SDN Market Dynamics
“Higher-layer application
functions will become
integrated with lower layers
of the network, leading to
two-way application
awareness. The network will
be able to adapt to changing
application requirements
efficiently and effectively.
In other words, applications
will be able to dictate what
the network needs to do to
support them.”

  1. First click – however, new challenges have come to light (bigger, faster, etc) Second click – Off main monitor Poor visibility: Need the ability to correlate Complex QoS: how do we simplify? In demo BYOD: UC diff beast (50% email vs 50% voice call example to slide to) 60% poor calls However we have a new set of challenges. After analyzing numerous customer UC deployments of real-time media we have concluded that many poor UC real-time media calls are the cause of the network. It is very difficult for enterprise administrators to gain visibility into when a call goes bad as to what is the root cause of the problem. Without having the ability to correlate a call across a network and understand what network defects were occurring during the call, UC real-time media diagnostics becomes very difficult, timely and difficult QoS is complex and a black art to deploy. Not only do we have various variations layers of QoS (ie 802.1p, WMM, DSCPs, etc) we also have to coordinate all the moving parts including applications, network elements, etc and make them sing together. Even once we get everything just perfect, over time we see configuration drift and eventually we are back to square one. I will be covering more on this in an upcoming slide and our demo BYOD lack the awareness to do the right things for real-time media sessions. The Wi-Fi characteristics for running real-time media is vastly different then running data. We see all kinds of issues with BYODs and mainly because the Wi-Fi drivers lack the knowledge to know when an active voice or video stream is active. Coupled with the fact that there is no way for an application to communicate with the Wi-Fi driver via the OS this becomes even more problematic. We need a way to program a device when a real-time media session is active to do the right things. More on this in a later slide As stated before, many poor calls are the results of network issues. In fact greater then 60% of poor UC end-user QoE is due to the network. We have to move to a better and more cost effective method of making UC and networks work better together
  2. So we took SDN and brain stormed what if an end user application like UC could program the network. What if the application layer that was traditionally relegated to orchestration and virtualization was UC centric also. Since UC real-time media flows or sessions can last from minutes to hours we saw them as long lived flows that were perfect to programing the network. We asked what if we could provide an out-of-band web service that informed the SDN controller of the start and end of a call and if the call was experiencing quality degradation due to network defects such as packet loss, jitter and delay. So we did just that and developed a REST based API and started to work with partners in evolving this vision. We started to work with vendors for all kind of scenarios and wanted to evolve SDN past the data center into Wi-Fi, campus, WAN and even LTE.
