WINSOCK-UDP
- VC++接收、发布广播信息代码 VC++接收、发布广播信息的程序代码,广播信息其实也就是一个服务器和一个接收机,这里简化为一个服务端和客户端,服务端向外发送信息,客户端自动接收,当然,这里仅实现最基本的单元,扩展空间很大,了解了原理,你就能举一反三,开发出更复杂的消息应用来。-VC++ to receive, publish broadcast code VC++ to receive, publish broadcast the program code, broadcasting inf
Route_Analytics_Crossing_the_Chasm
- 路线分析:即将跨越鸿沟 在90年代初,IT组织开始部署帧中继网络。这些网络的绝大多数,如自动柜员机网络,他们后面,是使用内置一个中心和轮辐设计。这种设计在很大程度上是因为它反映了感觉鉴于当时的一个组织内的信息流是自然从分支机构到总部的设施,然后再返回。-Route Analytics:Poised to Cross the Chasm In the early 1990s, IT organizations began to deploy frame relay networks.
MEF14
- 该规范主要定义了流量管理方面的测试内容(流量管理的相关定义在MEF10),提供承载在EVC之上的流量性能测试规范。实际上,对于基于队列的流量管理,流量整形等QoS相关的测试,MEF14测试套件也是一个非常好的选择。 -The specification defines the traffic management aspects of the major test content (defined in the related flow management MEF10), to provi
IOportFactSheet
- IO端口速查表,用于凌阳单片机编程时对单片机的端口查询。-IO port Fact Sheet for Sunplus programming queries to the microcontroller ports.
2-Internetworking-LAN_2(zslcn)
- 令牌环网络最初是由IBM在20世纪70年代开发的。它现在仍然是IBM的主要局域网络(LAN)技术。相关的IEEE 802.5规范与IBM的令牌环网络几乎是相同的,完全兼容。事实上,IEEE802.5规范仿照IBM令牌环,并不断跟踪IBM的令牌环网开发。术语令牌环网一般通常用来既指IBM的令牌环网,也指IEEE 802.5网络。本文讨论令牌环网和IEEE802.5这两者。-The Token Ring network was originally developed by IBM in the 1
C_-Socket-communications
- 网络套接字(Socket)是基于TCP/IP协议的程序实现协议。实际上,我们所有的网络编 程都是基于Socket而实现的。 -The network socket (Socket) is to achieve an agreement based on the TCP/IP protocol procedures. In fact, all of our network programming are achieved based on Socket.
Linux
- inux是一种自由和开放源码的类Unix操作系统,存在着许多不同的Linux版本,但它们都使用了Linux内核。Linux可安装在各种计算机硬件设备中,比如手机、平板电脑、路由器、视频游戏控制台、台式计算机、大型机和超级计算机。Linux是一个领先的操作系统,世界上运算最快的10台超级计算机运行的都是Linux操作系统。严格来讲,Linux这个词本身只表示Linux内核,但实际上人们已经习惯了用Linux来形容整个基于Linux内核,并且使用GNU 工程各种工具和数据库的操作系统-inux is
2012_WIFI
- 现在利用WIFI无线上网已经成为了众多网友的上网方式,回到家打开笔记本轻松无线在网络畅游,但如果你经常闯南走北,WIFI上网似乎利用的少之又少,因此许多人选择了3G无线上网,但3G的速度和价格实在不太给力,也许在线看个电影,几百元就没了,因此还是找到免费的WIFI比较靠谱,速度快还无限流量,重要的不花钱。目前有很多地方都有免费的WIFI热点信号,但如何找到这些信号成为了漂流在外网友们的难题,那么文章接下来的目的就是要告诉你,到底该如何寻找“热点”?你身边哪里的免费“热点”信号速度快信号好?其实只
linuxthread
- 我们要讨论的是网络中进程之间如何通信?首要解决的问题是如何唯一标识一个进程,否则通信无从谈起!在本地可以通过进程PID来唯一标识一个进程,但是在网络中这是行不通的。其实TCP/IP协议族已经帮我们解决了这个问题,网络层的“ip地址”可以唯一标识网络中的主机,而传输层的“协议+端口”可以唯一标识主机中的应用程序(进程)。这样利用三元组(ip地址,协议,端口)就可以标识网络的进程了,网络中的进程通信就可以利用这个标志与其它进程进行交互。-We have to discuss how communic
asp-to-html
- 初学ASP,程序是能勉强写出来了,但若每进行一次网站页面的改版,所有的源程序都将进行一次移植手术。为此所耗费的人力精力不计其数,甚至一不小心得不偿失、前功尽弃。所以,梦想着那么大段的程序代码变成几个简单的字符代替,这样只要设计好页面把该功能插入就OK了。其实这也简单,只需将实现该功能的程序代码做成子程序,然后主页调用就可以了。-Beginners ASP, procedures can barely write out, but if the site pages once for each r
Resolving-Interference-Problems
- Interference is annoying and often frustrating, especially when the problems are intermittent or when it seems that a problem has been solved, only to have it return later. Efforts to correct interference problems are also often complicated by the fa
Introduction-to-Quantum-Cryptography
- Quantum cryptography is a scientific discipline that exploits the laws of quantum mechanics to perform cryptographic tasks, e.g., secure message transmission. It turns out that quantum phenomena are in fact very useful for that purpose: The level

- In this paper, we present and analyze efficient frame synchronization and frequency offset compensation scheme with ternary sequences for an orthogonal frequency division multiplexing (OFDM) system in Rayleigh fading channels. Frame synchronization
CPPjiexixm
- 由于在javascr ipt中不存在指针概念,故在xml页面调用OCX控件时,以前控件中的输出参数通过指针返回在这样的情况下行不通了,但本来就有返回参数,以及在同时有多个输出参数的情况下,依然想通过返回值返回,那就需要进行处理,然而怎么去处理呢?通过研究发现通过xml形式的字符串返回是一种解决方案,在解决这样的返回值的同时突然发现其实如果输入参数是结构体的话,也可以通过xml字符串的形式传入。然而怎么去解析它呢,而又怎么去做一个xml字符串呢,通过研究学习,以下是当然已有的解决方案。 开发环
