OSPF and IS-IS : From Link State Routing Principles to Technologies
暫譯: OSPF 與 IS-IS：從鏈路狀態路由原則到技術

這本書描述並比較了 OSPF 和 IS-IS 的 IPv4 及 IPv6 版本。它通過基於鏈路狀態路由 (Link State Routing, LSR) 原則的分析來解釋 OSPF 和 IS-IS。書中故意將原則與技術分開。理解技術背後的原則使學習過程變得更容易且更扎實。此外，這有助於揭示 OSPF 和 IS-IS 的異同，並暴露它們的優勢和劣勢。關於原則的章節解釋了 LSR 協議的特性，並討論了獨立於技術的替代設計選項。關於技術的章節則提供了 OSPF 和 IS-IS 的全面描述，詳細程度足以滿足需要使用這些技術的專業人士。書的最後部分描述並討論了一組大型實驗，這些實驗使用 Cisco 路由器設計，旨在說明 OSPF 和 IS-IS 的各種特性。特別是，與同步機制相關的實驗在文獻中通常不常見。

Rui Valadas is a Full Professor at Instituto Superior Técnico, Universidade de Lisboa, Portugal, and a senior researcher of Instituto de Telecomunicações, Portugal. He was previously at the University of Aveiro, Portugal. He has had a regular teaching activity since 1986 and has been responsible for more than 20 University courses, at the various levels, BSc, MSc, and PhD, mainly in the area of Computer Networking. He set up, at both the University of Aveiro and Instituto Superior Técnico, laboratory infrastructures for teaching Computer Networks. He also created Cisco Academies at both Universities and is a CCNA instructor. He organized several courses targeted to industry with a laboratory component, namely a practical course on basic TCP/IP networking and a practical course on TCP/IP networking security. He has reasoned for long on the teaching methodologies of Computer Networking and published several papers on the subject. Among other management duties, he was the first director of the PhD course in Telecommunications jointly organized by the Universities of Minho, Aveiro, and Porto, in Portugal, and he coordinates since 2009 the BSc/MSc on Telecommunications and Informatics Engineering of Instituto Superior Técnico. His scientific activity concentrated on two main areas: Wireless Optical Communications (in the past) and Computer Networking, with an emphasis in Routing and Traffic Engineering aspects (currently). He supervised more than 30 PhD thesis and MSc dissertations. He played an active role is the specification of the IEEE 802.11 standard, being the author of 20 contributions to this standard. He participated in 25 research projects, both national and European, most of them as the responsible investigator. He is the author of 4 book chapters, and more than 100 papers in international journals and conferences. His papers deserved more than 2000 citations and an h-index of 22, according to Google Scholar.

Rui Valadas 是葡萄牙里斯本大學高等技術學院的全職教授，也是葡萄牙電信研究所的高級研究員。他曾在葡萄牙阿維羅大學任教。自1986年以來，他一直從事教學工作，負責超過20門大學課程，涵蓋學士、碩士和博士各個層級，主要集中在計算機網絡領域。他在阿維羅大學和高等技術學院建立了計算機網絡教學的實驗室基礎設施。他還在這兩所大學創建了思科學院，並擔任 CCNA 講師。他組織了多個針對產業的課程，並包含實驗室內容，特別是基本 TCP/IP 網絡的實用課程和 TCP/IP 網絡安全的實用課程。他長期以來對計算機網絡的教學方法進行了深入思考，並在該主題上發表了多篇論文。在其他管理職務中，他是葡萄牙米尼奧大學、阿維羅大學和波爾圖大學共同組織的電信博士課程的首任主任，自2009年以來，他負責高等技術學院的電信與資訊工程學士/碩士課程。他的科學活動集中在兩個主要領域：無線光通信（過去）和計算機網絡，當前重點在於路由和流量工程方面。他指導了超過30篇博士論文和碩士論文。他在 IEEE 802.11 標準的規範中扮演了積極角色，並為該標準撰寫了20篇貢獻。他參與了25個研究項目，包括國內和歐洲的項目，其中大多數是負責研究者。他是4本書章的作者，以及在國際期刊和會議上發表了超過100篇論文。根據 Google Scholar 的資料，他的論文獲得了超過2000次引用，h-index 為22。
