  • A New FTTP Technology——Active Ethernet
    Optical Fiber & Electric Cable and Their Applications, 2005
    Co-Authors: Liu Min
    Abstract:

    A new hot FTTP choice besides PON, Active Ethernet which best combines Ethernet with IP technology is introduced. After analyzing their network architecture, we compare in detail these two technologies from several aspects: transmission distance, cost, bandwidth, flexibility, reliability, maintenance, and so on. Finally, a conclusion is given that Active Ethernet is superior to PON in many terms and should be paid attentions by carriers.

  • Real-Time Communication Services for Distributed Computing over Switched Ethernet
    , 2004
    Co-Authors: Xing Fan
    Abstract:

    In modern and future parallel and distributed processing, a large part of computation overhead comes from communication. This can be minimized if the network protocol offers the user services that are aimed at specific types of communication used in these applications. Other important properties of distributed processing applications are time-deterministic latency and guarantees to meet deadlines. Moreover, an important trend is to implement distributed real-time applications on top of standard Ethernet based networks. Therefore, in this thesis, we focus on developing and analyzing how to efficiently support real-time communication services for distributed computing applications over switched Ethernet. The network architecture currently assumed is a switched Ethernet network with only one switch. The work has resulted in proposed Switched Ethernet networks that offer additional features for parallel and distributed real-time processing. An Active Ethernet switch concept is proposed to provide efficient support for different user services, including many-to-many communication and other group communication services with high traffic volumes of short messages. Meanwhile, the real-time support for these special communication patterns is addressed by incorporating deadline-based scheduling in the switch and the end nodes. Moreover, this thesis addresses real-time services by proposing an alternative solution. In this proposal, the Earliest Deadline First (EDF) algorithm is only used in the source nodes to support real-time traffic with a guaranteed bit rate and end-to-end worst-case delay bound. The thesis also reports a feasibility analysis for hard real-time traffic, which also produces figures on the minimum buffer sizes in the switch to be able to guarantee real-time demands. Meanwhile, differentiation of heterogeneous traffic is considered in the proposed system by placing traffic into several priority classes with distinctly different QoS levels. The performance of the proposed methods is evaluated in simulations and calculations. It is shown that the different Ethernet extensions, in many cases, are efficient choices for distributed computing systems.

  • A Techno-Economic Study for Active Ethernet FTTH Deployments
    , 2008
    Co-Authors: Siamak Azodolmolky, Ioannis Tomkos
    Abstract:

    FTTH is recognized as the choice for true broadband access and major implementations of the technology begin to approach. The main drivers of FTTH are bandwidth demanding applications. Among various architectures and technologies of FTTH, home run Active Ethernet FTTH is an interesting technology. However, the main design issue related to FTTH deployments is the high level of CAPEX. In order to justify the FTTH deployments, service providers and network planners require a tool to assist them in selecting an optimized deployment strategy and network design. Lack of modeling tools to perform high level FTTH network planning is the main motivation behind this paper. In this work we present result of a study based on a configurable and customizable techno-economic model, which assist network planners and decision makers to have a high-level picture of Ethernet FTTH deployment. The model captures both the technical and economical aspects of the Ethernet FTTH networks and provides key business performance indicators. The results of a case study for an Ethernet FTTH deployment in a capital city are presented.
