高级网络管理（影印版）

　　《高级网络管理（影印版）》由Steve Wisniewski著，Despite all the advances in technology，the old reliable architectures and protocolsare still being implemented in the internetworking arena today because they haveproven tO be reliable and have worked with many different products．Advanced Net-work Administration covers the concepts of routing，bridging，switching，and networkmanagement．This book iS recommended for novices who wish to further their knowl-edge ofinternetwork design．Chapters 1-3，OSI InternetworkingBasics，BridgingandSwitchingFundamentah，andRoutingBasics，shouldbetaughtas aunit．Chapters4 and5 cover Network ManagementFundamentals and Simple Network Management Proto-col．From Chapters 6 to 10，each of the main network architectures，along with thevarious protocols that comprise these architectures．are exposed．Chapters 11 and 12depart from the architectural viewpoint and discuss／nterdomain Routing Basics．OpenShortest Path First，explained in Chapter 11（OSPF），and Border Gateway Protocol，discussed in Chapter 12（BGP），are the main protocols being used in the Internet toprovide reliable routing from host to host．These two chapters should be tau#t as aunit．Chapter 1 3，Advanced IP Routing，provides a brief explanation of IP addressingand more advanced concepts such as VLSM andⅥANS，along with route summarization and redistribution．For a more thorough explanation on IP addressing refer toChapter 9，Digital Network Architecture（DNA）DEcnCt Phase IV.Chapter 14 discusses Data Link Protocols and their importance in internet-working．Chapter 15，Internetworking Design Basics，is the capstone chapter dis-cussing how to design an internetwork using routmg and switching methods.

　　Steve Wsniewski is currently working as a computer telephony engineer for Greenwich Technology Partners and has been in the internetworking and networking industry ofr more than 12 years.He is a 1972 Graduate of Marshall university，a 1995 graduate of De Vry Technical Institute，and has earned a master of science deree in telecommunications management from the Stevens Institute of Technology.
