Examples of Load Models for Different Traffic Sourcesrealistic source of loads, but their application is often restricted e.g. in long simulation runs when the repetition of the limited trace should be avoided, or in analytical studies which require a mathematical description of the traffic.

Engaging

Architecture of the Unified Load Generatordel which is described by means of a corresponding User Behavior Automaton as introduced in Chapter 3. The execution of the UBA in the modelling domain results in a sequence of initially abstract requests which are generated according to the specifications in the UBA.

Load Generation at Network Layer Service Interfacese UniLoG adapter for IPv4 network service interface (further referred to as UniLoG.IPv4) and discuss the most important details of its implementation. Performance characteristics of the implemented adapter are of particular interest for the experimenter and we present the results of the corresponding performance evaluation tests carried out by us.

Estimation of QoS Parameters for RTP/TCP Video Streaming in WLANsend-to-end delays of TCP packets and result in violation of the real-time requirements (e.g., in missing play-out deadlines) of the particular video frames [WKST08]. The conventional wisdom for media streaming is to use UDP, rather than TCP, as the transport protocol.
