Abstract
The recent substantial growing of video and voice traffics in the Internet may cause a great impact on the conception and dimensioning of a network node designed to attend only data traffic. The objective of this paper is to investigate how these traffics can affect the present network which works with FIFO scheduler. For this purpose, a simulation platform consisted of several different kinds of sources, a buffer and a FIFO scheduler was developed in C++ language. Many different scenarios of traffic compositions were simulated for the study of the network node behavior in relation to queue and system times which are important parameters for QoS definition. The results showed that video traffic can impact very strongly all the network infra-structure including the whole congestion of system. The results also showed that voice traffic has less impact on the network but in a mixed operation of traffics, the system cannot guarantee the QoS of voice traffic which needs almost real time treatment. The main conclusion of this paper is that the admission control mechanism and QoS provisioning need to be implemented urgently to cope with the fast growing of video and voice traffics.
