一种典型的WAN由称为信息包交换机的电子设备通过通信线路连接而成。
A typical WAN consists of electronic devices called packet switches interconnected by communication lines.
信息包交换的过程相当于一个益智拼图游戏，该游戏中的图案在生产厂家被分解为许多拼合小图并装入胶袋。
Packet switching is similar to a jigsaw puzzle. The image that the puzzle represents is divided into pieces at the manufacturing factory and put into a plastic bag.
在客户端与服务器之间的通信和信息交换，以客户端对数据包进行格式化作为开始(如下所示)，并将其发送给服务器。
The contact and exchange of information between the client and the server begins with the client formatting a packet, as shown below, and sending it to the server.
即使在交换的网络中，通过对您所希望研究的主机运行数据包扫描工具，您就可以获得一些有价值的信息。
Even on switched networks, you can gain some valuable information by running the packet-scanning tool on the host you want to investigate.
使用以太网交换机，不会将数据包发送到所有端口，但是许多最新的交换机都提供了一个管理端口，该端口会将信息发送到所有的端口。
With Ethernet switches, packets are not echoed to all ports, but many modern switches provide a management port where the information is echoed.
通过这个工具包，您可以在Web应用之间使用众所周知的SOAP标准实现一种经济有效的信息交换方法。
With this toolkit, you can enable information exchange between Web applications in an economical and efficient manner, using the well-understood SOAP standard.
注意，现代交换机不会将 Ethernet数据包发送到每一个端口上，这通常会限制您从当前主机获取的信息量。
Note that with modern switches the Ethernet packets are not echoed to every port, which often limits the information you can extract to the current host.
任何人都可以在您的网络或远程计算机上使用包嗅探器查看交换的信息，有时甚至可以查看密码信息。
Anybody with a packet sniffer on your network or on a remote machine can view the information as it is exchanged, sometimes even password information.
捕获原始数据包，使您能够了解哪些主机正在与给定的主机进行通信、正在交换什么信息，以及正在使用哪些信息。
Capturing raw packets enables you to see which hosts are communicating with a given host, what information is being exchanged, and which are being used.
其中数据交换包括信息数据包的传输、控制、回执，数据同步等。
Data exchange includes transmission, control, receipt of message packages, and so on.
华为IAD可以提供8 -32路电话终端连接，将电话终端的信息转换成IP包，在NGN上实现软交换，并将计费信息通过RS232传给计费系统。
Huawei IAD (Integrated Access Device) provides 8-32 phone channels, transferring the information at phone terminals to IP packages to perform the soft switch and billing management system via RS232.
程序模块(12至22)处理借助于包交换通信网(30)传输的另外信令信息。
The program module (12 -22) processes other signaling information transmitted with the aid of the packet-switching communication network (30).
在交换机一端，服务器交换机能自动阻断来自某个服务器的无关的广播信息流，以消除相关的中断和包丢弃处理。
On the switch side, a server switch can automatically block irrelevant broadcast traffic from a server to eliminate the associated interrupt and packet-discard handling.
