Description

The importance of quality of service (QoS) has risen with the recent evolution of telecommunication networks, which are characterised by a great heterogeneity. While many applications require a specific level of assurance from the network; communication networks are characterized by different service providers, transmission means and implementer solutions such as asynchronous transfer mode (ATM), Internet protocol version 4 (IPv4), IPv6 and MPLS.

Providing comprehensive coverage of QoS issues within heterogeneous network environments, “QoS Over Heterogeneous Networks” looks to find solutions to questions such as does QoS fit within heterogeneous networks and what is the impact on performance if information traverses different network portions that implement specific QoS schemes.

 Includes:

  • A series of algorithms and protocols to help solve potential QoS problems.
  • State of the art case studies and operative examples to illustrate points made.
  • Information on QoS mapping in terms of service-level specification (SLS) and an in-depth discussion of related issues
  • Chapters end-to-end (E2E) QoS, QoS architecture, QoS over heterogeneous networks and QoS internetworking and mapping.

An ideal book for graduate students, researchers and lecturers. System designers, developers and engineers will also find “QoS Over Heterogeneous Networks” a valuable reference

描述

隨著電信網路的最近演進,服務品質(QoS)的重要性在異質網路的特性下逐漸提升。許多應用程式需要網路提供特定的保證水準,而通信網路則由不同的服務提供商、傳輸方式和實現方案(如ATM、IPv4、IPv6和MPLS)所特徵化。

《異質網路上的QoS》全面探討了異質網路環境中的QoS問題,試圖找到解決以下問題的方案:QoS是否適用於異質網路,以及如果信息在實現特定QoS方案的不同網路部分之間傳輸,對性能的影響是什麼。

內容包括:
- 一系列算法和協議,以幫助解決潛在的QoS問題。
- 最新的案例研究和實例,以說明所提出的觀點。
- 關於服務水平規範(SLS)的QoS映射的信息,以及相關問題的深入討論。
- 關於端到端(E2E)QoS、QoS架構、異質網路上的QoS和QoS互聯網和映射的章節。

這本書是研究生、研究人員和講師的理想選擇。系統設計師、開發人員和工程師也會發現《異質網路上的QoS》是一本有價值的參考書。
