自相似、長(zhǎng)相關(guān)業(yè)務(wù)的生成及TCP擁塞控制的研究 目前,Internet的規(guī)模日益增大,承載的業(yè)務(wù)種類也不斷增加.Internet已給人們的生活和工作帶來(lái)了巨大的利益和影響.21世紀(jì)是通信的世紀(jì),是互連網(wǎng)的世紀(jì).經(jīng)過(guò)20多年的發(fā)展,Internet已經(jīng)在全球取得巨大的成功.該文對(duì)自相似、長(zhǎng)相關(guān)基本理論進(jìn)行了研究,得出了生成自相似、長(zhǎng)相關(guān)業(yè)務(wù)的方法,即通過(guò)重尾分布ON/OFF源的N-Burst模型的聚合業(yè)務(wù)來(lái)生成自相似、長(zhǎng)相關(guān)業(yè)務(wù),使用國(guó)際上比較通用的仿真軟件NS-2來(lái)進(jìn)行仿真.并基于此特征業(yè)務(wù),對(duì)TCP性能進(jìn)行分析.最后對(duì)TCP擁塞控制進(jìn)行改進(jìn),以適合自相似、長(zhǎng)相關(guān)的的網(wǎng)絡(luò)特性,提高網(wǎng)絡(luò)性能.

The XML Toolbox converts MATLAB data types (such as double, char, struct, complex, sparse, logical) of any level of nesting to XML format and vice versa. For example, >> project.name = MyProject >> project.id = 1234 >> project.param.a = 3.1415 >> project.param.b = 42 becomes with str=xml_format(project, off ) "<project> <name>MyProject</name> <id>1234</id> <param> <a>3.1415</a> <b>42</b> </param> </project>" On the other hand, if an XML string XStr is given, this can be converted easily to a MATLAB data type or structure V with the command V=xml_parse(XStr).

AutoBoot is a generic boot loader that automatically locates, loads, and executes object files from multiple types of media. AutoBoot provides a simple, fast, and functional means of loading an OS image while maintaining a small Flash memory footprint. This binary release contains a stand-alone version of AutoBoot for the DbAu1200 development board, designed to replace the YAMON boot loader.

Foundations of Python Network Programming leads readers through every aspect of client and server programming with Python. Python is a new and innovative scripting language. It is set to replace Perl as the programming language of choice for scripters and for serious application developers wanting a feature rich yet simple language to deploy their products in. This book features extensive examples that not only demonstrate important concepts and practices, but also provide a cadre of fully-functional stand-alone programs. Readers can use the examples as the basis and building blocks for their own software

Hibernate: A Developer s Notebook shows you how to use Hibernate to automate persistence: you write natural Java objects and some simple configuration files, and Hibernate automates all the interaction between your objects and the database. You don t even need to know the database is there, and you can change from one database to another simply by changing a few statements in a configuration file. If you ve needed to add a database backend to your application, don t put it off. It s much more fun than it used to be, and Hibernate: A Developer s Notebook shows you why.

usb bulk 傳輸例程。 * The bulkusb driver is a generic function driver, based on the Windows Driver Model (WDM). * Supports Plug and Play(PnP), Power Management(PM), Windows Management Instrumentation (WMI) and the Selective Suspend (SS) features. * This sample is based off the selSusp DDK sample. Please refer the selSusp sample and the DDK docs to understand the handling of PnP, PM, WMI and SS features and implementations. * The USB device used for this sample is a generic Intel I82930 USB evaluation board programmed with a simple loopback test using a 64 KB circular buffer. None of the code in the sample is specific to this controller chip.
