Definitive MPLS Network Designs (Paperback)

Field-proven MPLS designs covering MPLS VPNs, pseudowire, QoS, traffic engineering, IPv6, network recovery, and multicast

• Understand technology applications in various service provider and enterprise topologies via detailed design studies
• Benefit from the authors’ vast experience in MPLS network deployment and protocol design
• Visualize real-world solutions through clear, detailed illustrations
• Design studies cover various operator profiles including an interexchange carrier (IXC), a national telco deploying a multiservice backbone carrying Internet and IP VPN services as well as national telephony traffic, an international service provider with many POPs all around the globe, and a large enterprise relying on Layer-3 VPN services to control communications within and across subsidiaries
• Design studies are thoroughly explained through detailed text, sample configurations, and network diagrams

Definitive MPLS Network Designs provides examples of how to combine key technologies at the heart of IP/MPLS networks. Techniques are presented through a set of comprehensive design studies. Each design study is based on characteristics and objectives common to a given profile of network operators having deployed MPLS and discusses all the corresponding design aspects.

The book starts with a technology refresher for each of the technologies involved in the design studies. Next, a series of design studies is presented, each based on a specific hypothetical network representative of service provider and enterprise networks running MPLS. Each design study chapter delivers four elements. They open with a description of the network environment, including the set of supported services, the network topology, the POP structure, the transmission facilities, the basic IP routing design, and possible constraints. Then the chapters present design objectives, such as optimizing bandwidth usage. Following these are details of all aspects of the network design, covering VPN, QoS, TE, network recovery, and—where applicable—multicast, IPv6, and pseudowire. The chapters conclude with a summary of the lessons that can be drawn from the design study so that all types of service providers and large enterprise MPLS architects can adapt aspects of the design solution to their unique network environment and objectives.

Although network architects have many resources for seeking information on the concepts and protocols involved with MPLS, there is no single resource that illustrates how to design a network that optimizes their benefits for a specific operating environment. The variety of network environments and requirements makes it difficult to provide a one-size-fits-all design recommendation. Definitive MPLS Network Designs fills this void.

“This book comes as a boon to professionals who want to understand the power of MPLS and make full use of it.”

經過實地驗證的MPLS設計，涵蓋MPLS VPN、虛擬線路、QoS、流量工程、IPv6、網路恢復和多播。

通過詳細的設計研究，了解各種服務提供商和企業拓撲中的技術應用。

從作者在MPLS網路部署和協議設計方面的豐富經驗中受益。

通過清晰明確的插圖，形象化地呈現現實世界的解決方案。

設計研究涵蓋各種運營商配置文件，包括互換運營商（IXC），部署多服務骨幹網路承載互聯網和IP VPN服務以及國家電話流量的國家電信公司，擁有全球各地多個POP的國際服務提供商，以及依賴Layer-3 VPN服務來控制子公司內部和跨子公司通信的大型企業。

通過詳細的文本、示例配置和網路圖解詳細解釋設計研究。

《Definitive MPLS Network Designs》提供了如何在IP/MPLS網路的核心結合關鍵技術的示例。透過一系列全面的設計研究介紹了技術。每個設計研究都基於已部署MPLS的網路運營商的特定假設網路，並討論了所有相應的設計方面。

書籍以每個涉及設計研究的技術回顧開始。接下來，呈現了一系列設計研究，每個設計研究都基於特定的假設網路，代表運營商和企業運行MPLS的網路。每個設計研究章節提供四個元素。首先是網路環境的描述，包括支持的服務集合、網路拓撲、POP結構、傳輸設施、基本IP路由設計和可能的限制。然後，章節提出設計目標，例如優化帶寬使用。接下來是網路設計的所有方面的細節，包括VPN、QoS、TE、網路恢復，以及（適用的話）多播、IPv6和虛擬線路。章節以總結設計研究中可以得出的教訓結束，以便各種類型的服務提供商和大型企業MPLS架構師可以根據其獨特的網路環境和目標適應設計解決方案的各個方面。

儘管網路架構師有許多資源可以尋求有關MPLS涉及的概念和協議的信息，但沒有一個單一的資源可以說明如何設計一個在特定操作環境中最大程度地優化其效益的網路。各種網路環境和要求使得提供一個適合所有的設計建議變得困難。《Definitive MPLS Network Designs》填補了這一空白。

“這本書對於想要了解MPLS的威力並充分利用它的專業人士來說是一個福音。”
