{"product_id":"9780133757507","title":"OSPF Complete Implementation","description":"\u003cp\u003eWritten by the creator of the OSPF (Open Shortest Path First) protocol, this book demonstrates the protocol in action with a complete OSPF implementation. It shows how the protocol's theory is realized in a real-time distributed software system, reveals many of the finer points of OSPF, and offers experienced-based optimization and porting techniques.\u003c\/p\u003e  \u003cp\u003eThe implementation described and examined in this book is written in C++ and designed with porting in mind. The book details the software architecture of the implementation and describes in-depth key OSPF functions, illustrated by numerous code samples. It also includes a guide to porting OSPF software to different environments, with an explanation of the software layer between the OSPF implementation and the operating system. In addition, two sample ports are included–a routing daemon for Linux and an OSPF routing simulator for Linux and Windows.\u003c\/p\u003e  \u003cp\u003eKey topics covered include:\u003c\/p\u003e  \u003cul\u003e  \u003cli\u003eImplementation architecture, including I\/O, data flow, and data structures\u003c\/li\u003e   \u003cli\u003ePorting considerations, including handling different types of CPU chips\u003c\/li\u003e   \u003cli\u003eAVL trees, Patricia trees, priority queues, timers, and logging messages\u003c\/li\u003e   \u003cli\u003eThe IP routing table\u003c\/li\u003e  \u003cli\u003eLink-state database, including aging LSAs\u003c\/li\u003e   \u003cli\u003eNeighbor discovery and the neighbor state machine\u003c\/li\u003e  \u003cli\u003eSynchronization of link-state databases through the flooding algorithm\u003c\/li\u003e   \u003cli\u003eHierarchy\u003c\/li\u003e   \u003cli\u003eRouting calculations, including intra-area, inter-area, and external routes\u003c\/li\u003e   \u003cli\u003eAn implementation of the Multicast Extensions to OSPF (MOSPF)\u003c\/li\u003e  \u003cli\u003eConfiguration and monitoring, including cryptographic authentication\u003c\/li\u003e   \u003cli\u003eHost wiretapping \u003c\/li\u003e \u003c\/ul\u003e  \u003cp\u003eTogether, \u003ci\u003e \u003cb\u003eOSPF: Anatomy of an Internet Routing Protocol\u003c\/b\u003e \u003c\/i\u003e and \u003cb\u003e \u003ci\u003eOSPF Complete Implementation\u003c\/i\u003e \u003c\/b\u003e provide an in-depth view into the theory and inner workings of OSPF, and the knowledge you need to make full use of this important protocol in Internet-based applications.\u003c\/p\u003e","brand":"Pearson Education","offers":[{"title":"Default Title","offer_id":47106452324592,"sku":"9780133757507","price":47.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0737\/7593\/9824\/files\/9780133757507_p0.jpg?v=1763642447","url":"https:\/\/shop-qa.barnesandnoble.com\/products\/9780133757507","provider":"Barnes \u0026 Noble (DEV)","version":"1.0","type":"link"}
