Description: UDP对QQ来说太重要了。 UDP和TCP是同一个层上的协议，都是通过IP层进行数据。。。 算啦，不扯这些了。 UDP针对的是不需要保证数据一定传输到的一种协议。因为IP 本身是会被随意丢弃的，所以TCP为确保数据可靠，会消耗大量的 资源，而且Socket架上去以后会出于保持链接的一种结构。 QQ本身不保持链接，数据是否可靠自己去验证，而且QQ里的数据 都是小包，尤其适应UDP的结构。最后对于multicast来说，UDP 是唯一可行的降低网络带宽负担的协议-UDP right QQ is so important. UDP and TCP is a layer with the agreement through the IP layer data. . . Forget it, do not pull these. UDP is aimed at not necessarily guarantee that the data transmission to an agreement. Because IP is will be randomly discarded, TCP to ensure reliable data, and will consume a large amount of resources, but to Socket shelves after link will be maintained for a structure. QQ link itself is not maintained, reliable data to verify themselves, but QQ, the data packets are, in particular to adapt the structure of UDP. Finally for multicast, UDP is the only viable network bandwidth to reduce the burden of agreement

Description: UPD 是USER DATAGRAM PROTOCAL 的简称，是一种在网络上提供的无连接的传输协议。用UDP通信有以下特点： 1、 数据传输不用建立连接，所以不可靠；
2、 数据的发送是面向整个网络的，任何一台在局域网内的计算机都可以接收到相同的数据；
具体实现很简单，但是现在在网络上很少看到这方面的代码；我也参考了VCKBASE上的关于UDP通信的原代码和一些书籍，写了这个简单的客户端，接收端程序，起到抛砖引玉的作用，希望能给初次接触UDP之BROADCAST编程的同志一些参考。
-UPD DATAGRAM PROTOCAL USER is the acronym, the network is available on the connectionless transport protocol. UDP communication with the following characteristics : 1, data transmission not connect, it is not reliable; 2. the data is sent across the network for any one of the LAN computers can receive the same data; specific Implementation is simple, but now the network rarely see the code; I have made reference to the VCKBASE the UDP communications on the original code and some books, was this simple client, receiving end procedures, the role played congregate, in hopes of giving the initial contact UDP Zhi BROADCAST programming comrades some reference.

Description: 基于UDP实现简单的可靠数据传输
由于数据是在不可靠的信道上传输的，因此数据在信道上传输时可能会发生比特错误，数据丢失。Rdt3.0及之前的版本都是停止—等待协议，它限制了网络底层硬件的能力。为克服这个问题引入了流水线技术，两个能恢复流水线中的错误的基本方法：第N个分组重发和选择性重复。综上，要实现差错编码，顺序号，计时器，分组确认，滑动窗口，拥塞控制。-simple UDP based on the reliable data transmission of data is not reliable transmission of the channel, therefore the data transmission channel may occur bit error, data loss. Rdt3.0 and earlier versions are stop-wait for the agreement, which limits the underlying network hardware capabilities. To overcome this problem the introduction of pipeline technology, both of which can restore pipeline error in the basic methods : section N to a re-issued and selective repeat. In sum, to achieve error coding, sequencing, the timer, a confirmation, sliding window, congestion control.

Description: UDP是一种面向非连接，不可靠的通讯协议，相对于TCP来说，虽然可靠性不及，但传输效率较高。所以在网络上仍有很大的用途。这几日需要了解下udp通讯的过程，上网发现这方面的资料还挺少。于是仔细的翻找了下msdn，基本上搞清楚了udp通讯的过程。做了一个测试的例子。希望对大家有帮助。
-UDP is a non-connection-oriented, reliable communication protocol, compared to TCP, Although less than reliability, high transmission efficiency. So the network is still great purposes. Need to understand the past few days under udp communication process, the Internet found that information It's small. So carefully looking for the next VARIANT basically clear the udp communication process. Done a test case. We want to help.
