Traffic Type Influence on QoS Network Performance of Streaming Traffic Class

Abstrakt

Feasibility study on QoS routing proved that the traffic type influence the network performance. The performance is defined here as a number of packets serviced by the network. In the paper additional element - buffers lengths used in service system was verified in terms of dependencies with routing performance. We present results obtained by simulation for many simulation scenarios. Analysis was done for two different network topologies and for two traffic types (Poisson and self-similar) and for two traffic classes (streaming and best-effort) as a function of buffer lengths within streaming traffic class and for many proportions between these traffic classes. Analysis was done for two routing algorithms: OSPF and DUMBRA. To generate self-similar traffic multiplexed ON-OFF model was used. Relative measure was used for comparison of network performance for given traffic type. Received results in some cases were hard to comment and difficult to fit into regular pattern which points that the subject is complex and very complicated at the time. One of basic conclusion is that relative difference between these two networks structures and its performance depends on the buffer lengths in the service systems however with some exceptions.
