  • the evolution of Transport Network survivability
    IEEE Communications Magazine, 1999
    Co-Authors: Joyce Manchester, P Bonenfant, C Newton
    Abstract:

    The bandwidth explosion ushered in by the popularity of the Internet has spurred the acceleration in the development and deployment of equipment supporting packet-based services. This-coupled with the widespread deployment of dense wavelength-division multiplexed systems in the core Transport Network to satisfy the corresponding increase in capacity demand-has led Network planners to reconsider traditional approaches to Network survivability. Existing architectures for Transport Network survivability were developed based on a ubiquitous circuit-switched/TDM Network paradigm. As tariffed services increasingly migrate from circuit-switched/TDM to packet-switched/DWDM Networks, survivability architectures must also evolve to meet the service requirements of this "new" packet-switched/DWDM Network paradigm. We begin with an overview of existing strategies for providing Transport Network survivability, followed by an analysis of how the architectures for Network survivability may evolve to satisfy the requirements of emerging Networks.

  • Application of the Molecular Algorithm in Public Transport Network Problem
    Computer Science, 2012
    Co-Authors: Dong Yafei
    Abstract:

    Molecular bio-computation is a developing subject with good potentiality.This is a first try to apply a public Transport Network into this field.Based on the analysis of Transport Network problems,we ingeniously transformed the optimized travel problem into a weighted graph issue.Firstly,integrating the self-assembly idea,we built a molecular bio-computational model of it,three factors were involved——the length of the road,congestion coefficient and transfer.Secondly,taking the public Transport Network graph of local area of Xi'an for example,we gave a detailed description in the biochemical operating steps.It shows the feasibility and great superiority for the molecular algorithm applied in the transit Network research.Based on the algorithm,the complexity of the Transport Network problem can be obviously reduced,also the research fields of the molecular bio-computation can be extended.

  • ICC - An agent-manager scheme for the integrated Transport Network management
    1999 IEEE International Conference on Communications (Cat. No. 99CH36311), 1
    Co-Authors: Kyung Hyu Lee
    Abstract:

    The TMN-based approach makes it possible to pursue integrated management technology which makes the Network manager easily recognize the relations between lower speed Transport Network and higher speed Transport Network. The super-high speed Transport Network is to be deployed which connects down to the various tributary Networks. In this paper, an agent-manager scheme for managing effectively the relation of this tributary layered Transport Networks is proposed. The purpose is to propose the server role of the agent for the effective relational management based on the common management information model on Transport Network nodes. Furthermore, the impact of the effectiveness of the integrated management and engineering on this agent-manager design are described.

  • A Model and an Algorithm of Urban Transport Network Capacity
    International Conference on Transportation Engineering 2009, 2009
    Co-Authors: Changzhi Bian, Ziyin Deng
    Abstract:

    This study deals with the problem of urban Transport Network capacity with link capacity constraint. After a thorough review on urban Transport Network capacity modeling, a new bi-level programming model is formulated. In upper level program the Network capacity is maximized. And a logit-based stochastic traffic assignment model with link capacity constraint is adopted in the lower level model. Then a novel algorithm was proposed. The flow-to-capacity ratio is used as the convergence criterion. An example is given and numerical results show the algorithm is potential for practical applications.

  • Urban Transport Network Capacity Considering Level of Service
    ICCTP 2009, 2009
    Co-Authors: Haiwei Wang, Changzhi Bian, Ziyin Deng
    Abstract:

    This study deals with the problem of urban Transport Network capacity under a given level of service. After a thorough review of urban Transport Network capacity modeling and multiple objectivity programming, a multiple objectivity bi-level programming model is formulated, which considers that the Network capacity analysis should link the level of service of a road Network together. In an upper level program is a multiple objectivity model which includes: (i) the maximization of the Network capacity; and (ii) the maximization of the level of service. And a logit-based stochastic traffic assignment model is adopted in the lower level model. Then the goal programming method is proposed. An example is given and numerical results show the algorithm is feasible for practical applications.
