Titre / Title: Surveillance de trafic dans les réseaux à haut débit
Abstract : Broadband Integrated Service Digital Network (B_ISDN) is the universal communication network proposed by the ITU_T. It will support different types of traffic (e.g video, voice and data) with different statistical characteristics and Quality of Service (QoS) requirements. Statistical Multiplexing allows different connexions with to share the same network resources in order to achieve high utilization of the network. But this raises new network management problems for the agreement establishment, the traffic policing and the congestion control.
In this report we first give a brief survey on traffic management in B_ISDN. We concider Frame Relay (FR) and Asynchronous Transfer Mode (ATM). We are especially intrested in policing schemes. Then we present comparative study of two basics of policing mechanisms: The Jumping Window and the Leaky Bucket.
By simulation means, we first analyse the behaviour of the two mechanisms versus their own parameters shaping. Then we analyse their behaviour upon different source burstiness levels.
