Today, cloud and virtualization are increasingly pushing the need to abolish hierarchical construct of network to a simpler and dynamic flat service-oriented infrastructure. And, it is for good reason: create non-blocking architecture, reduce cost and complexity and improve latency and manageability of the network. As network flattened, tiered notion of aggregation blends away to form two distinct elements of network: Edge and Core. While Edge extend service-oriented infrastructure to network entry point, network core multiplexes zeta bytes of data transport making it easier to traverse multiple operators in a unique mesh architecture.
