Yin and Yang of Modern Networks: Software Defined Networks vs. 100Gbps and Sub-millisecond Latency

There are two driving forces in modern networks: Software Defined Networking and increasing bandwidth and performance demands. DevOps aims are at the core of Software Defined Networking. The aim is the transformation of networks into applications or API(s). This requires density through virtualization. This drives bandwidth requirements that are increasing faster than Moore’s Law. Demanding latency requirements are more stringent with more video and voice in large datacenters for cloud applications require carrier-level throughput. These are at odds.
Software defined networking is based on overlay networks. Some of the most popular in production are OTV, GRE, CAPWAP, and OpenFlow. These are driven by needs to create flexibility in packetized networks. However, any kind of overlay is virtualization. Which is something that does not run on bare metal and thus is slower. Old administrators know that the user is affected more by network performance than computer performance. By the nature of networks they affect a larger audience when there is trouble. Slowing down networks in our world is a non-starter. So how, in an increasingly software defined world, would an administrator maintain speed?
Hardware acceleration must be integrated using native Openflow and standard software overlays as native protocols. These will be used to traffic engineer the network into low-latency exa-scale API platforms.
