商品描述

Design your networks to successfully manage their growing complexity

 

 

Network professionals have often been told that today’s modern control planes would simplify their networks. The opposite has happened: Technologies like SDN and NFV, although immensely valuable, are exacerbating complexity instead of solving it. Navigating Network Complexity is the first comprehensive guide to managing this complexity in both deployment and day-to-day operations.

 

Russ White and Jeff Tantsura introduce modern complexity theory from the standpoint of the working network engineer, helping you apply it to the practical problems you face every day. Avoiding complex mathematical models, they show how to characterize network complexity, so you can understand it and control it.

 

The authors examine specific techniques and technologies associated with network control planes, including SDNs, fast reroute, segment routing, service chaining, and cloud computing. They reveal how each of these affects network design and complexity and help you anticipate causes of failure in highly complex systems.

 

Next, they turn to modern control planes, examining the fundamental operating principles of SDNs, such as OpenFlow and I2RS, network and other service function virtualization, content distribution networks, Layer 2 fabrics, and service chaining solutions. You’ll learn how each of these might both resolve and increase complexity in network design and operations and what you can do about it.

 

Coverage includes:

 

  • Defining complexity, understanding its components, and measuring it
  • Mastering a straightforward “state, speed, and surface” model for analyzing complexity
  • Controlling complexity in design, deployment, operations, protocols, and programmable networks
  • Understanding how complex network systems begin to fail and how to prevent failure
  • Recognizing complexity tradeoffs in service virtualization and service chaining
  • Managing new challenges of complexity in virtualized and cloud environments
  • Learning why constructs such as hierarchical design, aggregation, and protocol layering work and when they work best
  • Choosing the right models to contain complexity as your network changes

 

From start to finish, Navigating Network Complexity helps you assess the true impact of new network technologies, so they can capture more value with fewer problems.

設計您的網路以成功管理其日益複雜的情況

網路專業人士經常被告知,現代的控制平面將簡化他們的網路。然而事實卻相反:像是SDN和NFV這樣的技術,雖然非常有價值,但卻加劇了複雜性而非解決它。《網路複雜性導航》是第一本全面指南,旨在管理部署和日常運營中的複雜性。

Russ White和Jeff Tantsura從工作中的網路工程師的角度介紹了現代複雜性理論,幫助您將其應用於您每天面臨的實際問題。他們避免了複雜的數學模型,展示了如何表徵網路複雜性,以便您能夠理解並控制它。

作者們檢視了與網路控制平面相關的特定技術和技術,包括SDN、快速重路由、段路由、服務鏈接和雲計算。他們揭示了這些技術如何影響網路設計和複雜性,並幫助您預防高度複雜系統的故障原因。

接下來,他們轉向現代控制平面,檢視了SDN的基本操作原則,如OpenFlow和I2RS,網路和其他服務功能虛擬化,內容分發網路,第2層網路和服務鏈接解決方案。您將了解每個技術如何在網路設計和運營中解決和增加複雜性,以及您可以採取的措施。

本書涵蓋的內容包括:
- 定義複雜性,理解其組成部分並測量它
- 掌握一種簡單的“狀態、速度和表面”模型來分析複雜性
- 在設計、部署、運營、協議和可編程網路中控制複雜性
- 理解複雜網路系統開始失敗的原因以及如何預防故障
- 認識服務虛擬化和服務鏈接中的複雜性權衡
- 管理虛擬化和雲環境中複雜性的新挑戰
- 學習為何層次化設計、聚合和協議分層等概念有效並在何時最適用
- 在網路變化時選擇合適的模型來控制複雜性

從頭到尾,《網路複雜性導航》幫助您評估新網路技術的真正影響,以便在遇到更少問題的同時獲得更多價值。
