商品描述

Design, configure, and manage MPLS TE to optimize network performance

Almost every busy network backbone has some congested links while others remain underutilized. That's because shortest-path routing protocols send traffic down the path that is shortest without considering other network parameters, such as utilization and traffic demands. Using Traffic Engineering (TE), network operators can redistribute packet flows to attain more uniform distribution across all links. Forcing traffic onto specific pathways allows you to get the most out of your existing network capacity while making it easier to deliver consistent service levels to customers at the same time.

Cisco(r) Multiprotocol Label Switching (MPLS) lends efficiency to very large networks, and is the most effective way to implement TE. MPLS TE routes traffic flows across the network by aligning resources required by a given flow with actual backbone capacity and topology. This constraint-based routing approach feeds the network route traffic down one or more pathways, preventing unexpected congestion and enabling recovery from link or node failures.

Traffic Engineering with MPLS provides you with information on how to use MPLS TE and associated features to maximize network bandwidth. This book focuses on real-world applications, from design scenarios to feature configurations to tools that can be used in managing and troubleshooting MPLS TE. Assuming some familiarity with basic label operations, this guide focuses mainly on the operational aspects of MPLS TE-how the various pieces work and how to configure and troubleshoot them. Additionally, this book addresses design and scalability issues along with extensive deployment tips to help you roll out MPLS TE on your own network.

  • Understand the background of TE and MPLS, and brush up on MPLS forwarding basics
  • Learn about router information distribution and how to bring up MPLS TE tunnels in a network
  • Understand MPLS TE's Constrained Shortest Path First (CSPF) and mechanisms you can use to influence CSPF's path calculation
  • Use the Resource Reservation Protocol (RSVP) to implement Label-Switched Path setup
  • Use various mechanisms to forward traffic down a tunnel
  • Integrate MPLS into the IP quality of service (QoS) spectrum of services
  • Utilize Fast Reroute (FRR) to mitigate packet loss associated with link and node failures
  • Understand Simple Network Management Protocol (SNMP)-based measurement and accounting services that are available for MPLS
  • Evaluate design scenarios for scalable MPLS TE deployments
  • Manage MPLS TE networks by examining common configuration mistakes and utilizing tools for troubleshooting MPLS TE problems

"Eric and Ajay work in the development group at Cisco that built Traffic Engineering. They are among those with the greatest hands-on experience with this application. This book is the product of their experience."

Eric Osborne, CCIE(r) #4122, has been doing Internet engineering of one sort or another since 1995. He joined Cisco in 1998 to work in the Cisco Technical Assistance Center (TAC), moved from there to the ISP Expert team and then to the MPLS Deployment team. He has been involved in MPLS since the Cisco IOS(r) Software Release 11.1CT days.

Ajay Simha, CCIE #2970, joined the Cisco TAC in 1996. He then went on to support tier 1 and 2 ISPs as part of Cisco's ISP Expert team. Ajay has been working as an MPLS deployment engineer since October 1999, and he has first-hand experience in troubleshooting, designing, and deploying MPLS.

商品描述(中文翻譯)

設計、配置和管理MPLS TE以優化網絡性能

幾乎每個繁忙的網絡骨幹都有一些擁擠的連接,而其他連接則未充分利用。這是因為最短路由協議將流量發送到最短的路徑,而不考慮其他網絡參數,如利用率和流量需求。使用Traffic Engineering(TE),網絡運營商可以重新分配封包流量,以實現在所有連接上更均勻的分佈。強制將流量引導到特定的路徑上,可以充分利用現有的網絡容量,同時更容易提供一致的服務水平給客戶。

Cisco(r) Multiprotocol Label Switching(MPLS)提高了大型網絡的效率,是實現TE的最有效方式。MPLS TE通過將給定流量所需的資源與實際骨幹容量和拓撲相匹配,將流量流向網絡。這種基於約束的路由方法將流量引導到一個或多個路徑,防止意外擁塞並實現對鏈路或節點故障的恢復。

《使用MPLS的Traffic Engineering》提供了有關如何使用MPLS TE和相關功能來最大化網絡帶寬的信息。本書重點介紹了實際應用場景,從設計方案到功能配置再到管理和故障排除MPLS TE所使用的工具。在假設讀者對基本標籤操作有一定了解的基礎上,本指南主要關注MPLS TE的操作方面-各個組件的工作原理以及如何配置和故障排除。此外,本書還涉及設計和可擴展性問題,並提供廣泛的部署提示,以幫助您在自己的網絡上實施MPLS TE。

- 了解TE和MPLS的背景,並熟悉MPLS轉發基礎知識
- 了解路由器信息分發以及如何在網絡中建立MPLS TE隧道
- 了解MPLS TE的約束最短路徑優先(CSPF)以及影響CSPF路徑計算的機制
- 使用資源預留協議(RSVP)來實現標籤交換路徑建立
- 使用各種機制將流量引導到隧道中
- 將MPLS整合到IP服務質量(QoS)服務範譜中
- 利用快速重路由(FRR)來減輕與鏈路和節點故障相關的封包丟失
- 了解基於簡單網絡管理協議(SNMP)的測量和計費服務,這些服務可用於MPLS
- 評估可擴展的MPLS TE部署的設計方案
- 通過檢查常見的配置錯誤和使用故障排除MPLS TE問題的工具來管理MPLS TE網絡
