Future Direction of Network and Service Management

1. Future Direction of Network and Service Management Yoon Hak Bang KT Network Technology Lab.

2. Introduction High Lean Service Provider Remote Control in Network Operation Control/Configuration Interface standards Resource & Service Management Architecture KT’s Direction Remarks 1 C O N T E N T S 2 3 4 5 6 7

3. 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)

4. 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

5. Operation Paradigm Shift Business Agility Reduce the OPEX !! Resource vs. Employee End-to-end Process Automation Inter-domain management Automatic Network Elements Control Enterprise-wide Business Process Management Customer Self-Service Management 2 High Lean Service Provider

6. Operation Paradigm Shift • Change of Telecom Business Environments Yesterday Today & near Future

7. Business Agility • TMForum NGOSS provide principle and tools for Telecom Business Agility

8. Decreasing the Operational Staff Reduced the OPEX !!! • Resource vs. Employee New Service Request 160 20 18 140 152 100 million KW) 16 120 14 100 ( 12 Request 10 80 62 Budget 8 60 6 40 4 18 20 2 0 0 2002 2003 2004 budget request Operational efficiency is needed More requests, faster development is needed

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 • Service status monitoring for customer services • Customer Service Order Request/Change • Customer Service Complain

13. Define of remote control Control in Trouble & Performance Management Processes Type of Control Traffic Control PSTN Traffic Control MPLS TE Control Activation/De-activation 3 Remote Control in Network Operation

14. 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

17. 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 on)

18. 4 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

19. Service Provider’s EA Business Architecture Data Architecture Application Architecture Technical Architecture Agility Enabled Network Management Architecture Resource & Service Management Architecture 5

20. Service Provider’s EA • Define the Enterprise Architecture (EA*) for enterprise control/management Business Architecture Data 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 • standardized information definitions acting as the common language • A common information language is the linchpin in creating easy-to-integrate software solutions. • SID Telecom Service Provider’s Enterprise Architecture Technical Architecture Application Architecture • Define the principle of Contract and interactions • Define basic framework services. • Define the implementation principles • TNA • Mapping functions to the applications • Define the whole applications in company as reference model for system develop • 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)

22. NGN (BcN) Service Planning Network Infrastructure Network Management Premium Internet WiBro WCDMA Internet xDSL/FTTH/WiFi PSTN Leased-line ATM/FR SDH/PDH Data Architecture • Very important in interface definitions • Common language between different department in company or B-to-B NMS Sales Customer Care Service Configuration Service Problem Service Quality Resource Provisioning Resource Trouble Resource Performance Network Elements Adaptation
