408. A new concept called the Storage Area Network (SAN)(存储区域网络)could offer an answer to the increasing amount of data that needs to be stored in an enterprise network environment.

409. A Storage Area Network （SAN, 存储区域网）does not need to be a physically separate network, either. It can be a dedicated sub-network, carrying only the business-critical I/O traffic between servers and storage devices. A SAN, for example, would not carry general-purpose traffic such as e-mail or other end-user appliestions. This type of net avoids the

unacceptable trade-offs inherent in a single network for al 1 applications

SAN不需要在物理上是一个单独的网络。它可以是一个专用的子网，只在服务器与存储设备Z间传输关键业务I/O信息。例如，SAN不传送通用意义上的信息，如电子邮件或其它最终用户应用程序。这类网络避免了单一网络中固有的不能接受的拆衷410.Plug and Play（艮卩扌甫艮卩用）-------------------------------------------------- b asically a set of PC architecture specifications -------- is an effort by hardware

411.IPV6 ---- the next-goneration nctworking protocol --------- promises to changc the way corporate networks and the Internet work?IPv6 （also referred to as IPng or ,simply, v6）will eliminate some of IPv4, s shortcomings that have appeared as a result of the global Internet explosion. IPv6 is a much-needed improvement, promising easier一to—obtain IP addresses, cheaper and faster routing, and such features as quality of service （QOS, IK 务质量）and encrypt ion （加密）.

IPv6——下一代的连网协议，有希望改变公司网络和因特网的工作方式。IPv6也叫做IPng,或简称v6,将消除IPv4因全球因特网爆炸性发展而帯来的某些缺点.IPv6是--项非常需要的改进，它许诺更容易获得IP地址，更快更便宜建立路由以及具有较好的服务质量（QOS）和加密等特点。

412.RISC processors, because they are software-programmable, provide the flexibility to adapt to the rapidly evolving data communications market ? However, they lack ASIC-level per forma nee because of their general ized（jJ=| 化的）architectures ? ASICs solve the per forma nee problem but can take 12 to 18 months to develop; require scarce, specialized en gineering talent to impleme nt; and have fixed functionality. Mod if ying an ASTC can cost six to nine months in time-to-market and, even worse, can force forkl ift upgrades on customers who own equipment based on out-of-date si 1 icon（硅）?

RISC处理器由于是可编程的，故提供了灵活性，以适应快速发展的数据通信市场。然而，由于它们采用归一化的体系结构，故缺乏ASIC档次的性能。ASTC解决了性能问题，但要花12至18个月时间来开发，并需要不多见的专门工程人才来具体实现，同时具备固定不变的功能性。修改ASTC可能要以推迟6至9个月产品上市的时间为代价。更有甚者，可能强迫拥有基于过时硅电设备的客户升级。

413.------------------------------ Hand-held devices （手持设备）are more 1 imi ted than desktop computers in several important ways? Thei r screens are small perhaps a few inches square or able to display only a few lines of text~and they， re

ing data takes extra time, as happens with a personal digital assistant' s （PDA） handwriting-recognition capabi 1 ities?They have less processing power and memory to work with, and their wireless nctwork connections have less bandwidth and are slower than those of computers hard-wired to fast LANs.

手持设备在多个重要的方面比台式计算机更受限制。它们的屏幕很小一一也许只有儿平方英寸或者只能显示儿行文本信息，

它们常常是单色的而不是彩色的。它们的输入功能局限于几个按键或数字键，或者像个人数字助理（PDA）手写体识别功能那样，输入数据要花很长时间，它们所拥有的工作处理能力和内存都较小。比起那些通过计算机硕连线与快速局域网相连的连接，它们的无线网络连接带宽较窄，速度也较慢。

414.Digital subscriber line technology comes in a bewildering variety of flavors, but they al 1 have one thing

in common ---- they use various modulation techniques to turn those plodding "last mile'7 loops of copper between

the customer premises and the telco's（电信公司）central office into high-speed data and voice carriers. Most of the focus has bee n on ADSL （asymmetric digital subscriber lin e）, which delivers rates of 32 Kbps to 8. 192 Mbps downstream, and 32 Kbps to 1. 088 Mbps upstream to the network, whi 1 e providing phone service at the same time on the same 1ine.

数字用户环路（DSL）技术有儿种令人疑惑的不同变种，但它们都有一样公共的东西一一它们用不同的调制技术，把用户房屋和电话公司的中心局之间低速的〃最后一英里〃铜线回路变成高速的数据和话咅的载体。（人们）注意力多数集中在

ADSL（不对称数字用户环路）上，它给出32K至8. 192Mbps的下行速度和32K至1. 088Mbps的上行速度,同时在同一线路上提供电话服务。

415.But even without a new OS, these features can be utilized. Leveraging Windows' driver model, specialty vendors will offer drivers that can fully exploit these integrated features. Thus providing dramatically improved or arguably, finally usable-video and speech capabilities? Of course, this Pentium-Windows chasm provides an opportunity for other operating system vendors such as Red Hat and Be Inc. That is assuming that they can react like the Microsoft of old.

但即使没有新的OS,也能利用这些特性。通过利用Windows的驱动程序模型，专业公司将提供全面利用这些内在特性的驱动程序，从而提供戏剧性改进了的一一或者还有争议，但最终能使用的视频与语咅功能。当然，这场Pentium-Windows 的角逐为其它

的操作系统公司，如Red Hat公司和Be公司提供了机会。这是假设他们能像过去的微软公司那样工作。

416.Given the relative quickness of software development, one would think that software solutions would lead the computing agenda for many years. But as software delays have become more profound and commonplace, hardware-featured solutions are beginning to offer better solutions than their software counterparts. And given the improving capabilities of hardware development, hardware vendors will become the clear leader in this race.

在假设软件开发较快的情况下，人们会认为软件方案将在计算领域独领风骚许多年，但随着软件开发的延迟变得更严重、更

常见，以硬件为特色的方案开始优于同类软件方案。在硬件开发能力得到改进的情况下，硬件厂家将在这场竞赛中明显领

先。

417.Linux是不是像Windows那样太大以及需要系统资源太多，以致于不能满足嵌入式系统的约束要求呢？与Windows 不同，Linux本来就是模块化的，并且能够很容易缩减成紧缩配置，这种配置几乎与DOS差不多大，甚至能放到一张软盘上。此外，因为Linux源码是免费可用的，所以可以按照独特的嵌入式系统要求改编该操作系统。

这样，并不令人惊奇，开放源代码Linux 5经建立了一个新的操作系统开发和支持范例，在那里数以千计的开发人员继续贡献于不断发展的Linux代码库。此外，儿十家而向Linux的软件公司已经出现-一-它们热切支持那些为建立从工厂自动化到智能设备范围很广的应用系统的开发人员的需求。

Is Linux , like Windows , too large and demanding of system resources to fit the constraints of embedded system? Unlike Windows , Linux is inherently modular and can be easily scaled into compact configurations , barely larger than DOS , that can even fit on a single floppy. What' s more, since Linux source code id freely available, it' s possible to customize the OS according to unique embedded system requirements.

It" s not surprising, then, that open source Linux has created a new OS development and support paradigm wherein thousands of developers continual 1y contribute to a constantly evolving Linux code base. Tn addition, dozens of Linux-oriented software companies have sprung up eager to support the needs of developers building a wide range of applications, ranging from factory to intelligent appliances?

41&对许多嵌入式系统，为了适应诸如RAM、固态盘、处理机速度，以及功耗的约束，嵌入的Linux的主要任务是，使系统所需的资源最小。嵌入式操作可能需要从一个芯片盘或紧凑闪存固态盘上自举；或者自举和运行在没有显示器和键盘的坏境，或

经由以太网连接，从远程设备装入应用程序。

现成的小Linux有许多来源，其中有H益增多的面向应用的Linux配置和分发版，这些都被修改成适用于特定的应用。例如路由器、防火墙、互联网/网络设备、网络服务器、网关等。

你也可选择建立你自己喜欢的嵌入式Linux,从一个标准分发版开始，略去不要的模块。虽然如此，还应该考虑从别人的工作配置基础上开始你的工作，因为他们的版本的源码可用于那个目的。最好的是，这种在别人努力的成果上建立系统, 在Linux团体中不仅是完全合法的，也被鼓励。

For many embedded systems , the main chai lenge in embodding Linux is to minimize system resource requirements in order to fit with in constraints such as , RAM solid state disk （SSD）, processor speed, and power con sumption ? Embedded operation may require booting from a DiskOnChip or CompactFlash SSD ; or booting and running without a display and keyboard ; or loading the application from a remote device via an Ethernet LAN connection.

There are many resources of ready-made smal1 foot-print Linux? Ineluded among these are a growing nuniber of app1ication-oriented Linux configurations and distributions that are tuned to specific applications. Some examples are routers, firewal1s , internet/network appliances , network servers , gateways , etc.

You may also opt to create your own flavor of embedded Linux , starting from a standard distribution and leaving out modules you don' t need. Even so , you should consider jump-starting your efforts by beginning with someone else" s working configuration ,since the source code of their version will be available for that purpose ?Best of all , this sort of building on the efforts of others in the Linux community is not only completely legal but also encouraged!

419. 一个长期目标可以是开发交互式程序变换系统，它帮助程序员把程序并行化并提供反馈和指导。这种想法的问题是半自

动化程序变换实现办法仍然是现行研究的对象，甚至对于顺序程序也是。在中期内，导出实际的并行程序的、产品质量变换

程序未必可能出现。传统的方法是讲授一些算法，然后用具有明显并行性的程序设计语言明确地表达它们。这很可能是更成

功的，特别是因为已知的一些并行算法的主要部分很大，并且在迅速地增长。初步迹象表明，倘若语言与支持工具充分的

话，书写并行软件不比书写顺序软件显著地更困难。

A long tem goal could be to develop interactive program transformation systems that assist programmers in parallelizing programs and provide feedback and guidaneo. The problem with this idea is that the approach of semiautomatic program transformations is still an object of active research, even for sequential programs. In the medium terms, a product!on-quality transformer for deriving realistic, parallei programs is uniikely to appear. The traditional method of teaching algorithms is likely to be more successful, especially since the body of known parallel algorithms is large and growing rapidly. Initial indications seem to be that writing parallel software is not significantly harder than writing sequential software, provided the languages and support tools are adequate.
