We describe steps required for realizing QoS for the metro Ethernet services, including classification of Customer-VLAN (C-VLAN) traffic, relevant traffic contract specifications per C-VLAN at the User to Network Interface (UNI), appropriate buffer management and scheduling of the queues at the nodes, and admission control and traffic engineering geared towards multipoint services. General func...

Currently telecommunication networks consist of heterogeneous networks, therefore controlling and managing the traffic in these networks will be complex tasks and difficult. Network management activities for these diverse networks require gathering and analyzing huge amount of data from the network. Then based on the activities involved in the network, decisions must be made at different times,...

Traffic modeling and classification finds importance in many areas such as bandwidth management, traffic analysis, traffic prediction, network planning, Quality of Service provisioning and anomalous traffic detection. Network traffic exhibits some statistically invariant properties. Earlier works show that it is possible to identify traffic based on its statistical characteristics. In this pape...

Analyzing short-interval-traffic behaviors is important for network performance management to realize high quality multimedia applications. However, it is difficult to measure short-interval-traffic volumes because there are complications in collecting short-interval-traffic data from routers. An example is a heavy load on routers or inaccurate measurement by the short-polling interval; it even...

Internet traffic classification plays important roles in numerous areas such as network management, traffic engineering, QoS provisioning etc. Prior traffic analysis is an essential requirement for existing classification schemes to classify unknown traffic. To overcome the drawback of the previous classification scheme to meet the requirements of the network activities, we propose online self-...

A novel network architecture based on the IEEE 802.6 metropolitan area networks (MAN) is proposed to integrate the wireless and wired segments of a regional enterprise network (REN) within a city. This architecture functions like a distributed switch for all types of services, reducing traffic congestion by sharing the high capacity link dynamically and facilitating signaling, mobility manageme...

The following essay aims at the description of direct and indirect control mechanisms within the scope of real-time collective traffic control measures. A general system archtitecture of traffic control systems on motorways is presented, including the traffic data detection infrastructure, outstations to preprocess the detected impulses and to control the variable message signs (VMS), subcenter...

This paper considers the effect of active speed management on traffic-induced emissions. In particular, the traffic emissions caused by acceleration and deceleration of vehicles are modelled based on an instantaneous emission model integrated with a microscopic traffic simulation model. The emission model is based on empirical measurements which relate vehicle emission to the type, the instanta...
