Thus: performance, reliability, and low power consumption as NFR become
altogether a serious challenge. By applying of DCS redundancy (of both types
natural and deliberately introduced), serving a property of reconfigurability these
challenges are resolvable.
The Internet expanded enormously and still growing in terms of data transfer and
various types of data flows, to name a few: emails, voice and video. The referred
applications are not safety critical and not even really hard real-time ones.
Nowadays, computer and networks are considered through so called Quality of
Service (QoS) requiremens and try to develop mechanisms to provide satisfactory
communications for different combination or sub-domains of QoS. This is actually
completely and perfectly wrong. According to various sources, more than four
billions of IP addresses are assigned permanently, this number which is growing
exponentially puts a lot of strain in the internetwork (Internet). These resources
simply must be used and exploited for good and be flexible, not fixed. Thus, a
reconfigurability of DCS should be used with intelligence, smartness, and flexibility
for all mentioned PRE-requirements.
18.2 Reconfigurability of DCS
Modern communication networks are formed using wired or wireless media, using
distinct signal carriers (fiber, copper, and air). Problems arise due to the complexity
of data and its requirements with regards to timely data delivery and integrity over a
very complex interconnected networks (Internet) [8, 9].
Computer networking encompasses all zones of information processing. This
capability makes them faster and technologically sound. Note that, the zones of any
computer architecture or computer system differ semantically in terms of information processing, namely active, passive and interfacing zones. Below is presented a definition for each of these zones [1–5]:
(a) Active zone—this is the zone where the information is transformed and is
known at the moment in the form of CISC (complex instruction set computers),
RISC (reduced instruction set computers), SIMD (single instruction multiple
data), and MIMD (multiple instruction multiple data) [10].
(b) Passive zones—this is zone is known in the form of dynamic and static
memory, such as DDR SDR and flash memory.
(c) Interfacing zone—this zone is in charge of transferring data from one zone to
another.
Interfacing zone for DCS computers becomes overdeveloped complex and inefficient. Problems we are facing today in terms of networking are caused by the fact
that historically computers technology was not considering potential work within
the DCS framework.
