传输网络

A South African information technology company on Wednesday proved it was faster for them to transmit data with a carrier pigeon than to send it using Telkom, the country's leading internet service provider.

由于当地网络传输速度太慢，南非首都约翰内斯堡一家信息技术公司改用信鸽帮其传送数据卡，结果证明，信鸽的传送速度果然比网络要快。

In this dissertation, the theory of network coding and its application are studied. Several results are obtained.

网络编码的诞生和发展为网络信息传输指明了一个新的研究方向。

Comparing with the traditional media technology, Stream Media technology hasmore convenient and extensive foreground. The development of Steam Mediatechnology has great signality in China which can release the synchronizationeffect of tbe streams of audio and video problems caused by network transmissionand broadcasting controlment. At the same time, it also tries to improve theStream Media service quality of P_Qos based upon network without Qos.

与传统的媒体技术相比，流媒体技术具有更加方便和广泛的应用前景，它的发展在我国具有重要的现实意义，能够大大缓解因现有网络传输、播放控制等引起的音视频同步效果问题，力图能基于现有的无Qos网络提高流媒体的感知服务质量P_QoS。

Thirdly, the new cryptical function of data voice is realized and management method is strengthened by the network information safety soft wear package. It can not be deciphered, even information is revealed. The goal of real network information safety is realized. The customers\' interests and information safety are protected basicly.

第三项MyData网络信息加密技术采用国际首例的加密方式实现了互联网上数据和语音的高度、有效的加密功能，减轻了由于数据加密给互联网带宽增加负担和造成堵塞本身业务数据量传输的本末倒置的现象，并且即使万一数据从网络上泄漏也可以保证偷窃者无法打开或窥测到内部信息，从根本上保护了企业客户的信息安全和利益。

But the bits to bits arbitration of the CAN protocol defines a static priority to messages exchanged. Due to the fact of the lack of timing information for non periodic data transmission, it is impossible to find a static manner to attribute CAN identifiers to exchanged objects so that applications periods limit can be always be satisfied. When one or many network stations send data using the same identifier, at some point, data will differ and generate error. All stations will then back off and retransmit restarting the whole process. In this case, retransmission can lockup the network.

然而， CAN总线采用位仲裁技术，利用信息的标识符域定义了一种静态的优先权，由于非周期数据传输时缺乏时间信息，不可能找到一个静态标识符分配方案永远满足应用程序对时间的要求；当一个或多个网络节点同时发送标识符相同的数据时，如果数据不同，所有节点都要重新发送数据，在这种情况下，网络将阻塞。

With the development of network technology, there have been high-speed network for bulk data transfer.

中文摘要随着网络技术的发展，目前已经出现了用于长距离数据传输的高速网络。

With the continuous development of Internet technology , some considerable attentions have been directed to the integrated control system and network communication system.

在传统的控制系统中加入网络作为通信媒介，使系统的性能有了大的改观，但同时也不可避免的带来以下问题：网络延迟、丢包问题、单包和多包传输问题等，这些问题的存在，不仅会降低系统的控制性能，而且还能引起系统的不稳定。

This paper analyzed data from multiple sources and different structures, concluded three types of info: Login info, Event info, and Packet data info, then created the formation for every type of data; In order to combine future possible new data, IDS using profile and formation string together, create and practice data formation standard algorithm; Because in the collected data, there is info that is redundant or has minor effect on the IDS, this paper discussed the rules of redundant data differentiating and safe data differentiating, Then create data filter rule base; Data collecting system uses distributivity design, collecting module like a black box. we can get data which was filterd and had standard formation, if we created a new model string for new data source. Module work individually; filter data right away at the collecting node.

本文分析了多种来源的、不同结构的数据，将其总结成登录信息、事件信息和网络数据包信息三种类型，并为每种类型的数据设计了固定的格式；为了与将来可能出现的新型数据兼容，采用了配置文件与模式字符串相结合的方法，设计并实现了数据格式标准化算法；由于收集到的数据中存在冗余的信息和对入侵检测影响不大的信息，本文分别讨论了冗余数据辨别规则和安全数据辨别规则，并建立起数据过滤规则库；数据收集系统采用分布式设计，收集器以黑盒形式提供，对新的数据源只需设计一个新的模式字符串，即可得到过滤后的、具有标准格式的数据，各收集器间独立工作；在收集点即对数据进行过滤，只向分析中心报告可疑数据，以减少传输和存储的数据量，降低对网络性能的影响。

It has been proved in practice that it is an inevitable trend to build the remote monitoring system of dredger machinery equipment based on wireless network and do research on marine monitoring system, onshore monitoring system and their interconnection and data transmission according with the development of wireless network and modern shipping technology.

实践证明，构建基于无线网络的挖泥船机械设备远程监测系统，紧跟无线网络技术和现代船舶技术发展的步伐，进行船载监测系统和岸基监测系统及其互联和数据传输的研究，符合船舶监测系统的发展趋势。

The split between the two groups can hardly be papered over.

这两个团体间的分歧难以掩饰。

This approach not only encourages a greater number of responses, but minimizes the likelihood of stale groupthink.

这种做法不仅鼓励了更多的反应，而且减少跟风的可能性。
