Construct an argument as to why indirect communication may be appropriate in volatile environments. To what extent can this be traced to time uncoupling, space uncoupling or indeed a combination of both?

What will be an ideal response?

Volatile environments are environments where change is anticipated both in terms of the availability of computers and the underlying network. Mobile computing is one example of a highly volatile environment where users may connect and disconnect from the global network and may also experience periods of disconnection or weak connection because of location. Indirect communication is an appropriate strategy for such volatile environments for two key reasons:
Firstly, with the potential for failure, it is useful to have a communication mechanism that does not communicate directly with a given recipient, rather indirectly through an intermediary, providing a level of freedom for the system to replace, update, replicate or migrate the intended receiver (space uncoupling).
Secondly, with the potential for disconnection (of both sender and receiver), it is useful to have a communication mechanism that does not rely on both parties being available at the same time to communicate (time uncoupling).
