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 int

erfaces 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)

1111


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• AnalysisAnalysis work is very hard because very little information from network element’s

alarm signal (depends on manual analysis)• Control or configurationControl 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


Customer Self-service Management

Customer Network Management– Service status monitoring for customer services

Customer Service Order Request/Change Customer Service Complain


Remote Control in Network Operation3333

Define of remote control Control in Trouble & Performance

Management Processes Type of Control

– Traffic Control• PSTN Traffic Control• MPLS TE Control

– Activation/De-activation


Define of Remote Control

Not signaling control– No.7 Signaling, UNI signaling, OCP, NCP …

Network elements (include service servers) control/configuration for network maintenance– Resource provisioning

• Activation/deactivation

• Resource (NE) configuration

– Trouble shooting• Protection, restoration, resolve

– Performance control• Traffic control

– Environment control• Power system, air-conditioning, security

Type of Control Network Control

– Traffic/Performance Control• PSTN LEX RC• MPLS TE control by CLI (Command Line Interface)• Policy Control by COPS (Common Open Policy Services)

– Routing Control• Routing Table update• Optical Cross Connect control

– Service server control• DNS, DHCP policy control• Application servers policy control

– Activation/deactivation/configuration Environments Control

– Power, battery– Air conditioning (temperature, humidity)– Security control (manless offices, Mobile base station door and so o

n)


Control/Configuration Interface standards IETF

– Netconf– SNMP V3/SMI V2– COPS

ITU-T– M.3000 Series– X.700 CMIP/CMIS

TMForum– TMF509

DMTF– CIM/WBEM

3GPP, ATIS, OMA, MSF, ….. 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

Architecture


Service Provider’s EA

Define the Enterprise Architecture (EA*) for enterprise control/management

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

Business Architecture Data Architecture

Application Architecture Technical Architecture

Define integrated and industry-agreed business process for end-to-end automation

Events, Business rule Identify all functional entities through each business process

eTOM

Mapping functions to the applications

Define the whole applications in company as reference model for system develop

TAM

Define the principle of Contract and interactions

Define basic framework services.Define the implementation principles

re

standardized information definitions acting as the common language

A common information language is the linchpin in creating easy-to-integrate software solutions.

SID


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)

Evolving NeOSS Intelligent Control enabled NMSs

– Define Standard unified Control/Configuration– End-to-end process automation

• From service management to network element control• Network element’s alarm/info to service quality management

Business Performance Management– Real-time business activities monitoring– Finding and diagnostic bottle-neck process point– Real-time process innovation

Field Know-how to the Business Rule– Rule based RCA (Root Cause Analysis), trouble-shooting, performan

ce control

All-IP Converged Network/Service Manageability– Mobility Management, Session Management– QoS Management across various networks (WCDMA, WiBro, MPLS,

IMS)

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
