1 DMTF TELCO WORKING GROUP ON CLOUD MANAGEMENT AND VIRTUAL NETWORK Alex Zhdankin, Cisco Systems

2 TELCO AND NETWORKS WG THE AIM AND PURPOSE There is an increasing demand to provide unified management for the network protocols layers and services which can be used to manage both the traditional the new Virtual Networks Implementers and Solutions Providers using DMTF CIMbased solutions require integration into a mature OSS/BSS tool set mapping of new management solutions into existing NMS systems architecture Many of the DMTF efforts, addressing the Cloud and Virtual Network management space today are focused on L2 with modeling and profile efforts stopping at the Ethernet Port or Switch Telco & Networks WG is aiming to provide significant simplification and reduction of costs associated with implementation of the management solutions addressing the Network and System administration demands to manage any virtual IAAS, PAAS or SAAS solutions

3 TELCO WG AND VIRTUALIZATION In the emerging Virtual Network and the Cloud IAAS technologies there is a shift from hardware (appliances, physical routers and switches etc.) to software based network devices and services (Virtual Appliances and Virtual Machines) This shift has strained the legacy semantics and syntax in use in traditional network management architectures and solutions The Telco and Networks WG s efforts will seek to unify this disparity and provide common management methodologies and profiles The work is built in most cases on the prior work done in other WGs or by extending the work underway and chartered in other WGs

4 TELCO WG AND CROSS-INDUSTRY COLLABORATION The WG aims to coordinate the work around development and adoption of the standards for the cloud computing environment To prevent the divergence of information models, management interfaces, protocols and metrics used for the cloud computing management Industry divergence in the management area drives development, integration and operational costs up For this reason, equipment vendors, service providers and enterprises will benefit from this work Customers and vendors of different organizations benefit from this effort by having consistent information models, management interfaces, protocols and metrics used for the cloud computing management from technology through business perspectives Combined work will provide a stronger basis for application interoperability and co-existence and will allow to lower development, integration and operational costs As a part of ongoing working relationships between TM Forum and DMTF there is a recently established liaison, focusing on harmonization of management standards in the area of Cloud Computing

5 DMTF CONTRIBUTION TO LIAISON Cloud reference architecture Use cases including service catalog interactions Virtualization resource models and OVF Networking requirements specifications Virtual Network use cases for OVF extension Storage (via SNIA alliance) requirements for virtual servers and OVF images Security (via CSA alliance) requirements for virtual servers/images Computing platforms and storage resource metrics

6 TM FORUM CONTRIBUTION TO LIAISON Service Delivery Framework (reference model and use cases) Integration Contracts/Business Services and other frameworks: Business Process Framework (etom) harmonized with ITIL Information Framework (SID) Customer experience and e-2-e application performance (SLA/SLO and metrics) Network performance metrics/kpis Transport network models Ethernet Service Management Service Catalog interactions from Cloud Catalyst experience Reference Architecture for hybrid / stateless cloud environment from ECBC

7 EXPECTED RESULTS OF THE JOINT WORK Network virtualization the location-aware cloud services ability to represent a cloud service and have its networking requirements specified and provisioned Info/data model harmonization continuation of the effort Bridge between metrics (e.g. SLAs from TM Forum to SLOs for IT resources) to allow proper resource allocation and Service Quality/Customer Experience assurance Monitoring and reporting on the SLAs based on resource utilization Cloud-centric specialization for metrics and integration contracts To ensure lifecycle of cloud service from subscription to fulfillment and assurance Converged/harmonized security model specialized for the Cloud
