Can Computing Fabrics really operate over the WAN and broadband?
The broadband will constitute an interconnect with which to “loosely couple” cells, clusters of nodes that are local and tightly coupled themselves. This will require predictability of latencies for utmost performance, but that can be achieved through QoS measures debuting over the next 5 years. Systems will not use hardware approaches to tightly couple over broadband connections. It is the essence of fabrics that they utilize both types of couplings, tight and loose, but in a more flexible manner than current networks and clusters.
