Content Aware Smart Routing

Today's Internet has reached its scalability limits with respect to the number of
participants and performance. Contemporary Internet devices are not just
computers, but also tablets, smart phones and even small devices, like sensors
and actuators. A variety of new technologies is inherent to these Internet
appliances, like IPv6, ZigBee, 6LoWPAN or NFC. From the combination of these
technologies a new paradigm arises, the so called Internet of Things (IoT). The
problem of all these new services is how a service can be addressed. Typically,
a client has to know the exact resource identifier (URI) in order to use a specific
service hosted by a server somewhere in the Internet. This thesis provides a
concept which relaxes the strong binding between service and server by the
use of IPv6 focusing on the addressing of sensors and actuators. A client can
place an unaddressed request to the so called content aware network. A smart
router fetches the request and forwards it to a dedicated server, which is able
to process the request. To this end, the request contains a semantic tag which
is interpretable by participating network nodes. After the initial primary request
is sent to its target server, this server examines the request and performs some
secondary requests in order to set the corresponding actuators or to fetch
current values from sensors. In addition to the correct routing of unaddressed
requests, the content aware network is also able to route unaddressed data
packets sent from sensor/actuator-units. Such a data packet can be sent for
example on the change of a node's internal state. As a proof of concept, an
elementary reference system is implemented which provides a reduced set of
functionalities in order to evaluate the concept with respect to performance,
security and fault tolerance. The network's performance, measured in the
amount of messages, is compared to some theoretical alternative approaches.
In order to preserve security, IPsec is investigated.

Qualitativ hochwertige Softwaretechnik zu produzieren ist unerlässlich, um auf
dem Markt zu bestehen und optimale Kundenzufriedenheit zu erreichen. Für
diese Zielsetzung muss sich die Organisation mit Konzepten des Qualitätsmanagements
und der Optimierung der eigenen Prozesse auseinandersetzen.
Qualitäts- und Projektmanagement dienen als Querschnittinstanzen und Bindemechanismen
zwischen den einzelnen Phasen der klassischen Softwaretechnik.
Anerkannte Standards, Vorgehensweisen und qualitätsorientierte Prozesse
sind gut in neu aufgesetzten Projekten anzuwenden, allerdings führt die
