The China National Financial Network(CNFN) is an open system architecture-based data communications network, supporting the national level financial application systems.
Of the various IP solutions, IP over ATM, IP over SDH/Sonet, and IP over WDM/ Optical are the competitive focus of the future IP trans-port technologies and multimedia communications network technologies. The practical information network structure at present is IP( + ATM) over Opti-cal( + SDH).
在各种 IP技术方案中,IP over ATM、IP over SDH/SONET、IPover WDM/Optical等技术是未来 IP传送技术、多媒体通信网络技术的竞争焦点,当前较为实际的信息网络结构的演变是将ATM和SDH技术层中的冗余部分取消,将其精华分别集成到IP应用层和光层中,形成IP(+ATM)over Optical(+SDH)的技术模型。
The paper introliuce the history of management of Telecommunication Network and analyses the problem of current management of Network and the trend and new technology in the field.
Because of the development of telecommunication network and the present condition of PCM which is used in dispatching applications widely,according to the analysis of the channel link protection function of FMX12 equipment and the introduction of typical application schemes,FMX12 can switch two channels automatically,therefore it improves the reliability of applications,and this method is useful in practice.
To model communication functions, the model LogGP is used which allows taking into consideration the specific character of the communication network of the distributed computer system.
The vulnerability of communication network measures the resistance of the network to the disruption of operation after the failure of certain stations or communication links.
We show how these criteria can be applied to prove the existence of a stationary operation regime in a dynamic access communication network with conflict warning.
Computational results are reported for three different problem instances, one of which is a real-life problem faced by SONOFON, a Danish communications network operator.
We introduce a novel scheme to ensure the continuous and synchronous delivery of distributed stored multimedia streams across a communications network.
This will form an innovative communications network among students and between students and faculty, a development with the potential for impact beyond this program.
The ant algorithms are especially efficient for online optimization of processes in distributed nonstationary systems (for example, telecommunication network routing).
Ground fissures and subsidence have caused extensive damage in structures and the utility networks (roads, railroad line, Larisa NATO airport, telecommunication network) in the plain of Thessaly, central Greece, in the last 20?years.
The analysis of time-indexed categorical data is important in many fields, e.g., in telecommunication network monitoring, manufacturing process control, ecology, etc.
