The authors of [19] study a joint optimization model that is geographically distributed and interconnected using an optical network.
In this paper, a hierarchical content distribution architecture for the telecom cloud is investigated: core DCs placed in geographically distributed locations, are interconnected through permanent "per content provider" (CP) virtual network topologies (CP-VNT); additionally, metro DCs need to be interconnected with the core DCs.
To date there has been only a few wide area SDN deployments mostly for controlling networks interconnecting geographically distributed data centers (Google's B4 is one example), but these heavily rely on aggregation of flows, which comes at the cost of a coarse control granularity.
The Argentine Power Interconnection System (APIS or SADI for its acronym in spanish) is composed by a diverse set of power plants, interconnected by a geographically extensive and weakly meshed network of 500 and 220 kV, to meet demand (131 TWh for year 2014), largely located in Buenos Aires (50%).
A key feature of the proposed algorithm is that it exploits coarse grained parallelism and the components running in parallel need not synchronize after every iteration, thus the algorithm lends itself to be implemented on a geographically dispersed set of processing elements interconnected through a network.
A geographically distributed web server (GDWS) system consists of multiple server nodes interconnected by a metropolitan area network (MAN) or a wide area network (WAN).
Geographically-interconnected PMSAs are combined to form CMSAs, of which there are 18 in the United States.
These studies have been for locations with geographically dispersed wind farms, some degree of dispatchable energy or hydropower with storage capacity, demand management, and interconnected to a large grid area enabling the export of electricity when needed.
Everything is interconnected.
Everything is now interconnected".
