to the OGF are subject to all provisions of Appendix B of GFD-C.1, which grants to the OGF and its participants certain licenses and rights in such statements. Such statements include verbal statements in OGF meetings, as well as written and electronic communications made at any time or place, which are addressed to:

• the OGF plenary session, • any OGF working group or portion thereof, • the OGF Board of Directors, the GFSG, or any member thereof on behalf of the OGF, • the ADCOM, or any member thereof on behalf of the ADCOM, • any OGF mailing list, including any group list, or any other list functioning under OGF auspices, • the OGF Editor or the document authoring and review process

• Statements made outside of a OGF meeting, mailing list or other function, that are clearly not intended to be input to an OGF activity, group or function, are not subject to these provisions.

• Excerpt from Appendix B of GFD-C.1: ”Where the OGF knows of rights, or claimed rights, the OGF secretariat shall attempt to obtain from the claimant of such rights, a written assurance that upon approval by the GFSG of the relevant OGF document(s), any party will be able to obtain the right to implement, use and distribute the technology or works when implementing, using or distributing technology based upon the specific specification(s) under openly specified, reasonable, non-discriminatory terms. The working group or research group proposing the use of the technology with respect to which the proprietary rights are claimed may assist the OGF secretariat in this effort. The results of this procedure shall not affect advancement of document, except that the GFSG may defer approval where a delay may facilitate the obtaining of such assurances. The results will, however, be recorded by the OGF Secretariat, and made available. The GFSG may also direct that a summary of the results be included in any GFD published containing the specification.”

• OGF Intellectual Property Policies are adapted from the IETF Intellectual Property Policies that support the Internet Standards Process.

The problem area

Working Group Drivers

Hybrid networks offer end users combinations of packet-based IP services and circuit-oriented services

DMNR focuses on circuit-oriented services and how they are provided across networks in different administrative domains.

Working Group Drivers

Where paths traverse more than one administrative or technology domain, the allocation of resources required to provision these lightpaths must be negotiated and agreed between domains.

To do this dynamically requires a control plane interaction to create and share a topology between domains, to request and signal circuits, and federated user authentication/authorization of resources required for the authorization of circuit requests and the assignment of network resources

Working Group Objective

Combine efforts of multiple projects to specify an interdomain interface and protocol for network resource management, including standardised network topology exchange and resource scheduling, thus facilitating interoperability between different projects

Presentations

• John Vollbrecht - DICE-CP (IDC)

• Inder Monga - IDC development for DRAC

Deliverables: D1 A recommendation document describing an architecture for

DMNR between domains, may include:• A diagram defining control plane and data plane interfaces

relevant to working group• A list of the protocols relevant to these interfaces and a

definition of which are defined here• Terminology/definitions• Message propagation model: tree/chain• Hierarchies and topology abstraction principles• Identify an AAA model (how about policies?)• Path computation • Associated lookup service requirements

Deliverables: D2 A recommendation document describing a protocol or

set of protocols required to achieve Dynamic Resource Management.

• Topology exchange messaging• Path reservation creation/ modification/ removal

messaging• Path signalling messaging• Path monitoring messaging• Path keep-alive messaging

Wrap up• Nominations for WG chairs• Action points• Next meeting
