3 3 APNOMS2006, Busan, Korea Copyright ©2006 by KT NT Lab. All rights reserved. Copyright © 2006 by KT NT Lab. All rights reserved. Introduction Network operation & management until now –Network elements monitoring Massive alarm/performance data processing Standard management interface protocols (MIB) –SNMP, CMIP, TL/1, CORBA –Recently, Internet equipment life-cycle being very shorten then PSTN equipments. Vendors were focused on service capabilities then management interfaces NM related standards –NM standards release too lately then service capability standards –NM standards mainly focus on elements monitoring –Configuration & control interfaces are various NetConf, COPS, SNMP Vendor proprietary interfaces are more popular (ex. CLI) 11

Introduction Gap between SP requirements and standards & vendors implementations –Integrated of multiple technology networks vs. specific networks protocols –Multi-vendor standards vs. proprietary –Configuration and control vs. monitoring –Standard control interfaces vs. vendor proprietary console commands –Secure standards control interfaces vs. console Final goal of network management –End-to-end full automation Minimize manual operations only engage exceptional case –But AnalysisAnalysis work is very hard because very little information from network elements alarm signal (depends on manual analysis) Control or configurationControl or configuration works are acting by manual operations Monitoring Analysis (Root Cause Analysis) Control or Configuration and dispatches
