The Evolution of Telecom Management (Integration) Technologies 1980s SNMP 1990s CMIP, DCE (DME), CORBA, COM, RMI, to date HTTP, SOAP, WBEM, EJB, CORBA Components, ebxml, Workflow Automation.. What s next? WSDL,????
Technological Certainties Every few years there s another technological innovation for (management) systems Each innovation typically involves adherence to technology specific models and operating paradigms Resultant need to develop new technology skills whilst maintaining / enhancing existing management know-how! Will always need technology interworking
Trends in Component Based Development Driven by need for flexibility and software reuse Progress on common systems platforms for component ware EJB,.NET, CORBA Components Support growing range of integration technologies, RPC, message passing BUT true cost saving mainly come from buying more software as off the shelf components
Trends in Integration Technologies Management System technologies now merged with more mainstream distributed systems However: Technology churn shows no sign of slowing Can t escape the need for technology interworking Some improvements in insulating programmer from technology changes BUT each new technology seems to brings its own set of models
Integration Technologies Being Advocated today! XML/HTTP based Integration Enterprise Application Integration (EAI) Enterprise Java Beans Directory Enabled Networking so called fine grained management components) Workflow & Process Automation CORBA Components Policy Based Management
Management Platforms SNMP CORBA / EJB DMTF Agents Active Networks Each Platform tends to be allocated at different management layers or at least very specifice management problems
Management System Evolution Network perspective New Advance Service Type (wireless enabled) Pure IP Access Network Technology Multi Technology WDM/UMTS Gigabit Ethernet/Wireless LAN, Bluetooth
Advanced Services Highly Distributed Service Components Services hosted in Smart Devices (SIP Phone, PDAs etc) Browsing Email Gaming Video Conference Service Component Distribution IP Application Server Hosted Services (EJB, WebServices etc) Location Availability Presence Discussion Chat Voice Mail Messaging/SMS VoD/TV Radio Teleconference Centralized Service Components IN Type Services IVR SOAP, RMI, Event-oriented Low Real-Time Requirements Protocols Voice Telephony Multimedia streaming High Real-Time Requirements 3G APIs : SIP/OSA/PARLAY
Management Software Evolution Mainstream Software Evolution Java/EJB/CORBA Web based management services Development Process (RUP) Telecom Specific Software Evolution TMF SIM/BP/STA IETF SNMPv3 Policy based management
Potential Architectures for NGN Management systems Mobile Wireless Internet Forum (MWIF) TMForum NGOSS OSS through Java Model Driven Architectures (OMG/MDA) Meta-object Facility (OMG/MOF) XMI (XML based model interchange). 3G API s OSA (Open Service Access) Parlay Group JAIN
Management Projects subscribing to NGNI FORM : Traditional OSS : Reusable Components FAIN : Active IP Networks : Rapid Service Deployment/Reuse LION : Management / Signalling Interface for Optical Networks M31 : Mgt of Congestion/ Qos ANDROID : Programmable Network Elements : Shared Management Information Depaude : Software Framework/methodology
Management Clustering Management covers a very broad range of activities (network element to Enterprise model) Projects reflect this broad scope Convergence only exits at the information models and management component specifications.
Trials Service Interoperability Validation of API specifications Shared Information Models Platform Interoperability Small focused trials are more effective
