Functional dependencies and points of intersection between the mechanisms for providing guaranteed QoS

Contemporary technology progress increase the requirements towards the communicational environment – performance, opportunities for transfer of multimedia streams in a real time, reliability etc. Two leading end goals emerge – scalability and reliability of the network solutions, according to which the data traffic in the computer networks is designed and developed. Furthermore, increased possibilities for achieving optimized network parameters as delay and bandwidth are requested. Existing architectures reflect the differences in the approaches for the design of the packet-router interaction scheme in order to achieve a guaranteed level of quality of service (QoS). This paper discusses the task for defining of the roles and the functional dependencies between the routers and the packets as a common problem in the flow of creation and improvement of QoS architectures.
