{"product_id":"9780321618931","title":"NFS Illustrated: Network File Sys Illus_c1","description":"\u003cp\u003eThe Network File System (NFS) protocol that enables remote access to files is now a key element of any LAN. It is also currently and increasingly used as a key technology with the Web and wide area networks.\u003c\/p\u003e \u003cp\u003e \u003c\/p\u003e \u003cp\u003eWritten for programmers creating NFS-based applications, network engineers creating new implementations of NFS, and network managers, \u003ci\u003eNFS Illustrated\u003c\/i\u003e promotes a thorough understanding of that protocol through extensive diagrams and real protocol traces that show NFS in action. Covering NFS versions 2 and 3, the book also looks into WebNFS and the new NFS version 4, with Internet support. Detailed and authoritative, the book not only examines NFS in depth, but also describes the protocols that underlie and support it, including External Data Representation (XDR), Remote Procedure Call (RPC), the NFS MOUNT protocol, and the NFS Lock Manager protocol. It discusses several NFS variants and compares NFS to a number of alternative file systems. \u003c\/p\u003e \u003cp\u003e \u003c\/p\u003e \u003cp\u003e You will find a detailed discussion on the NFS filesystem model and a procedure-by-procedure description of NFS versions 2 and 3, illustrated through the use of snoop traces that capture and display protocol packets from the network. In addition, the book addresses real-world implementation issues faced by those building an NFS client or server, factors that affect NFS performance, and critical performance benchmarks. \u003c\/p\u003e \u003cp\u003e \u003c\/p\u003e \u003cp\u003e Specific topics of interest include: \u003c\/p\u003e \u003cul\u003e \u003cli\u003eNFS version 4, highlighting performance improvements, security features, and cross-platform interoperability for Internet operation \u003c\/li\u003e \u003cli\u003eRPC authentication and security \u003c\/li\u003e \u003cli\u003eDifferences between NFS versions 2 and 3 \u003c\/li\u003e \u003cli\u003eImplementation issues for clients and servers \u003c\/li\u003e \u003cli\u003eRead-ahead and write-behind \u003c\/li\u003e \u003cli\u003eCaching policies \u003c\/li\u003e \u003cli\u003eThe Lock Manager protocol \u003c\/li\u003e \u003cli\u003eAutomounting \u003c\/li\u003e \u003cli\u003eNFS variants, including Spritely NFS, NQNFS, Trusted NFS, and NASD NFS \u003c\/li\u003e \u003cli\u003eNFS competitors: RFS, AFS, DCE\/DFS, and CIFS \u003c\/li\u003e \u003cli\u003eThe PCNFS protocol for implementing NFS on PC operating systems \u003c\/li\u003e \u003cli\u003eSPEC SFS benchmarks, WebNFS, and firewalls \u003c\/li\u003e \u003c\/ul\u003e \u003cp\u003eComprehensive and current, \u003ci\u003eNFS Illustrated\u003c\/i\u003e is an essential resource for network professionals who want to use this widespread and evolving technology to its fullest.\u003c\/p\u003e","brand":"Pearson Education","offers":[{"title":"Default Title","offer_id":47102598775024,"sku":"9780321618931","price":39.95,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0737\/7593\/9824\/files\/9780321618931_p0.jpg?v=1763682451","url":"https:\/\/shop-qa.barnesandnoble.com\/products\/9780321618931","provider":"Barnes \u0026 Noble (DEV)","version":"1.0","type":"link"}
