As packets arrive, they are filtered by their type, source address, destination address, and port information contained in each packet.
当信息包到达时，根据每个信息包中包含的类型、源地址、目的地址和端口信息来过滤它们。
These packets have headers, i.e. bits of data prefixed to every packet that contain information about the packet's source, destination, and protocol types.
这些信息包有头，即在每个包前面所附带的一些数据位，它们包含有关信息包的源、目的地和协议类型的信息。
Each data packet sent over the Internet contains information about its source and its destination.
每一个通过因特网传递的数据包都包含有它的来源和目的地。
The NAT router translates the inside global address of the packet to the inside local address and then checks the routing table before it sends it to the destination computer.
NAT路由器将这个数据包中的内部全局地址 (即其目的地址，译者)转换成内部本地地址后再查看路由表。
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。
Typically, a packet may travel through a number of network points with routers before arriving at its destination.
通常，一个数据包要途经大量路由器网络节点，然后才抵达目的地。
The interface on the destination (the server) receives the incoming SYN packet, places it on the ipintrq queue, and raises a software interrupt.
目的地(服务器)上的接口接收传入syn包，将其放在ipintrq队列中，并引发软件中断。
The optional match section of the iptables command specifies the characteristics that a packet should have to match the rule, such as source and destination address, protocol, etc.
iptables命令的可选match部分指定信息包与规则匹配所应具有的特征（如源和目的地地址、协议等）。
The output here specifies that the Ethernet packet contains IP data, specifies the overall packet size and time, and the destination and source Ethernet addresses for the packet.
这里的输出表明 Ethernet数据包包含了IP数据、全部数据包大小和时间，以及数据包的目标和来源地址。
Using an inside global address, the router sends the packet on to its destination.
通过内部全局地址，路由器将数据包转发至它的目的地址。
If the destination address is not in the routing table, the packet is dropped.
如果其目的地址不在这个路由表里，路由器就将数据包丢弃。
The network latency is the time between sending a request to a destination and the destination actually receiving the sent packet.
网络延时是向目的地发送请求到目的地实际接收到数据包之间的时间间隔。
The IP packet can now be delivered using the destination hardware address.
现在可以用目的地硬件地址发送IP数据包了。
What this means is that a packet from a computer with an unregistered address could reach a registered destination computer, but the reply would be discarded by the first router it came to.
这就是说一个数据包从一个未注册地址能够达到一台有注册地址的计算机，但是其响应数据包将会在它到达的第一个路由器就被丢弃 (这里说的是不是用 NAT 的情况，译者) 。
In the case where the destination is Server 2, the destination of the packet will be 192.168.194.13, and the source will be 192.168.206.131, which is the return address of the Load Balancer.
在本实例中，目的主机是Server2，包的目的地址将是192.168.194.13，资源地址将是192.168.206.131，资源地址是负载均衡器的返回地址。
Ethernet packet headers, including the Ethernet source and destination address, packet size and the Ethernet packet type.
Ethernet数据包头，包括Ethernet来源和目标地址，数据包大小和Ethernet数据包类型。
Bring a travel-size container of gentle laundry detergent to wash clothes at your destination. One little packet equals two whole outfits you can leave at home.
带上一包旅行装洗衣液，这样你就可以在到达目的地后洗你的脏衣服。一小包就可以洗两身衣服。
In that case, the stack will automatically send a copy of the packet to each destination specified in the binding entry.
在那种情况下，协议栈将会给每一个目的地址发送一份数据包拷贝。
This packet of data is then transmitted via the Internet to as close as possible to the physical destination of the telephone you're calling.
这个数据包，然后通过因特网传送到尽可能接近物理目的地的电话你通话。
When the chunks arrive at their final destination, IP assembles the pieces into the original packet.
当这些小数据包到达最终目的地时，IP协议又把这些数据块组装成原来的数据包。
The entire process is repeated at each router until the packet reaches its final destination.
这一整个过程在沿途各路由器周而复始，直至数据包抵达最终目的地。
Transport Layer protocols, such as the Transmission Control Protocol (TCP), the User Datagram Protocol (UDP), specify a source and destination port number in their packet headers.
传输层协议，诸如传输控制协议（TCP），用户数据报协议（UDP）， 会在它们的头部指定一个资源和目的地的端口号。
In computer network, the traditional routing selected on the basis of the destination address of IP packet.
计算机网络中，传统的路由是根据IP包的目的地址进行路由选择。
After consulting the LIB, the MPLS node forwards the packet toward its destination.
经过查找LIB之后，MPLS节点将包转发给它的目的地。
The IP header includes the source IP address where the packet originates, destination IP address where the packet is going, the transport protocol initiating the request.
IP数据头包括数据包产生地的主机ip地址，数据包即将前往的目的地ip地址，以及发出请求的传输协议。
In its header, each packet also carries the IP address of the final destination.
在报头中，每个包也携带最终目的地ip地址。
Each packet contain information about its origin and destination.
每个包包含关于它的起源和目的地信息。
Each packet contain information about its origin and destination.
每个包包含关于它的起源和目的地信息。
