    This paper proposes the forwarding of IPv6 packets using label switching techniques, with the same advantages of the multiprotocol label switching (MPLS) architecture. The paper proposes the mapping of all MPLS header fields into the IPv6 header, raising several advantages like the simplicity of the model and the decrease of overhead. This mapping is called IP next generation label switching - or ... View full abstract»

    The paper proposes a QoS mapping method for VoIP communications in real network environments. To take total account of the effects of several QoS-related parameters, we use a self-organizing neural network, which can map high-dimensional data into simple geometric relationships on a low-dimensional display. For training the self-organizing neural network, we measure several QoS-related parameters,... View full abstract»

    Video and LAN traffic can be modeled as self-similar processes, whereas Internet traffic can be modeled by multifractal processes. The Hurst parameter is a measure of the self-similarity of a process. The objective of this work is to use this characteristic of Internet traffic in order to allow future video on demand service providers (VDSPs) to optimize their bandwidth utilization and consequentl...

    The quality of the audio in IP telephony is significantly influenced by various factors, such as type of encoder, distance, delay variation, rate and distribution of packet loss, type of error concealment, and others. Hence, the performance of any IP telephony system is highly dependent on understanding the contribution of these factors to audio quality, and their impact on adaptive transport mech...

    Quality of service based value-added services in IP networks necessitate the use of traffic engineering. The latter relies typically on monitoring data for both offline, proactive and dynamic, reactive solutions. A monitoring system should be scalable in terms of network size, speed and number of customers subscribed to value-added services. The article investigates the requirements of scalable mo...

    Offering telematics services to end-users involves inter-domain real-time service provisioning; it therefore can also involve inter-domain real-time service accounting. Recognizing the increasing complexity of accounting services due to the dynamic service usage behavior of end-users, the paper addresses, first, a way to decompose end-to-end service into accountable service components, and second,...

    Very little work has been carried out so far in the area of operation and maintenance (OAM) schemes for optical bursts switched (OBS) networks. We continue to discuss OAM issues for OBS networks. The spectral and temporal de-coupling of data and control in an OBS network calls for special OAM attention. In this paper, OAM procedures, functions and sessions based on specific network and node archit... View full abstract»

    Multicast is a natural enabler for carrying high bandwidth multimedia broadcasts and seminars on IP networks. Despite the increased need for IP multicast, its commercial deployment has not been widespread. The lack of appropriate network management tools for IP multicast has proven to be a major barrier in its deployment. In this article, we survey the currently available multicast management tool...

    We propose a congestion control algorithm, referred to as upstream resource management propagation (URMP) algorithm, for label-switched optical burst switching to provide congestion control in a GMPLS control-plane infrastructure. The algorithm controls the transmission control between the congested node and the ingress edge routers. The congested node transmits a control message upstream for the ... View full abstract»

    Future IP networks need to carry multimedia services with diverse quality of service (QoS) requirements. To sustain the contracted QoS needs not only to commit network resources, but also to monitor and control QoS adaptively. Locating the network segment that affects QoS negatively is crucial for controlling resources. The paper analyzes the current QoS distributed monitoring scheme and defines a... View full abstract»

    Middleboxes, such as packet filtering firewalls or network address translators (NATs), are an obstacle to the dynamic setup of connections required by many applications in today's Internet, for example IP telephony. The problem can be solved if the application obtains a means for configuring middleboxes dynamically. The paper discusses the design of the simple middlebox configuration (SIMCO) proto...

    This paper presents a model-based approach to diagnose performance and communication faults in local area networks (LANs). The diagnostic is based on the idea that if the system has an approximate model of the network, and knows how IP packages travels in the network, it can reason about the causes of alarms. A set of subsystems was developed, to gather the network information, to construct the mo... View full abstract»

    Computer networks need to be managed using network management platforms to minimize failure effects. The network management systems can automatically create maps of a network to help administrators to monitor this network. However, such maps represent only a logical layer of the network (e.g. IP-layer). There is no functionality in the management platforms to automatically create maps of a physica...

    We discuss the concept of a custom screens builder for network elements management. The builder dynamically creates custom screens on the basis of screen templates. We propose XML-based templates employing a few simple but flexible constructs that significantly augment the SMI (structure of management information) and MIB (management information base) definitions. We also describe implementation d... View full abstract»

    IEEE 802.11 WLANs (wireless LAN) are proliferating at an unprecedented rate. To realize the benefits of localized, high-bandwidth WLANs along with highly available, low bit-rate overlay WWANs (wireless WAN), mobile hosts (MH), such as laptops and PDAs, are being equipped with multiple wireless network interface cards (NIC). This enables a mobile user to switch to a WLAN, if available, and then swi... View full abstract»
