Course detail

Modern Network Technologies

FEKT-MMOSAcad. year: 2011/2012

The aim of the subject is to introduce recent trends in the fields of modern network technologies especially from the view of control algorithms and mechanisms implemented into communication protocols. The first part of the subject provides sufficient mathematical background from queuing theory. It is followed by a detailed analysis of flow-control methods on the data link layer of the OSI/ISO Reference Model. The next part of the lectures is oriented to the control mechanisms implemented in the TCP transport protocol. The last part deals with the topics of Quality of Service support, from basic principles up to implementation details in mobile and wireless networks.
