An Improved Real-time Traffic Flow Monitoring Scheme

Real-time traffic flow monitoring is essential to the management of multimedia networks and services. This paper presents an improved scheme and its CORBA-based implementation based on our previous work [1]. This scheme can be used to simultaneously locate relevant traffic monitors along the path of a certain real-time flow and retrieve traffic information from them. By consolidating traffic information from these monitors embedded in different network segments, it is easy to derive quality of service (QoS) related parameters, such as delay jitter and loss ratio of this flow in different network segments. The improvement of the new scheme over the scheme in [1] is that the new scheme can be performed in multiple network management domains.
