SCOP: a tool used to configure heartbeat intervals / heartbeat message parameters. In reality, there is no heartbeat or beacon -- or packets, frames etc. The reality is that the internet is based on cyclic time intervals that serve as opportunities in time to do / not do computational tasks. If and when the world realizes the role of time in context with the internet, use of time cycles will (finally) become the common building block to build our world in an equitable, reliable, CONSISTENT manner.  Not acknowledging the internet as metering, measuring time cycles leads to endless hype cycles: HYPE CYCLE: The Hype Cycle is a branded graphical tool developed and used by IT research and advisory firm Gartner for representing the maturity, adoption and social application of specific technologies. The Hype Cycle has five 5 stages: 
1Technology TriggerA potential technology breakthrough kicks things off. Early proof-of-concept stories and media interest trigger significant publicity. Often no usable products exist and commercial viability is unproven.
2Peak of Inflated ExpectationsEarly publicity produces a number of success stories—often accompanied by scores of failures. Some companies take action; many do not.
3Trough of DisillusionmentInterest wanes as experiments and implementations fail to deliver. Producers of the technology shake out or fail. Investments continue only if the surviving providers improve their products to the satisfaction of early adopters.
4Slope of EnlightenmentMore instances of how the technology can benefit the enterprise start to crystallize and become more widely understood. Second- and third-generation products appear from technology providers. More enterprises fund pilots; conservative companies remain cautious.
5Plateau of ProductivityMainstream adoption starts to take off. Criteria for assessing provider viability are more clearly defined. The technology’s broad market applicability and relevance are clearly paying off.
