1 Telecommunications Working Group Dated June 23rd 2007 The information provided below is subject to change and reflects the current knowledge of the Working Group. Management Problem(s) and Environment With the application of many "high availability" techniques to the enterprise and the commoditization of many of the components traditionally considered part of telecommunications systems, the distinctions between telecommunications and enterprise markets are disappearing. In the past, the DMTF focused largely on the management of enterprise components (computer systems, local area networks, applications, etc.) but, in recognition of this market convergence, is extending its models and mechanisms to encompass the management of network elements, applications, networks and services in this converged computing world. The Telco WG is aiming to bring together collaboratively different standards both within and outside DMTF in the context of end-to-end service delivery to facilitate a common approach to management in a multi-technology environment. There are many benefits in having a standardized approach to delivering services in a converged network to the service provider, the end user of the service, the support systems providers, equipment manufacturers and system integrators. The results of this work will lower Service Provider s OSS implementation costs, and enable them to deliver superior SLA to their customers, increasing the customer satisfaction. This effort will allow for significant simplification and reduction of the development costs of interfaces and definition of new equipment, and incorporating new equipment into existing OSS. This represents a huge cost saving and a massive opportunity for equipment vendors to differentiate their equipment and services without requiring huge process change in the Service Provider. System Integrators also benefit from the work done by the Telco WG as a common approach across various standards enables them greater flexibility when providing solutions to their customers as well as opportunities in delivering new differentiated capabilities. The group is targeting to work with the owners of the particular management models and domains within and outside of DMTF to implement the necessary changes, enabling seamless end-to-end service delivery and management. Working Group Charter The Distributed Management Task Force (DMTF) has chartered the Telecommunications Workgroup with the following objectives:

2 1. Augment the existing CIM management models to encompass the components and services traditionally found, as well as emerging, in the telecommunications arena. The areas of immediate focus would be: a. Extension of the CIM models to cover telecommunications systems and services, creating appropriate class/property definitions to support important/ingrained telecommunications concepts, (e.g. Next Generation Transport Networks and IPTV Services) b. Liaising with other Work Groups to identify areas where the existing CIM models do not adequately cover telecommunications networks and network devices and to prioritize the development of these models using resources from either Work Group (or elsewhere). The final owner of such network models would be the Telco Work Group. c. Support the adequate coverage by the CIM model of the standard telecommunications-grade programmatic interfaces for intelligent hardware management (e.g. Hardware Platform Interface (HPI), see 2. Facilitate enhancements to DMTF Management Architecture to enable ease of integration of DMTF management components into Service Providers Operation Support Systems (OSS). Define the access to the DMTF management components and services in such a way as to support the resilience necessary for operating a highly available system (e.g., automated roll-back, transactional command sets). The results of this work are of wider interest than the Telecommunications Work Group and such work will be done in conjunction with the Infrastructure Sub-Committee, Schema and other DMTF Sub-Committees and Workgroups as appropriate. 3. Facilitate the work on Harmonization of Common Information Model (CIM) and Management Interfaces developed and maintained by DMTF with Information and Data Models developed by other Standards Development Organizations (SDO) in the context of end-to-end service delivery and management (International Telecommunication Union (ITU- T), TM Forum, 3 rd Generation Partnership Project (3GPP), Internet Engineering Task Force (IETF) specifically related to NetConf Management Protocol, Service Availability Forum (SAF), etc.). This work will be done as a joint effort between this workgroup and similar workgroups in peer organizations and in conjunction with other DMTF Workgroups. 4. Collect and prioritize use cases, model resources and services required to support Service Providers operations.

3 5. Establish profiles for the above modeling efforts in order to establish extensible schemata that meet the known requirements of today s and future industry implementations. 6. Work in conjunction with the following DMTF working groups as appropriate to develop common models and protocols related to highlyavailable telecommunications concepts. These currently include: a. Infrastructure Sub-Committee and its Workgroups c. System Virtualization, Partitioning, and Clustering Work Group (SVPC) d. Platform Profiles Work Group e. Schema Sub-Committee Alliance Partnerships TeleManagement Forum (TM Forum). TM Forum is the world s leading trade association that provides leadership & guidance, technical & business innovation, and education & training to improve the way telecoms, media and information services are created, delivered, assured and charged. More information on the joint work between DMTF and the TMF can be found in the work register located at: Service Availability Forum (SAF). The Service Availability Forum is a consortium of industry-leading communications and computing companies working together to develop and publish high availability and management software interface specifications. The SA Forum then promotes and facilitates specification adoption by the industry. ITU-T: Next Generation Network Management Focus Group (NGNMFG). The NGN Management Focus Group was established to organize and undertake a centralized approach regarding specification of NGN management related to FCAPS interfaces. By FCAPS is meant Fault, Configuration, Accounting, Performance, and Security Management and within the ITU-T the phrase "FCAPS interfaces" generally includes NE-OS, OS-OS, and NE/OS-WS interfaces in support of element, network, service, and business management. Other alliances with telecommunications organizations may be created in the future. Reliance/Coordination with other WG Models The Telecommunications Work Group is dependent on and will work close with the Infrastructure Sub-committee Work Groups in the areas of basic architectural concepts and principles, management protocols and meta-models. It is expected that the members of relevant WG may be involved into various activities of the

4 Telco WG in order to ensure architectural consistency across various specifications. The Telecommunications Work Group will rely on the Schema Sub-Committee in support for required changes and evolution of the existing CIM schema. The Telecommunications WG targets to develop and maintain the resource profiles to support service-delivery oriented views of the transport networks (IP, Ethernet, MPLS, PBB-TE, SDH, PDH) and work with the Physical Platform Profiles WG to augment existing network profiles The Telecommunications Work Group is dependent on the Systems Virtualization, Partitioning and Clustering work group for the definitions of cluster profiles and related CIM model objects. It is also dependent on the System Management Architecture for Server Hardware (SMASH) initiative and the Server Management Work Group for the definitions of hardware-centric server and blade specific profiles and CIM model objects. Instances of those hardware-centric objects may be referenced in the SVCP WG as cluster-aware server resources are modeled. The Telecommunications Work Group may depend on underlying profiles being developed by the Platform Profiles Work Group. Prior Work CRs for Alarm Management, Entity Modeling, and Metrics; Service Availability Forum Application Interface and Application Management Framework Model. Current Work Overview, Deliverables and Timeline The Telecommunications Working Group has the objective of producing a number of specifications, describing use cases, reference models, interoperable profiles and sub profiles with the focus on a common approach to management and service delivery in converged multi-technology environment. The specific deliverables, in priority order, being developed are: - CIM-HPI mapping guideline. The mapping guideline is intended to provide HPI and CIM developers a clear understanding on how integrate a CIM provider to HPI. Additionally the mapping exercise will identify system management domains of the CIM Schema not fully representative of those areas covered by HPI and will drive changes to the schema. - Whitepaper on Justification of Management Architecture/Model Harmonization between DMTF and TMF. - CIM/SID Mapping Methodology Specification. The Mapping Methodology Specification was jointly developed by DMTF and TMF during the second phase of CIM/SID harmonization work. Currently it is necessary to complete the review by DMTF members parallel to TMF member review.

5 - IPTV Services Management Profiles. The target of this work is to create management profile describing transport network resources and services in technology neutral manner in order to support variety of IPTV Services. The profile specification will also include a subset of Use Cases and models for the customer-facing IPTV Services. - IPTV Service Management standards analysis. In order to position correctly the modeling work in the area of IPTV Service Management it is necessary to analyze the existing work already done by the industry groups. The specification produced by various standard bodies need to be collected and analyzed for semantic and implementation similarities and the gaps need to be identified. As a result this work should provide a direction to the Working Group where to go and what to focus on first in terms of more specific modeling of customer-facing IPTV Services. - Management Interface harmonization (WS-Man, mtoss/j, OASIS). In order to support plug and play architectures of Service Provider s OSS it is necessary to harmonize management interfaces developed by different standard bodies. The Working Group members will participate in various harmonization activities between DMTF and other industry groups, will make their contribution and carry results into other DMTF Working Groups as this work may affect overall DMTF Management Architecture. - Networking Profiles (e.g. IP Topology Profile, VLAN Profile, MPLS Network Profile, etc.). - Resource naming. There is a gap between CIM and other standards resource naming paradigms. The Working Group should analyze and close such gaps wherever possible as a part of overall industry architecture and model harmonization effort. - Alarm information harmonization (ITU (X.733), TMF, and DMTF). There are differences between DMTF and other standards in definition of Alarm Information. The Working Group should contribute to overall industry harmonization by analyzing the differences and closing such gaps between DMTF models and other models wherever possible. - Development of the modeling patterns and templates in CIM in addition to the management profiles. This work will come out as an architectural contribution to the CIM model from the Harmonization work the Working Group takes part in. Note that the output from this working group is not a "telecommunications submodel" since that would not reflect the convergence within the industry: rather these models are integrated into the existing models, building a converged system reflecting industrial reality.
