Поддерживаю использование в первом предложении Present Perfect. Как вариант можно рассмотреть:
Lately it has become a necessity to consider a heterogeneous network (telecommunications, data units, etc) as a distributing system of partners with different economic interests.

Здесь хорошо: To provide the correct functioning of such systems it must be guaranteed that the presence of such interests will not cause a safety problem.

Дальше можно так:

Или:
