The article looks into the current state of the art of dynamic routing protocols with respect to their possibilities to react to changes in the Quality of Service when selecting the best route towards a destination network. New options that could leverage information about the ever changing QoS parameters for data communication are analysed and a Cisco Performance Routing solution is described more in detail. The practical part of this work focuses on a design and implementation of a test bed that provides a scalable laboratory architecture to manipulate QoS parameters of different data communications flowing through it. The test bed is used in various use cases that were used to evaluate Cisco Performance Routing optimization capabilities in different scenarios.

Individuals, organizations and society have dealt with various kinds of data for hundreds of years. But only in recent years that arose into a new challenge, which is Big Data. This topic is popular in various fields, because it can provide new insights on working system, social engineering, even management and much more. Big Data is thus becoming a technologically attractive field in both science and industry. The paper provides an overview to the nature of Big Data, its challenges, but also some insights into how it may be used in working infrastructure of any information related company. Several real life examples provided in this paper will give a better insight into how it works and how it can inspire more ideas on how to leverage existing data resources to create new knowledge.
