The lowest of the three SONA layers provides the point of interconnection between various IT resources. The Networked Infrastructure Layer encompasses servers, storage, and network-connected endpoints. These resources exist in various volumes and geographies throughout the network. The Networked Infrastructure Layer provides the common transport and connectivity between required services such as CPU cycles, storage, memory, and I/O. Rather than using individual, dedicated (or mission-specific) resources, SONA sees these elements simply as resource pools.
The SONA model reaches out across network geographies to pull all resources into a single, logical entity. The architecture includes specifications on the construction of all of these geographies, including the campus, branch, data center, WAN/MAN, and teleworkers. Each is addressed individually in the SONA model as each is crucial to the creation of an IIN capable of providing a common user experience anytime, anywhere and from any device.
As you might expect, TCP/IP becomes the pervasive network protocol and the network provides the shared transport for all business application traffic. This is known as convergence. This allows the network infrastructure to become service ready, allowing the offloading of application functions away from application resources through service integration.
