Configuration of QoS in IP network using Cisco devices
Brož, Kamil ; Šporik, Jan (referee) ; Růčka, Lukáš (advisor)
This bachelor's thesis is divided into two main sections. The first, theoretical section, deals with parameters and requirements of modern real-time applications. This project analyses the particular means of providing QoS. It deals with access in a form of integrated services (IntServ) and with newer access in a form of differentiated services (DiffServ). The chapter covering the Integrated services describes the very basic principles of the problematics. Differentiated services and used algorithms are discussed in detail. The second, practical section, describes the capabilities of Cisco devices and their particular implementation in two designed network scenarios including traffic measurement and user experience tests.
Quality of service assurance in IP networks
Kupčiha, Lukáš ; Skořepa, Michal (referee) ; Hošek, Jiří (advisor)
The aim of this work was introducing the options of configuration mechanisms for quality of service (QoS) in basic network products of Cisco company. The characteristics of the techniques for control and management of bandwidth, delay, jitter and packet loss were examined and explained. The attention was then focused mainly on DiffServ mechanism. Its individual functions, such as classification and marking, traffic rate management and its policing and shaping, congestion management queuing and congestion avoidance, are discussed in detail. Further investigation was aimed at the possibility of QoS implementation on Cisco devices. The basic principles and commands for providing the quality of service were then demonstrated by Cisco MQC. The specific terms, such as traffic class definition, policy definition and policy application, were presented and explained. Consequently, the different scenarios of measurement were proposed and a testing network was designed. Influence of FIFO, PQ, CBWFQ and WRED mechanisms on the network traffic was measured. As a result of the work, the optimal mechanism for providing the quality of service was chosen.
