Informationen zum Autor Jean-Philippe Martin-Flatin is the author of Web-Based Management of IP Networks and Systems , published by Wiley. Klappentext The management of IP networks and systems is currently based on the Simple Network Management Protocol (SNMP) and the SNMP management architecture. This poses a number of problems some are related to the scalability and expressiveness of SNMP, others to the way the design of SNMP-based management platforms historically evolve.* Unique in showing the technical advantages of using Web-based management, and notably XML, in integrated enterprise management* Clearly explains the problems associated with SNMP-based management* Provides a wealth of technical tips and hints based on the author's industrial experienceEssential reading for all network designers, managers and researchers. Zusammenfassung The management of IP networks and systems is based on the Simple Network Management Protocol (SNMP) and the SNMP management architecture. This poses a number of problems some are related to the scalability and expressiveness of SNMP, others to the way the design of SNMP-based management platforms historically evolve. This work covers this subject.
