High Lean Service Provider Remote Control in Network Operation 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

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)

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

High Lean Service Provider 2 High Lean Service Provider 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

Operation Paradigm Shift Change of Telecom Business Environments Yesterday Today & near Future Network focus Service focus Circuit-based long-lived service (POTS) Session-based short-lived service (IP/Data Service) Reactive to customers Proactive to customers Relatively simple product mixture Increasingly complex product mixture Business driven by Telecom carriers and technologies Business driven by customers Mass marketing Target marketing

Business Agility TMForum NGOSS provide principle and tools for Telecom Business Agility

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

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

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 Application Architecture Technical 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

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)
