Quote of Note: G. Keith Cambron
"New networks are born with a simplicity that gives them a natural advantage to serve the changing nature of traffic. To achieve unification and meet new traffic demands, designers, often with different objectives, begin to make changes to expand the base technology, and thereby increase the complexity of the new network. As each change is made, the network begins to be weighed down by its own success. Every design choice removes a degree of freedom, solving an immediate problem but eliminating potential solutions to other problems that lie in the future. Then, once again, the nature of traffic changes, and the entropy of the network makes it brittle and incapable of flexing to meet the new end. The ageing next-generation network is recast as a legacy network, only suited to old traffic types."

I read with interest excellent article by Cambron. Having worked over 30 years in telecom I fully understand the evolutionary forces that shape technology. It simply implies 'limitation of design' that is not uncommon from chaos / complexity theory.
