There has always been a disconnect between applications and network architects where developers write applications to run over a network as long as there is connectivity. In addition, service-oriented architecture (SOA) based applications call for greater application componentization, which increases messaging between application components, resulting in the network having a direct impact on application performance. In essence, application owners, developers and application standard bodies assume that networks are borderless as the industry is organized around the OSI model where knowledge and skills at one layer, e.g., the network is not necessarily taken into account at another layer, i.e., the application. Therefore, the normal state of affairs is that network designers have been tasked to optimize applications to improve user experience especially when the application was not written to run over a particular kind of network. This status quo does not scale and needs to be re-thought.
