Description

 

 

Understand OSPF, in-depth and the best way possible: through complete working implementations!

  • Power-packed CD contains exclusive, complete OSPF implementations, written in C++, with ports to Linux and Windows.
  • Discover never-before published optimization techniques, from the creator of OSPF!
  • For everyone interested in the practical aspects of Internet routing -- ideal for Cisco CCIE and other network certification candidates.

OSPF (Open Shortest Path First) is one of the most challenging routing protocols to understand-and one of the most important. In OSPF Complete Implementation, John Moy , OSPF's inventor and primary developer, walks networking professionals through a comprehensive OSPF implementation in C++, step-by-step. A perfect companion to Moy's OSPF: Anatomy of an Internet Routing Protocol (0-201-63472-4), this authoritative guide demonstrates how every part of the standard can be implemented, enabling readers to explore all of the protocol's "nooks and crannies", and to discover never-before-published optimization techniques. The highly valuable CD-ROM is serious software; it contains the complete implementation, as well as ports that can transform Linux or Windows systems into full-fledged OSPF routers. Moy explains OSPF's functional specifications, software architecture, and key building blocks. An ideal resource for everyone interested in practical Internet routing: netadmins, protocol designers, protocol software developers, and others involved in designing, developing, or managing TCP/IP networks using OSPF.

John T. Moy is developer and main inventor of the official OSPF protocol specification.

描述

深入了解 OSPF，以最佳方式：透過完整的工作實現！

- 強大的 CD 包含獨家、完整的 OSPF 實現，使用 C++ 編寫，並提供 Linux 和 Windows 的端口。
- 發現從 OSPF 的創造者那裡從未發表過的優化技巧！
- 適合所有對互聯網路由的實際方面感興趣的人，特別適合 Cisco CCIE 和其他網絡認證考試的候選人。

OSPF（Open Shortest Path First）是最具挑戰性的路由協議之一，也是最重要的之一。在《OSPF Complete Implementation》中，OSPF 的發明者和主要開發者 John Moy 逐步引導網絡專業人士進行全面的 C++ OSPF 實現。這是 Moy 的《OSPF: Anatomy of an Internet Routing Protocol (0-201-63472-4)》的完美伴侶，這本權威指南演示了如何實現標準的每個部分，使讀者能夠探索協議的所有“角角落落”，並發現從未發表過的優化技巧。這個非常有價值的 CD-ROM 是一個嚴肅的軟件；它包含完整的實現，以及可以將 Linux 或 Windows 系統轉換為完整的 OSPF 路由器的端口。Moy 解釋了 OSPF 的功能規範、軟件架構和關鍵構建塊。這是一個理想的資源，適合所有對實際互聯網路由感興趣的人：網絡管理員、協議設計師、協議軟件開發人員以及使用 OSPF 設計、開發或管理 TCP/IP 網絡的其他人。

John T. Moy 是 OSPF 官方協議規範的開發人員和主要發明者。
