1 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)

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
Monitoring
Analysis
(Root Cause Analysis)
Control or
Configuration
and dispatches
– 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

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

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)

7 Remarks

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
