　保证服务质量的QoS 路由(Quality of Service Routing) 是网络中解决QoS 问题的一项关键技术. QoS 路由 的主要目标是为接入的业务选择满足服务质量要求的传输路径,同时保证整个网络资源的有效利用. 度量参数选择问 题、寻路问题和路由信息不准确问题是QoS 路由中的几个主要研究内容. 本文围绕这三个方面,介绍了QoS 路由中的 主要问题及相关的解决办法,并探讨了今后QoS 路由可能的研究方向.-To ensure the quality of service QoS routing (Quality of Service Routing) is a network address QoS issues a key technology. QoS routing the main objective is to access business options to meet the requirements of the transmission path quality of service, while ensuring that the entire network efficient use of resources. metric parameters of choice, look for road and routing information is not accurate QoS routing problem is that several major research contents. This paper focus on three aspects, introduced the main issues in QoS routing and related solution, and to explore possible future research directions QoS routing.

C语言窗口通信，利用FPGA来实现和电脑的农信-C-window communication

本文主要阐述了DTMF的原理及如何在MATLAB上产生DTMF信号，主要涉及到电话拨号音合成的基本原理及识别的主要方法，利用 MATLAB 软件以及 FFT 算法实现对电话通信系统中拨号音的合成与识别。并进一步利用 MATLAB 中的图形用户界面 GUI 制作简单直观的模拟界面。 能够利用矩阵不同的基频合成 0 － 9 不同按键的拨号音，并能够对不同的拨号音加以正确的识别，实现由拨号音解析出电话号码的过程，完成对电话拨号音系统的简单的实验仿真。-This paper described the principle and how DTMF in MATLAB to generate DTMF signals, mainly related to the telephone dial tone of the basic principles of synthesis and identification of the main methods, the use of MATLAB software and the FFT algorithm on the telephone communication system dial tone Synthesis and Recognition . And further the use of MATLAB in the production of graphical user interface simple and intuitive GUI interface simulation. Able to take advantage of matrix synthesis of different fundamental frequency 0- 9 different keys of the dial tone and be able to different dial tone to be the correct identification, the dial tone from a telephone number to resolve the process of completion of the telephone dial tone system, a simple experiment simulation
