TCP/IP详解 卷1 1.14

1.14 Implementations

实现

The de facto standard for TCP/IP implementations is the one from the Computer Systems Research Group at the University of California at Berkeley . Historically this has been distributed with the 4.x BSD system (Berkeley Software Distribution), and with the "BSD Networking Releases." This source code has been the starting point for many other implementations.

事实上 tcp/ip 标准实现是 UCB 的电脑系统研究组的一个产品。历史上曾是 4.X bsd 分布式系统（伯克利软件版本），随着 BSD 网络的发布。其源码曾是其他许多实现的起点。

Figure 1.10 shows a chronology of the various BSD releases, indicating the important TCP/IP features. The BSD Networking Releases shown on the left side are publicly available source code releases containing all of the networking code: both the protocols themselves and many of the applications and utilities (such as Telnet and FTP).

图 1.10 显示了不同 BSD 发型版本的年代表，显示了重要的 TCP/IP 特征。左边 BSD 网络的公开发行源码包含了所有的网络源码：既有网络协议本身，也有许多应用和工具（如 Telnet 和 FTP ）。

Throughout the text we'll use the term Berkeley-derived implementation to refer to vendor implementations such as SunOS 4.x, SVR4, and AIX 3.2 that were originally developed from the Berkeley sources. These implementations have much in common, often including the same bugs!

本文中，我们将使用术语 Berkeley-derived 实现表示厂家的实现方式，如 SunOS 4.X ， SVR4 ，及 AIX3.2 这些原本也由伯克利开发。这些版本有许多共同之处，也经常有同样的 bug 。⊙�n⊙ b 汗

Much of the original research in the Internet is still being applied to the Berkeley system― new congestion control algorithms (Section 21.7), multicasting (Section 12.4), "long fat pipe" modifications (Section 24.3), and the like.

许多当时的 Internet 研究仍然使用在 Berkeley 系统――新的冲突控制算法（ 21.7 节），组播（ 12.4 节），“长胖管道”修订（ 24.3 节）及其他的。
