从管理的5大基本要素出发,从网络层面、业务层面、管理层面,对IP网络流量管理模型进行探讨。在网络层面,需提供分级服务;业务层面要根据不同的业务需求,划分业务的QoS等级,实现网络质量服务差异化,限制DDoS等异常流量;在管理层面上应适当限制、合理引导,流量计费和带宽出租相结合。整体的流量管理才能让IP网络的性能表现达到最佳。 相似文献

The design and measured performances of a broadband branch-line coupler are presented. The broadband coupler was designed by using a four-section branch line topology with a structure of the defected ground. Such a structure can make the impedance of the microstrip line much larger than that without defected structure, even using a normal PCB process. More than 231 Omega was easily achieved by such a defected structure. The measured performance of the broadband coupler agrees well with the results from simulation 相似文献

1 宽带接入非常美妙 从技术上说,宽带(Broadband)是指在同一传输介质上,可以利用不同的频道进行多重(并行)传输,并且速率在1.54Mbps以上。因此与传统的Internet接入技术相比,宽带接入技术最大的优势就是其带宽大大拓展。如传统使用的模拟Modem接入网络时,速率最高不超过56kbps,而使用宽带接入设备如10/100M自适应网卡时传输速率可达10Mbps,是模拟Modem的180倍!宽带接入将为更平滑的视频图像、更为清晰逼真的声音处理和更为迅速的网站搜索服务提供坚 相似文献

This didactic paper presents the major approaches to the design of correcting networks which optimize the transfer of power in linear circuits. The analytic theory initiated by Bode, Fano and Youla furnishes precise information on the realizability of givencharacteristics of power transfer between a resistive source and a complex load, but the determination of characteristics which are both realizable and nearly optimal remains extremely difficult. On the other hand the so-called real frequency technique developed by one of the authors considers from the outset the optimization problem and gives excellent results with reasonable computational effort. Moreover it is applicable to other problems, e.g. the design of fet broadband amplifiers, when the reactive device is specified empirically. 相似文献

The Internet's phenomenal growth has created the potential for a ubiquitously connected society. This potential has been slow in coming, however, in part because the majority of today's home users connect to the Internet over slow analog telephone lines. Slow modems and congestion at popular Web sites have further contributed to the “World Wide Wait”. Broadband access (connections at data rates of 250 kbps or more) has long promised a solution, but until recently, technology has been unable to deliver these higher speeds at a reasonable cost. Despite this and other problems, affordable broadband access is just around the corner. What this means for users is a change that will profoundly affect Web access and the existing communication (telephone) and media (TV and radio) industries. The main drivers for narrowband's transition to broadband are new applications that will soon be available. In addition, a slew of new Internet access devices and supporting products will become available in the next few years 相似文献
