“…This has been called the communications ‘capacity crunch’, and as we have seen, the approach of such incidents heralds not a collapse of communications infrastructure, but an opportunity for the introduction of revolutionary new technologies. Many new technologies may be considered, including signal processing [ 11 ] and new fibre optic waveguides [ 34 ], but the majority of industry insiders predict that it is likely that commercial pressures will dictate that the next dominant communication technology will be based on a re-introduction of space-division multiplexing [ 28 ], initially as parallel systems, but eventually, including direct spatial coding [ 35 ] and superchannels [ 36 ], and an optimization of the use of resources, including switching (or routing) of signals [ 17 , 18 ].…”

“…The increasing diversity and intricacy of communication services results in a highly complex network that is difficult to reconfigure on short time scales in order to meet changing demand patterns. Current research is focusing on open source network management tools to facilitate greater flexibility in network resource sharing, and in radical new network designs combining previously separate functions [16][17][18]]. -Software.…”

This issue of Philosophical Transactions of the Royal Society, Part A represents a summary of the recent discussion meeting ‘Communication networks beyond the capacity crunch’. The purpose of the meeting was to establish the nature of the capacity crunch, estimate the time scales associated with it and to begin to find solutions to enable continued growth in a post-crunch era. The meeting confirmed that, in addition to a capacity shortage within a single optical fibre, many other ‘crunches’ are foreseen in the field of communications, both societal and technical. Technical crunches identified included the nonlinear Shannon limit, wireless spectrum, distribution of 5G signals (front haul and back haul), while societal influences included net neutrality, creative content generation and distribution and latency, and finally energy and cost. The meeting concluded with the observation that these many crunches are genuine and may influence our future use of technology, but encouragingly noted that research and business practice are already moving to alleviate many of the negative consequences.
