The missing link that both of these things can be attributed to is the reduction in TCP timeout-based recoveries on the newer kernel because of the RFC 3517-related changes.
这些情况的原因中缺少的一环是在新内核中减少了TCP 基于超时的恢复机制，原因是与RFC3517有关的改变。
In TCP, a connection refers to a channel between two endpoints (in this case, a socket between the interfaces of two hosts).
在TCP中，连接(connection)是指两个端点之间的一个通道(在这种情况下，就是两台主机的网络接口之间的一个套接字)。
TCP guarantees that data is delivered in order (which is a good thing, considering TCP is a stream protocol).
TCP可以确保数据是按照次序发送的(考虑到TCP是一种流协议，这是一件好事)。
There may be several competing solutions (e.g., UDP versus TCP in communications) and a range of configurable choices for each solution (e.g., 10 threads versus 50 threads in a process architecture).
可能会有若干有竞争的解决方案（举例来说，通信中的UDP 对TCP）和大量的对于每个解决方案的可配置选择（举例来说，进程架构中的10线程 对50 个线程）。
Below the socket layer is the protocol layer, which contains the actual implementation of the protocol (in this case, TCP).
套接字层下面是协议层，该层包含协议的实际实现(本例中为TCP)。
TCP further provides the port abstraction, which enables a host to open multiple TCP connections in parallel.
TCP进一步提供了端口抽取功能，这使得主机可以并行地打开多个 TCP连接。
For reliable network services, many administrators prefer deployment of the TCP-IP protocol in their infrastructure.
对于可靠的网络服务，许多管理员喜欢在基础结构中部署TCP - IP协议。
Once in effect, these TCP TR profiles become the active policy governing connections.
生效之后，这些TCPTR配置文件成为有效的连接治理策略。
When a new TCP connection comes in from a client by means of a packet with the SYN bit set, the server creates an entry for the half-open connection and responds with a SYN-ACK packet.
当从客户机发来新的TCP连接时，数据包设置了SY n位，服务器就为这个半开的连接创建一个条目，并用一个SYN -ACK数据包进行响应。
With the large TCP window size, fewer acknowledgments are sent back, resulting in more optimized network communication between the sender and the receiver.
通过放大tcp窗口大小，发回的确认越少，发送者和接受者之间的网络通信就越流畅。
This interval might be measured in seconds or many minutes, depending on the TCP kernel Settings.
此间隔可能为数秒，也可能为数分钟，具体取决于TCP内核设置。
These are important fields in the TCP header, and the following section on TCP connection setup and shutdown will give you an even better understanding of what they are used for.
以上是TCP头中的重要字段，下面关于 TCP连接的建立和关闭的几节将使您更好地理解这些字段的用途。
This article explains what happens in the lower levels when an application issues the TCP system calls, as shown in Figure 1 below.
本文介绍在应用程序发布tcp系统调用时在较低级别中发生的情况，如图1所示。
By default, there is support for in-process, IPC, multicast, and TCP, and switching between all of them is as simple as changing the prefix on your connection string.
缺省情况下支持进程内通讯、IPC、广播和TCP。此外，协议间切换非常简单，仅需更改连接字符串的前缀即可。
Initiating a new connection in TCP and SCTP occurs with a packet handshake.
TCP和SCTP中对新连接的初始化是通过报文握手来完成的。
An option that refers to a packet at the end of the queue may require a full list traversal by the receiving TCP stack in order to identify which packet the option refers to.
一个指向队列末尾包的选项可能会迫使接收方的TCP协议栈遍历整个队列以判断此选项指向哪一个包。
In Listing 3 you can see the TCP header.
在清单3中，您可以看到TCP报头。
To test this, look at how TCP Wrappers resolves the hostname in the messages file, then amend the hosts.allow file accordingly.
为了查明这一点，在消息文件中查看TCPWrappers如何解析主机名，然后相应地修改hosts . allow文件。
It provides the reliable, ordered delivery of data like TCP but operates in the message-oriented fashion like UDP, preserving message boundaries. SCTP also provides several advanced features.
它提供了像TCP一样可靠、有序地发送数据的功能，但却以像UDP一样面向消息的方式来进行操作，这可以保护消息边界。
To verify that the message from the client to server is encrypted and not in clear text, the TCP Monitor can intercept and forward the request.
要验证从客户端到服务器的消息已被加密、不是明文形式，TCPMonitor可以截获并转发请求。
The discussion continued with Aston sharing details about TCPProxy - a proxy process that can be placed in a TCP stream, such as the HTTP connection between a browser and a server.
在讨论中，Aston接着分享了TCPProxy相关的详细情况——TCPProxy是一个TCP流中的代理进程，就像浏览器和服务器之间的HTTP连接一样。
