您可以选择阻止或通过数据包或您可以会创建一个规则，接受或拒绝数据包。
You have an option to block or pass the packet or you may create a rule that will accept or deny the packets.
如何记录接收或发送的数据包？
在所有情况下，都要寻找比较高的错误数据包、重新传输或丢失数据包传输数量，这些都说明网络忙。
In all cases, you are looking for a high level of error packets, retransmissions, or dropped packet transmission, all of which indicate that the network is busy.
数据包丢失或延迟到达情况下将启用阻塞控制，进一步限制性能以避免更多全局网络问题。
Packet loss, or late arrival, enables congestion control, which further limits performance to avoid more global networking issues.
RSCT实际上探测跨所有网络发送的心跳数据包是否丢失并判断准确的丢失(网络、NIC或节点故障)。
RSCT detects the loss of heartbeat packets that are sent across all the networks and determines the exact loss (network, NIC or node failure).
当网络的复杂性以及数据包要经过的主机或网关数量增加时，也会增加网络延时。
Network latency can also be introduced when the complexity of the network and the number of hosts or gateways that a packet has to travel through increases.
如果与传输或接收的数据包相比错误率很高，可能说明网络硬件有问题。
If the error rate is excessively high compared to the packets transmitted or received, then it may indicate a fault with the network hardware.
“(能够如此传送数据包)是建立一台量子计算机或量子通信设备的必经之路”，她说。
"[Being able to transfer data packets like this] is a necessary thing to do in order to build a proper quantum computer or a quantum communications device," she said.
要想记录每个接口上接收或发送的数据包，输入。
To record packets coming in and going out to any host on every interface, enter.
SCO数据包总是在规定时隙中以固定的周期(每2,4，或6时隙)进行传输。
SCO packets are always transmitted in defined time slots, at regular intervals (every 2, 4, or 6 slots).
一个叫做tcpflow的新工具与tcpdump相辅相成，它提供协议流分析和适当地重构数据流的方法，而不管数据包的顺序或重发。
A newer tool called tcpflow complements tcpdump and provides a way to do protocol flow analysis and to properly reconstruct data streams, regardless of packet order or retransmissions.
尽管您可以非法打开rt . jar并将您的定制实现或新数据包移入其中，但从技术上您就违反了您下载JDK时同意的协议了。
While you could crack open rt.jar and slide your custom implementation or new package into it, that would technically violate the license you agreed to when you downloaded the JDK.
这份备忘录包含一个草图，示意使用同轴电缆进行连接，并使用如同夏威夷的Aloha网或国防部的ARP网一样的数据包。
It contained a rough schematic drawing and suggested using coaxial cable for the connections and using data packets like Hawaii's AlohaNet or the Defense Department's Arpanet.
使用tcpdump显示发送到主机上的指定端口或从其接收的数据包，见清单12中的示例。
Use tcpdump to display packets sent to and received from the host on the specified port using the example shown in Listing 12.
tcpdump工具是一个比较老的工具，它从网上“嗅探”网络数据包，打印到stdout或记录在一个文件中。
The tcpdump tool is an older tool that "sniffs" network packets from a network and either prints them to stdout or logs them to a file.
如果主机是已知的，但是用户抱怨这个主机本身或它上面运行的应用程序没有响应，那么使用ping并查看数据包丢失率是否为0%(见清单6)。
If a host is known but you find that users are complaining that the host itself or an application running on it isn't responding, use ping and look for 0% packet loss (see Listing 6).
要开始处理，您首先需要使用snoop或tcpdump将数据写到一个文件，而创建一个通过网络的数据包的二进制记录。
To start, first you need to create a binary record of the packets going past on the network by writing out the data to a file using either snoop or tcpdump.
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.
这种加密应用到所有的IP数据包，而不会根据应用程序或服务调用情况进行启用或禁用。
This encryption is applied to all IP packets and is not enabled or disabled on a per application or per service invocation basis.
可以看到系统A向系统b发送了一个小数据包，然后等待响应包，已决定同意或拒绝登录请求。
Observe that system a sends a small data packet to system b, and waits for a response packet before granting or denying the login request.
它同时还记录被拒绝、绕行或中止的数据包以及允许通过和重定向的数据包。
It also logs on traffic that is rejected, detoured or stopped, and traffic that is permitted or redirected.
路由器可以创建或维护一个包含可用路由及其状态的路由表，同时根据这些信息，利用距离和成本算法为数据包选择最佳路由。
A router may create or maintain a table of the available routes and their conditions and use this information along with distance and cost algorithms to determine the best route for a given packet.
通过在字符串值中提供架构或表名称，可以轻松使用数据包的某一架构或表分组所有SQL。
By providing a schema or a table name in the string value, you can easily group all SQLs using a certain schema or table into their own packages.
如果一个数据包丢失或数据包到达的顺序混乱，那么应用程序应检测和依赖自己纠正此问题。
If a packet gets lost or the packets arrive out of order, then the application should detect and remedy the situation on its own.
可以指定应该扫描哪些到达的TCP数据包，丢弃不与ack、FIN、P SH、RST、syn或urg标志匹配的数据包。
You can specify which incoming TCP packets to scan and discard those that don't match the flags ack, FIN, PSH, RST, SYN, or URG.
如何移动运营商账单数据使用的字节或数据包？
How do Mobile Carriers bill data usage - by byte or by packet?
这是发送和接收终端，让信息像差错或丢失的数据包。
It is the sending and receiving endpoints that keeps information about such things as errored or missing packets.
状态检测技术主要是通过对IP层或TCP层的部分状态标志进行检测，来决定是拒绝还是允许数据包通过。
Technology of Stateful Inspection is mainly checking a part of stateful flag of IP step or TCP step, and decide whether let a data packet pass.
缺乏上下文或国家信息使之不能把包过滤用于数据包为基础的协议，如文件传送协议。
Lack of context or state information makes it impossible to use packet-filters for datagram-based protocols such as File Transfer protocol.
