  • The SOA/WS management community has a problem:

    • Insufficient # and range of standardized resource models

  • Correctly converted SNMP MIBs can help to solve that problem:

    • Standardized, numerous, multi-domain, instrumented

  • The IETF O&M community is the right group to lead that effort:

    • Expertise, continuity, authority, control

Development of a Standard Methodology for Converting SNMP MIBs to Resource Models for the SOA/Web Services Management Environment (MIB2RMDL)

Problem opportunity description 1

Problem/Opportunity Description - 1

  • The SOA/WS management community lacks a critical mass of standardized data models in appropriate formats to deliver acceptable solutions to the (waiting) user community.

  • The existing body of IETF SNMP MIBs can fill a major portion of that gap very quickly if they are converted to appropriate SOA/WS “resource model” artifacts.

  • The IETF should take the lead in standardizing the methodology for converting SNMP MIBs to SOA/WS resource model artifacts.

  • The IETF might also consider making reference implementation tools freely available (in a manner similar to xml2rfc).

Problem opportunity description 2

Problem /Opportunity Description - 2

  • Emerging SOA/WS management solutions face some major near-term limitations:

    • Lack of standardized “resource models”, esp. for node and network management.

    • Little desire among vendors to incorporate SNMP into their products.

    • Strong desire among operators for a unified management solution, emanating from the service management perspective.

  • The existing (and future) body of SNMP MIBs is an unequalled set of proven data models for node, network, and application management.

  • Managed object instrumentation supported by those SNMP MIBs can be made more readily accessible to SOA/WS management solutions at relatively little cost and with substantial benefit to all stakeholders.

Primary goal is to standardize theMIB2RMDL conversion methodologyto provide greater management coveragefrom the SOA/WS management service bymaking instrumentation via SNMP agentstransparently available via SOA/WSresource models.

Potential beneficiaries benefits

Potential Beneficiaries & Benefits

  • SOA/WS Management vendors

    • More appealing products to offer

    • No need to reinvent the wheel wrt SNMP MIB data models or instrumentation

  • SNMP-managed equipment vendors

    • Broader market for existing products w/o code changes

  • SNMP Management vendors

    • Supply MIB2RMDL conversion/validation tools

    • Supply WS/SNMP proxy solution

    • Eventually supply SOA/WS instrumentation in existing SNMP-managed NEP products

  • SOA/WS Management user community

    • More unified management solutions from the service layer

    • Fewer distinct management tools to have to purchase, operate, and correlate

Background 1 some starting points

Background – 1Some starting points

  • Work on SNMP MIB to XML conversion is a solid start on a necessary part of the solution.

  • XML alone is not sufficient because the SOA/WS management approach requires:

    • More extensive (structured) description of manageable resources

    • Modular packaging of descriptive elements

  • Apache Muse open source project (WSDM) can help guide this work and test outputs

  • Eclipse COSMOS (resource modeling) open source project can help guide this work and test outputs

  • MIB2XML, SMIng, NETCONF, XCAP, etc., provide likely sources of relevant IETF expertise.

Discussed next

Background – 2Candidate resource model artifacts

  • XML (eXtensible Markup Language)

  • RDF (Resource Description Framework)

  • WSDL (Web Services Description Language)

  • WS-Addressing (Web Services Addressing spec)

  • WS-Policy (Web Services Policy specs)

    • Including WS-Security related specs

  • WS-CIM (Common Information Model)

  • SML (Service Modeling Language)

  • CML (Common Model Library)

  • OWL-S (Ontology Web Language - Services)

Proposal

This is a proposal for the IETF O&M Area to take on a defined task, with concrete near-term deliverables that have utility and value for the broader O&M community.

It is somewhat atypical of our historical efforts, but not without direct precedent, and positions the Area to be a leader in forward-looking network management solutions.

Proposal

  • The IETF O&M Area should take the lead on development of a standard methodology for converting SNMP MIBs to SOA/WS management resource model artifacts.

  • This effort should leverage the Apache Muse and the Eclipse COSMOS projects for resource model artifact selection and testing/verification of conversion outputs.

Comments received

Comments Received

  • Mark Ellison:

    • General editorial help

  • CA:

    • Positive; consider WS-CIM

  • IBM:

    • Positive; emphasize XSD basis; leverage Apache Muse and Eclipse COSMOS; produce directly usable artifacts

  • Juergen Schoenwaelder:

    • Clearly define what is needed by the SOA/WS mgmt community; clearly define benefits for stakeholders; questions reference to SNMPv3 security in the Draft

  • Andy Bierman:

    • Clarify API status; leverage and/or support NETCONF; concerns about “proxy use case; points to CLI use case (in contrast)

  • Dan Romascanu:

    • IETF relevance; SOA/WS terminology; concerns about tools as IETF outputs

Next steps

Next Steps

  • Wait for SOA/WS marketplace to finalize resource modeling decisions?

    • Might complicate life for eventual MIB2RMDL conversion methodology

    • Might ignore IETF (O&M and broader) requirements and conventions

  • Take the lead (recommended):

    • Form IETF O&M Area WG to standardize the MIB2RMDL methodology

      • Specifications

      • Reference implementation tools (optional)

    • Collaborate with NMRG on fast-track applied R&D

    • Leverage and guide related industry open source efforts (Eclipse COSMOS and Apache Muse)
