当应用软件向另一主机发送数据时，UDP协议生成一个数据头，包括源端口，目的地端口。这些端口提供为送达信息所需要的地址。
When an application wants to send data to another host, UDP builds a header that includes a source port, a destination port which provides an address for delivering messages.
这意味着路由器在收到数据封包时就会去除以太网的数据头信息，加上低一层的数据头信息(以太网层或者其他层的)，然后发送给下一方。
This means that routers strip off the Ethernet header upon reception of a packet, and then add a new lower layer header-ethernet or otherwise-when the packet is forwarded.
正如我们所看到的，当应用软件向另一主机发送数据时，每一层都把自己的信息添加到一个数据头中。而这个数据头又被下一层中的协议包装到数据体之中。
As we'll see, when an application sends data to another host, each layer adds its own information to a header that is encapsulated as data by the protocol in the layer below.
清单5显示了用于创建与xev监视程序之间的非阻塞链接的createpipe子例程，以及用于将数据头信息输出到STDERR中的printheader子例程。
Listing 5 shows the createPipe subroutine used to create a nonblocking link to the xev monitoring program, as well as the printHeader subroutine, which prints the data header information to STDERR.
这些数据对于公司的前景不是个好兆头。
“我们的理论在我们开始在数据中观察它们之前，预测了这些波头的摆动，”他说。
"Our theory predicted these oscillations before we began to observe them in our data," he says.
INVALID状态指出该信息包与任何已知的流或连接都不相关联，它可能包含错误的数据或头。
INVALID state indicates that the packet is not associated with any known stream or connection and it may contain faulty data or headers.
不过在某些环境下需要更多控制信息并将其以附加头的形式作为负载数据的前缀，如上面图1所示。
But under some circumstances, more control information is needed and is prefixed to the payload data in the form of additional headers, as shown in Figure 1 above.
清单6显示了一个指定只有自2003年11月11日以后修改的数据才送回服务器的头。
Listing 6 shows a header request specifying that only data that has been modified since November 11, 2003 be sent back from the server.
消息数据前面的附加头的类型更加丰富化。

大的URL、大量提交数据和过多的头都会增加请求的大小。
Large URLs, large post data, and excessive headers can also increase the size of a request.
它设置所需的http头，然后将数据发送给中间层服务。
It sets any required HTTP headers and then sends the data to the mid-tier service.
头两个问题与数据传输相同。
The first two problems are the same as those with data transfer.
这个MqttPayload对象包含应用程序数据和任何此发布的协议头。
The MqttPayload object contains both the application data and any protocol headers for this publication.
基于标头改变数据处理程序的行为。
如果需要per - CPU数据(这在检查区段头时确定)，那么就分配per - cpu块。
If per-CPU data is needed (as determined in the section header checks), a per-CPU block is allocated.
负载数据的性质由MQCIH头的Format字段表明。
The nature of the payload data is indicated by the Format field of the MQCIH header. Figure 3 shows this use of Format
不过，对于方法的输入参数不包括协议标头的数据处理程序，我们应如何访问它们？
However, for Data Handlers the method input parameters do not include the protocol headers, so how do we access them?
例如，通过在您的数据服务中设置某个缓存消息头，您可以将浏览器作为一个自由缓存使用。
For example, by setting certain caching headers in your data services, you can use the browser as a free cache.
如果没有任何MQ标头，还可以将数据视为带分隔符的数据。
If there is no MQ Header, then the data would also be treated as delimited.
在分区数据库环境中，执行LOAD_ONLY操作期间，分区头用于验证该文件是否只包含属于特定数据库分区的数据。
In a partitioned database environment, during a LOAD_ONLY operation, partition headers are used to verify that the file only contains data belonging to a specific database partition.
应用程序数据部分包含所有实际消息数据(有效负载)和任何附加头，比如传输头或IMS信息头。
The application data section contains all actual message data (payload) and any additional headers, such as the transmission header or the IMS information header.
在阅读本文之后，您将能够创作基于MQ标头动态地转换数据的可重用数据处理程序。
After reading this article you will be able to author reusable data handlers that dynamically transform data based on a MQ header.
我们可对附加头进行约束，即应用程序数据可以选择性地在负载数据前包含一个或多个消息头。
The additional headers can be chained, that is, the application data can optionally contain one or more headers before the payload data.
完成这些之后，关闭数据库并使用HTTP标头强制浏览器打开登录页面。
Once that's complete, close the database and use HTTP headers to force the browser to go to the login page.

Judging by the recent jobs figures, its growth in the first few months of 2007 May be lower still.
当创作数据绑定时，会将消息标头传入读或写方法，并允许协议标头中的字段确定转换逻辑。
When authoring a Data Binding the message headers were passed into the read or write method, allowing transformation logic to be determined by a field in the protocol header.
