如何路由器发送包到个人电脑？
主动网络能更快速的发送包，但是需要更多的处理和带宽。
Proactive networks can convey traffic more quickly, but they involve more processing and bandwidth overhead.
要纠正这种丢失现象，首先需要发送端知道到发送包后并没有得到应答，然后重新传送这个包。
Correcting these dropped packets requires the transmitter to first recognize that the packet was not acknowledged, and then retransmit that packet.
您收集关于网络包接收和发送的数据。
You collect data on network packet receipt and transmission.
该网络使用TCP/IP 协议发送离散的数据包来传输信息。
The internet sends information as discrete packets of data using a suite ofprotocols known as TCP/IP.
然而，如果您减少这个缺省值，那么将需要发送更多的包，这可能会增加整体网络的使用率。
However, if you decrease the default, more packets will need to be sent, which could increase overall network utilization.
我们添加一个规则使它们可以写_，从而允许发送网络包。
We add a rule to allow them to write _ so as to allow sending network packets.
当传输信息的时候，它被数据发送者分成包，并标有源和目标电脑的信息，然后通过网络发送。
When information is transmitted, it is broken into packets at the sender of that data, labeled with information about the source and destination computers, and sent over the network.
这意味着您可以在两台主机之间开一个虚拟通道，通过这个通道，使得所发送的包的顺序及其实际传递都得到保障。
This means you can open a virtual channel between two hosts where the order of the packets sent and their actual delivery is guaranteed.
请求包通过不同的路由被发送。
这允许包的发送方表明所发送的数据类型，也使包的接收方能够在研究数据本身之前对包的数据略有认识(称为有效负载)。
That allows packet senders to indicate what type of data is being sent, and packet receivers to learn a bit about a packet's data (called its payload) before digging into the data itself.
这使得系统可以一次发送关于多个包的请求，并且在以后逐个检查响应。
This enables the system to send requests about a number of packages all at once and check the response at a later time one by one.
接电话，发送短信，翻包这些动作告诉面试者你的注意力不在面试上。
Answering your phone, sending texts or digging through your bag tells the interviewer that your focus is anywhere except on the interview.
您会发现，攻击者只要每十秒钟左右发送几个syn包就可以禁用特定端口。
You can see that the attacker will only have to send a few SYN packets every ten seconds or so to disable a specific port.
然后，使用netdev接收和发送探针以捕捉包长度数据。
Then, use the netdev receive and transmit probes to capture the packet length data.
对于低级的攻击，ping流可用于偷偷地查找信息，但是如果要截取向目标发送的包，则要求系统离线或停机。
At the low end, a ping flood can be used to uncover information covertly, but throttle up the packets being sent to a target or victim so that now, the system will go offline or suffer slowdowns.
路由器将其目的地址换成它保存在地址转换表中的那个，然后将数据包发送到那台计算机。
It changes the destination address to the one saved in the address translation table and sends it to that computer.
在这个例子中，您收集关于网络包接收和发送的数据。
In this example, you collect data on network packet receipt and transmission.
这意味着一个程序可以向网络中的另一方发送数据包，但这两者并不建立连接关系。
This means that one program can send off a load of packets to another, but that's the end of their relationship.
如果只显示您主机发送的数据包，这也表明从目标主机发送回的通信流有问题，因此反向路由有问题。
If only packets sent by your host are shown, this is another indication that the problem is with traffic sent back by the target and therefore the route back.
所有用户需要做的是编写(或安装，或使用)一个程序发送数据包到两个不同的目的地，并接收对方发来的数据包。
All that user needs to do is write (or install, or use) a program that sends packets to two different destinations and receives from both of them.
在这种情况下，获取统计数据有助于调试，比如接口发送或接收的数据包数量和发送或接收的RPC调用数量。
In such cases, getting statistics like number of packets sent or received and the number of RPC calls sent or received by that interface helps in debugging.
这种方法使数据能被分成许多信息包，然后使用不同路径将这些信息包发送到其想要的目的地。
This method enables the data to be divided into a number of packets and to be sent to its intended destination using different paths.
在应用程序的执行过程中，当需要打开文件、发送数据包或者使用系统资源时，它会对基础操作系统进行相应的系统调用。
As an application executes, it makes system calls to the underlying operating system whenever it needs to open a file, send a packet, or otherwise use system resources.
如何记录接收或发送的数据包？
这项更改将防止适配器发送任何数据包。
The change prevents the adapter from trying to send packets forever.
客户机通过发送syn同步数据包发起到一个主机(和特定端口)的连接。
A client initiates a connection to a host (and a specific port) by sending a syn synchronize packet.
为了响应此请求，它发送一个标准的http响应头、从相关管脚收集读数并以文本格式发送数据包。
In response to a request, it sends a standard HTTP response header, collects readings from the relevant pins, and sends the data package in text format.
为了响应此请求，它发送一个标准的http响应头、从相关管脚收集读数并以文本格式发送数据包。
