为解决数据在传输和信道转发中,光纤网络易因节点同台扰动的影响而被攻击,导致网络异常,为提高光纤网络安全性,提出基于异常图谱特征和嵌入式ARM的光纤网络异常监测系统设计。该系统硬件由组件控制模块、数据调度模块、检测滤波模块和人机交互模块共同构成,通过对存储器调度的设计实现网络监测程度的加载和自适应数据的读取。基于异常图谱特征提取技术构建光纤网络异常数据传输模型,结合链路均衡配置方法进行光纤网络传输信道均衡设计,提取光纤网络传输数据的异常图谱特征,采用模糊特征聚类方法进行异常波束聚能处理,根据异常信息的输出指向差异性实现异常监测。实验表明,采用该系统进行光纤网络异常监测时误码率低至0. 031,对异常信息的检测准确性高达97. 6%。 相似文献

Passive optical networks are a prominent broadband access solution to tackle the "last mile" bottleneck in telecommunications infrastructure. Data transmission over standardized PONs is divided into time slots. Toward the end of PON performance improvement, a critical issue relies on resource management in the upstream transmission from multiple optical network units (ONUs) to the optical line terminal (OLT). This includes resource negotiation between the OLT and the associated ONUs, transmission scheduling, and bandwidth allocation. This article provides an overview of the resource management issues along with the state-of-the-art schemes over time-division multiplexed PONs (TDM-PONs). We categorize the schemes in the literature based on their features, and compare their pros and cons. Moreover, we introduce a unified state space model under which all TDM-PON resource management schemes can be evaluated and analyzed for their system level characteristics. Research directions are also highlighted for future studies. 相似文献

The key technologies required for the development of optical transport networks, namely, optical fiber transmission and digital transport, which includes transmission signal multiplexing, transport nodes, and network operation functions, are highlighted. The trends in transport technology, the impact of synchronous digital hierarchy (SDH) and asynchronous transfer mode (ATM), the role of telecommunications management networks, and network integrity enhancement techniques are elucidated. It is demonstrated that these technologies have brought about a great change in transport network design and performance. Further innovations are required to fully realize a high-performance computer communication network, a cost-effective nationwide B-ISDN, and local networks for video distribution. These include the realization of an optical access transport network and the extension of trunk network capabilities which will be possible with optical path layer technologies 相似文献

Diverging optical network requirements are driving innovations in optical components in multiple directions. The telecommunications network core needs new components to increase capacity while reducing cost: optics that enable faster line rates, more wavelengths per fiber, and longer spacing between repeaters. Metro networks need components to handle complex traffic patterns. A desire for network reconfigurability in both long-haul and metro segments drives demand for switches, but also for other associated components to condition signals after switching. The next generation of optical transport equipment will rely on new types of optical components to perform functions that do not yet exist in the network 相似文献

Lightpaths on demand: a Web-services-based management system 总被引:3,自引:0,他引:3
User-controlled optical networks play a key role in supporting electronic transfer of the enormous volumes of data generated in emerging e-science experiments. The ability of users to manage their own resources enables provisioning of bandwidth-guaranteed tunnels on demand without the costs associated with conventional managed services offered by network providers. However, building high-performance user-controlled networks has only become feasible in the last few years, as trends in the telecommunications industry have made it possible for users to purchase installed optical fiber and light it using their own premises equipment. Consequently, suitable network management technologies have not yet evolved. In particular, there is presently no means for users to easily provision bandwidth-guaranteed tunnels across multiple independent management domains. In this article we present a user-controlled lightpath management system that addresses this problem. We begin by reviewing the high-level functionality of the system. Then we examine the software architecture. Finally, we discuss design challenges faced while building the system and propose future extensions. 相似文献
