商品描述

Quality of Service is expected to become the most important communications topic in the new millennium.

The acclaimed author, Gilbert Held, provides a comprehensive guide to obtaining a Quality of Service (QoS) capability in a Cisco hardware environment.

Today there are many aspects of the QoS 'puzzle' and Cisco is providing users with a wide range of solutions. Some solutions are well known but do not scale for use on the Internet or on a large corporate Intranet. Other solutions must be used in conjunction with different schemes for true end-to-end QoS. That is where this book comes in, providing a guide to the various pieces of the QoS puzzle.

Quality of Service in a Cisco Networking Environment:

  • Is a one-stop location to obtain complete and concise information about achieving QoS for applications transported over local and wireless area networks.

  • Provides a tutorial on the operation of different QoS techniques (IEEE 802.1p, 802.1Q, Differentiated Services, and RSVP).

  • Describes Cisco Router QoS and Switch QoS commands.

  • Gives examples of QoS configurations.

  • Includes a series of easy to implement IP and Frame Relay traffic enhancement techniques.

Written for the local and wide area network planners and managers, local area network administrators and router administrators, every chapter initially guides the reader through the theory behind a specific QoS technique. This information is then followed with a series of Cisco command examples tailored to a specific QoS technique. Readers learn both how a QoS technique operates and how to place it into effect in a Cisco environment.

商品描述(中文翻譯)

服務品質(Quality of Service)預計將成為新千年最重要的通訊議題。著名作家Gilbert Held提供了一本在Cisco硬體環境中獲得服務品質(QoS)能力的全面指南。

如今,QoS的「拼圖」有許多方面,Cisco為用戶提供了各種解決方案。有些解決方案眾所周知,但在互聯網或大型企業內部網絡上無法擴展。其他解決方案必須與不同的方案結合使用,才能實現真正的端到端QoS。這就是本書的用途,提供了QoS拼圖的各個部分的指南。

《在Cisco網絡環境中的服務品質》:
- 是一個獲取有關在本地和無線區域網絡上傳輸應用程式的QoS的完整且簡潔信息的一站式位置。
- 提供了有關不同QoS技術(IEEE 802.1p、802.1Q、差異化服務和RSVP)操作的教程。
- 描述了Cisco路由器QoS和交換機QoS命令。
- 提供了QoS配置的示例。
- 包括一系列易於實施的IP和Frame Relay流量增強技術。

本書針對本地區域網絡和廣域網絡規劃者和管理者、本地區域網絡管理員和路由器管理員撰寫,每一章節首先引導讀者了解特定QoS技術背後的理論。然後,提供一系列針對特定QoS技術量身定制的Cisco命令示例。讀者將學習到QoS技術的運作方式以及如何在Cisco環境中實施。
