3. Introduction 1 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)

4. Control or Configuration
Introduction
Gap between SP requirements and standards & vendor’s implementations
Integrated of multiple technology networks vs. specific network’s 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
Analysis work is very hard because very little information from network element’s alarm signal (depends on manual analysis)
Control or configuration works are acting by manual operations
Monitoring
Analysis
(Root Cause Analysis)
Control or Configuration
and dispatches

11. Enterprise-wide Process
All kind of control process should be defined to the enterprise-wide process
From customer’s service request (new/change)
Service/network provisioning
From customer’s service complain
From network fault/performance degradation
Should be managed by BPM system and Policy rule

12. Customer Self-service Management
Customer Network Management

Equipment vendors consider monitoring interface only.
Very few control interfaces
Vendor’s proprietary implementation
Very hard to implementation of generic control functions for service provider
No firm standard control interface !!
More important in NGN, FMC (All-IP) era

TAM
* EA : Suggestion by Zachman (IBM), TMForum’s NGOSS is best EA case in Telecommunication Industry

21. Business Architecture
Business Process and function separation
Business process are vary change
New service or change of business are very often
Definition of end-to-end enterprise business process are very difficult
Should be upgrade during in operation
If IT system implemented by hard-coded business process, it will be very cost and slow
Business Policy/Rules are very important
Business rule enable a giant leap forward in bridging the gap between business people and IT system
Business policy/rules are operation know-how
Industry standard business process : TMForum eTOM
COTS interoperable IT environments
Standard business process description language : WS-BPEL (Business Process Execution Language)
Process Optimization by BAM (Business Activities Monitoring)

30. Remarks 7 More Intelligence on Network Resource Management
Define Enterprise-wide network resource management processes
Resource Trouble/Performance/Provisioning Management
Introduce BPM tool in NMS
Operator’s know-how translate to the policy/rule
Define and refine the business rule for through all Resource and Service Management
Root Cause Analysis method
Control mechanism as different vendor or different case
Introduce RBMS tool in NMS
Standardization of network control interface
More important on All-IP networks but less standardization and implementation
Service providers should be initiator for global standard
