    While deployment of new network technologies has not been steady over the years, it is useful to take a long-term view of how major new telecommunications infrastructures evolve. Since the beginning of this decade, we have witnessed the emergence of new generations of three major communication networks. This article addresses the market conditions, technology innovations, and services driving the ... View full abstract»

    A likely architecture for the future broadband access network will consist of a trunk-and-branch topology, with very high bandwidth trunks (e.g., 1-10 Gb/s), connected to high-bandwidth drops (or branches) to homes and businesses. A multihop switched Ethernet data transport can be used over this access network. Wang (see Internet QoS: Architectures and Mechanisms for Quality of Service, Morgan Kau... View full abstract»

    WiFi, also known as 802.11b, has become the preferred technology for wireless local area networking in both business and home environments. Even though it was designed primarily for private applications, WiFi is also being deployed in public places to create so-called hotspots, where WiFi-capable users can obtain broadband Internet access. This new domain of application could be the major future m... View full abstract»

    This article describes a practical approach for providing quality of service in the Internet backbone. The approach considers both technical and economic factors. We first present network service provider (NSP) billing models and how NSPs provision their networks. We then analyze causes of QoS-related problems, and describe a practical approach for providing QoS. This approach makes use of good ne... View full abstract»

  • An overview of constraint-based path selection algorithms for QoS routing

    Constraint-based path selection aims at identifying a path that satisfies a set of quality of service (QoS) constraints. In general, this problem is known to be NP-complete, leading to the proposal of many heuristic algorithms. We provide an overview of these algorithms, focusing on restricted shortest path and multi-constrained path algorithms. View full abstract»

  • A new architecture for transmission of MPEG-4 video on MPLS networks

    Due to insufficient network bandwidth on the Internet, multimedia-oriented applications are still not popular. Traffic on the Internet often causes congestion in routers. Therefore, the Internet must overcome these challenges and bottlenecks to provide more multimedia-oriented applications. We study the transmission of MPEG-4-based video traffic in MPLS networks, and propose a better architecture,... View full abstract»

  • QoS in best-effort networks

    The QoS of today's best-effort network does not deliver the performance required for a wide range of interactive and multimedia applications that have demanding delay and bandwidth requirements. We discuss how current research into congestion control has uncovered that best-effort networks, with just a few modifications to the existing equipment, can deliver the performance required for a range of...

  • QoS routing computation with path caching: a framework and network performance

    We present a framework for QoS routing computation with path caching. The framework has three phases to allow different levels of information to be processed at different timescales to effectively meet QoS requirement of a newly arrived flow. Path caching is introduced in the first phase to allow selection and filtering in subsequent phases. We describe several routing schemes that can fit into th... View full abstract»

  • Quality-of-service mechanisms in IP-over-WDM networks

    Classical approaches to QoS provisioning in IP networks are difficult to apply in all-optical networks. This is mainly because there is no optical counterpart to the store-and-forward model that mandates the use of buffers for queuing packets during contention for bandwidth in electronic packet switches. Since plain IP assumes a best effort service model, there is a need to devise mechanisms for Q... View full abstract»

    This article gives an overview of VDSL and summarizes the main system requirements developed by ANSI-T1E1.4, ETSI-TM6, and ITU-T Study Group 15/Question 4 in a coordinated effort. For the time being, both single-carrier modulation and multicarrier modulation schemes have been proposed for standardization. VDSL is an enabling and cost-effective access solution for the last mile of the network over ... View full abstract»
