference"><a href="#cite_note-49"><span class="cite-bracket">[</span>49<span class="cite-bracket">]</span></a></sup> It is proposed as an extension of SDN paradigm to incorporate <a href="/wiki/Mobile_network" class="mw-redirect" title="Mobile network">mobile network</a> specific functionalities.<sup id="cite_ref-50" class="reference"><a href="#cite_note-50"><span class="cite-bracket">[</span>50<span class="cite-bracket">]</span></a></sup> Since 3GPP Rel.14, a Control User Plane Separation was introduced in the Mobile Core Network architectures with the <a href="/wiki/PFCP" title="PFCP">PFCP</a> protocol. </p> <div class="mw-heading mw-heading3"><h3 id="SD-WAN">SD-WAN</h3></div> <p>An <a href="/wiki/SD-WAN" title="SD-WAN">SD-WAN</a> is a WAN managed using the principles of software-defined networking.<sup id="cite_ref-51" class="reference"><a href="#cite_note-51"><span class="cite-bracket">[</span>51<span class="cite-bracket">]</span></a></sup> The main driver of SD-WAN is to lower WAN costs using more affordable and commercially available leased lines, as an alternative or partial replacement of more expensive <a href="/wiki/MPLS" class="mw-redirect" title="MPLS">MPLS</a> lines.

If an anomaly is detected, the application instructs the controller how to reprogram the data plane in order to mitigate it. </p><p>Another kind of security application leverages the SDN controller by implementing some moving target defense (MTD) algorithms. MTD algorithms are typically used to make any attack on a given system or network more difficult than usual by periodically hiding or changing key properties of that system or network. In traditional networks, implementing MTD algorithms is not a trivial task since it is difficult to build a central authority able of determining - for each part of the system to be protected - which key properties are hidden or changed. In an SDN network, such tasks become more straightforward thanks to the centrality of the controller. One application can for example periodically assign virtual IPs to hosts within the network, and the mapping virtual IP/real IP is then performed by the controller.<sup id="cite_ref-jafarian2012openflow_63-0" class="reference"><a href="#cite_note-jafarian2012openflow-63"><span class="cite-bracket">[</span>63<span class="cite-bracket">]</span></a></sup> Another application can simulate some fake opened/closed/filtered ports on random hosts in the network in order to add significant noise during reconnaissance phase (e.g. scanning) performed by an attacker.<sup id="cite_ref-kampanakissdn_64-0" class="reference"><a href="#cite_note-kampanakissdn-64"><span class="cite-bracket">[</span>64<span class="cite-bracket">]</span></a></sup> </p><p>Additional value regarding security in SDN enabled networks can also be gained using FlowVisor<sup id="cite_ref-sherwood2009flowvisor_65-0" class="reference"><a href="#cite_note-sherwood2009flowvisor-65"><span class="cite-bracket">[</span>65<span class="cite-bracket">]</span></a></sup> and FlowChecker<sup id="cite_ref-al2010flowchecker_66-0" class="reference"><a href="#cite_note-al2010flowchecker-66"><span class="cite-bracket">[</span>66<span class="cite-bracket">]</span></a></sup> respectively.
