A complex system is an embodiment of stochastically interacting subsystems through dynamics of vast information exchange (as seen in biological systems). In this context, a digital ecosystem can be regarded as being deeply intertwined with profiles of an IT-centric complex system. Hence, the complexity of evolution of modern telecommunication (telco) business (in terms of service expansion, revenue growth and customer population) can be modeled via digital ecology concepts inasmuch as the growth and survival of underlying IT activity are implicated by interacting subsystems of a cyberspace. This paper offers an algorithmic model that describes the infrastructure growth of telco service as a complex system evolution projected in the framework of digital ecology. Relevant ontology and computational approach are indicated in pseudo-code formats.
