  • Cisco Confidential 14 2013 Cisco and/or its affiliates. All rights reserved.

    The revolution began with the recognition that the divergence era is unsupportable:

    Duplication of infrastructure

    Duplication of support (NOC)

    During this period, traffic types and characteristics have been examined and new solutions to the divergence problem have evolved:

    DQDB

    SMDS

    ATM

    IP (with QoS)

    IP is generally accepted as the network-convergence technique of choice.

    An NGN is:

    A packet-based network able to provide telecommunication services, and able to make use of multiple broadband and QoS-enabled transport technologies, in which service-related functions are independent from underlying transport-related technologies.

    The NGN offers unfettered access for users to networks and to competing service providers and/or services of their choice and supports generalized mobility that will allow consistent and ubiquitous provision of services to users.

    Characteristics:

    NGN is an IP-based network

    NGN enables any IP access from mobile, home, and/or enterprise domains

    NGN enables service mobility

    NGN enables interworking toward circuit-switched voice

    NGN maintains service operator control

    One burst of every TDMA frame was sufficient to transport a speech frame with source rate of 13 kbit/s

    GSM Phase 2 (circa 1996) added Circuit Switched Data support offering 9.6 kbit/s service

    Context Business process framework for SPs

    Products (services) to their customers,

    consumer internally of ITIL services

    Concentrates on IT service mgmt,

    independent of the business or industry

    sector

    Objectives Provides a business process blueprint for

    SPs to streamline their end-to-end

    processes

    Enables effective communications and

    common vocabularies within the SP and

    with customers and supplier

    Aligns IT services with current and future

    needs of business and customer

    Improves the quality of IT services

    delivered

    Reduces long-term cost of service

    provision

    Scope Provides a top-down hierarchical view of

    business processes across the SP

    Focuses on identifying commonality among

    processes for similar services (e.g.,

    telephony, HSD, mobiles)

    Focuses on service delivery to external

    customers

    Represents flows in a number of key

    operational areas

    Offers advice/guidance on the

    implementation and continued delivery of

    Focuses on serving internal IT customers

    eTOM ITIL

    Adoption Adopted by ITU International

    Standards for the Telecom Sector

    and used by many SPs

    Used as a set of best practices by over

    10,000 companies including some SPs

    Used by many SPs for incident

    management and service desks

    Implementation Implemented differently by each SP

    as it is a framework

    Supported by TMF/NGOSS

    specifications

    Also a framework

    Provides implementation guidelines in

    v3 as earlier versions did not provide

    guidelines or ways to assess maturity

    Compliance Achieved through the TMF/NGOSS

    Compliance Program with

    certification on tools, not on

    organizations and processes

    No such thing as ITIL compliant as ITIL is not a standard nor a set of

    regulations. Processes and

    organizations, not tools, can be

    assessed and certified against ISO/BS

    15000, the IT Service Management

    Standard based on ITIL.

  • Cisco Confidential 89 2013 Cisco and/or its affiliates. All rights reserved.

    TMF/eTOM team formed in mid-2004 to develop guidelines to relate the two programs

    Provide information on mapping from one view to the other

    Focus initially on the ITIL incident management area

    Published a TMF Technical Report, An Interpreters Guide for eTOM and ITIL Practitioners

    Terminology comparisons

    Mapping between processes

    Business benefits of a combined approach

    Published TMF TR 143, Building Bridges: ITIL and eTOM (August 2008)

    SPs able to show compliance with ITIL without using the ITIL processes

    Frameworks are complementary

    ITIL moved from government support to IT Service Management Forum (ITSMF)

    Push to formalize ITIL from its current set of loose and sometimes inconsistent verbal definitions

    Drive for convergence with the TMF NGOSS community

    Projected in 2005 that ITIL would be more consistent, formal, and better fitted to support operational management technologies in a year (changes did not happen)

    Reality is that some knowledge of eTOM is likely required to talk with SPs

    You will see ITIL processes for service operation

    ITIL processes will be mapped within eTOM

    SPs will be conversant in eTOM

    ITIL is NOT just for enterprise
