However, some people worry that even those tests that do what they say on the packet may not actually give the consumer useful information.
不过，也有人担心，即使真正可以做到他们标榜在包装盒上的事情的测试，也有可能不能提供给消费者有用的信息。
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.

In this case, you can see the raw Ethernet, IP, and TCP packet data, including the source and destination host information and packet options.
在这个示例中，您可以看到原始以太网、IP和TCP数据包，包括源、目标主机的信息以及数据包选项。
Finally, Listing 5 provides the content of the NFS packet, including the permissions (file mode), file size, ownership and other information.
最后，清单5提供了NFS数据包内容，包括权限(文件模式)、文件大小、拥有者和其他信息。
Once a connection is assigned to handle a particular request, the basic request information (HTTP headers, and so on) is sent over the TCP connection as a packet.
在分配连接来处理特定的请求后，基本请求信息(http头等信息)将以数据包的形式在TCP连接上发送。
As you can see, this response packet contains various bits of information about the specified location, including the data you're most interested in: its latitude and longitude.
正如您所看到的，这个响应包包含了关于指定位置的各种信息，包括我们最为关心的：经纬度。
Listing 5 shows the captured information about each packet, including packet size and IP address information.
清单5显示了捕捉到的关于每个数据包的信息，包括数据包的大小和IP地址信息。
Listing 3 shows the captured information about each packet, including packet size and IP address information.
清单3显示了所捕获的、有关每个数据包的信息，包括数据包的大小和IP地址信息。
Even on switched networks, you can gain some valuable information by running the packet-scanning tool on the host you want to investigate.
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。
So any external network sees the NAT router's IP address and the port number assigned by the router as the source computer information on each packet.
这样任何一台处于外部网络的计算机都会在发送给它的数据包里找到NAT的IP地址和由路由器分配的端口号。
When SSL is enabled, each packet of information is encrypted, so an application that requires many transmissions back and forth between client and server requires many encryptions.
在启用SSL时，每个信息包都将被加密，这样一来，需要在客户机和服务器之间来回进行很多传输的应用程序就需要进行很多加密。
VU scripts monitor your application while you use it and track what network information is sent and received at the packet level.
VUscripts当你使用它在包的级别上跟踪什么样的网络信息被发送和接受时，检测你的应用。
Another way to process the content from tcpdump is to save the raw network packet data to a file and then process the file to find and decode the information that you want.
处理来自tcpdump的另一个方法是将原始网络数据包数据保存到一个文件中，然后处理这个文件以便查找和解码出您想要的信息。
The MySQL protocol returns a specific packet type with the error information.
MySQL协议会传到一个带有错误信息的特殊数据包类型。
A ping flooding attack is a simple DDoS attack in which a computer sends a packet (ping) to another system with the intention of uncovering information about services or systems that are up or down.
ping洪水攻击是一种简单的DDoS攻击。在这种攻击中，一个计算机向另一个系统发送一个包(ping)，以找到关于服务或系统的信息。
While running commands such as netstat can provide useful information, sometimes you need to drill down more to the packet level.
虽然运行诸如netstat之类的命令可以提供一些有用的信息，但有时您仍然需要深入到数据包级别上进行更进一步的分析。
"One of the ways that we encode digital information is by its phase," Huntington said, "so what we've done is created a wave packet that's simultaneously a one and a zero in its phase."
“一种解密数码信息的方法是通过位相”，亨廷顿说，“于是我们生成了一个波包，它的位相同时处于0和1状态。”
While running commands (such as netstat) can provide useful information, sometimes you need to drill down more to the packet level.
虽然运行netstat等命令可以提供有用的信息，但有时您仍然需要深入到数据包作进一步分析。
The router is connected to at least two networks and decides which way to send each information packet based on its current understanding of the state of the networks it is connected to.
路由器至少连接至两个网络，并根据对当前所连网络状况的了解确定报文的发送方式。
Simulated results show QMRA achieves not only a low routing blocking ratio and a low average packet delay, but also a fast convergence, while the network state information is imprecise.
仿真结果显示了QMRA在状态信息不精确的情况下，具有较低的路由阻塞率和数据包的平均延迟，并且能够快速收敛。
Simulated results show QMRA achieves not only a low routing blocking ratio and a low average packet delay, but also a fast convergence, while the network state information is imprecise.
