MPLS and Next-Generation Networks: Foundations for NGN and Enterprise Virtualization (Network Business) (Paperback)
by Azhar Sayeed, Monique Morrow

attachments/month_200611/6432621375.jpg

Book Description

Understand the business case for deploying MPLS-based services and solutions

  • Provides network managers and architects a precise MPLS primer
  • Defines MPLS service problems and their associated solutions
  • Includes ROI models for MPLS-based solutions
  • Discusses pros and cons of various options for each MPLS service

Network managers often question the value that MPLS brings to their business environment. This book provides them with a precise guide for evaluating the benefits of MPLS-based applications and solutions. The book guides the network manager through the business case for MPLS by exploring other technology alternatives, including their applications, benefits, and deficiencies. Understanding the service creation process as the basis for MPLS-based solutions is pivotal when describing the benefits that MPLS offers. Furthermore, the book explores MPLS technology and its components, providing an overview of the architecture necessary to reap the true advantages that MPLS brings to a service provider or enterprise network. These advantages include new revenue opportunities and a total cost of ownership reduction that positively impacts a company's bottom-line. ROI models and case study examples further confirm the business impact and help decision-makers create a blueprint for MPLS service creation. Specific aspects such as security, network management, advanced services and the future of the technology complete the book, helping decision makers assess MPLS as a candidate for implementation. In short, you can use this comprehensive guide to understand and build a business case for the inclusion of MPLS in your network.

Practical Color Management

attachments/month_200611/2123717826.jpg

By Eddie Tapp, Rick Lucas
First Edition October 2006 

Book description

The second book in this acclaimed series from noted photographer and digital imaging expert Eddie Tapp delves into color management, a topic that has needlessly become a mystery to experienced digital photographers, whether they're avid amateurs, serious students, or working professionals. With his easygoing yet authoritative style, Eddie sheds light on this topic and supplies an understanding of color management that readers apply to their own work.

Clear and concise, this highly visual book explains how color management is a part of the overall photographic workflow. Eddie demonstrates the three stages of color managed workflow, from choosing a color space, to calibrating your devices, to applying appropriate profiles, and shows you exactly what you need to know and why you need to know it. Color management scientist Rick Lucas contributes a chapter on the hard-core technical aspects. Other books on color management are much too long, involved and intimidating. This absorbing book sets the right tone and supplies you with key answers quickly.

Our Eddie Tapp on Digital Photography book series brings you the focused knowledge you need on specific areas of digital photography. Acknowledged as one of the premier trainers of digital imaging in the world, Eddie brings his teaching experience to bear on issues that other books gloss over or bury under general coverage. Now, you don't have to buy a doorstop-sized book to get the key information you need on color management, efficient workflow, or a variety of other specific digital imaging topics.

Eddie Tapp on Digital Photography also covers workflow setup; advanced and professional production techniques; controlling digital color and tone; creative enhancement techniques; and more. This series is a perfect complement to O'Reilly's general list on Photoshop and digital photography, and offers you focused books that cover technical issues at prices that are affordable and solutions that are quickly accessible. We're thrilled that Eddie Tapp has finally agreed to publish books -- and with O'Reilly.

最新全球超級計算機500強排行榜將於下週一正式公佈.從中可以看出,更多採用AMD雙核Opteron處理器和Infiniband互連技術的計算機出現在排行榜上.attachments/month_200611/1459738481.gif
  在上榜的超級計算機中,有113台採用了AMD處理器,所佔比例為22%,遠遠超過去年同期的11%.與之相比,採用英特爾處理器的計算機僅有261 台,所佔比例為52%,低於去年同期的333台,跌幅創造了新高.AMD憑借雙核處理器從英特爾搶走了不少市場份額,而英特爾也正依托雙核Xeon處理器緊緊追趕.上週一,英特爾還發佈了四核Xeon處理器,預計在AMD同類產品發佈之前,四核Xeon處理器的銷量可以達到100萬片.

  勞倫斯-伯克利國家實驗室研究員埃裡奇·斯特羅邁爾(Erich Strohmaier)表示:「英特爾過去兩三年主宰了超級計算機排行榜,去年所佔比例達到了66%,因此出現下滑也很正常.」他同時稱,採用 Woodcrest核心的英特爾雙核處理器已經出現在排行榜上,未來一段時間有望進一步普及.如果英特爾在四核處理器領域超越AMD,未來6到12個月的排名還會有較大變化.

  在最新排行榜上,採用IBM處理器的超級計算機數量為93台,所佔比例為18.6%,高於去年同期的14.6%,但落在了AMD的後面.斯特羅邁爾預計,在未來的超級計算機排行榜上,採用英特爾和AMD處理器的超級計算機數量還將進一步增長,而採用 Power處理器的超級計算機數量將繼續下滑,因為只有IBM採用Power處理器.但是,IBM是全球最大的超級計算機廠商,上榜計算機中有239台來自於IBM,其中包括排名首位的藍色基因/L(Blue Gene/L).

  在上榜超級計算機中,大多數仍然將 Gigabit Ethernet作為集群互連方式,共有211台計算機採用了這一方式,但低於半年前的256台.此外,有79台超級計算機採用Myrinet互連方式,同樣少於半年前的87台.與之相比,採用Infiniband互連方式的超級計算機則由半年前的36台增至87台.
