IPO Meeting Minutes:

IETF IP Over Optical WG (ipo)

Tuesday, March 19th at 1545-1645
===================================

CHAIRS: Jim Luciani ([email-masked])
        Daniel Awduche ([email-masked])

The following topics were discussed during the meeting:
1. Jim Luciani: Introduction,
2. Ong, "Optical Inter Domain Routing Considerations,"
     draft-ietf-ipo-optical-inter-domain-01.txt,
3. Yong Xue, "Carrier Optical Services Requirements",
    draft-ietf-ipo-carrier-requirements-01.txt,
4. Osama Aboul-Magd, "Automatic Switched Optical Network (ASON)
   Architecture and Its Related Protocols,"
   draft-ietf-ipo-ason-02.txt,
5. Kohei Shlomoto, "Requirements of optical link-state information
   for traffic engineering", draft-oki-ipo-optlink-req-00.txt,
6. Closing: Dan Awduche,

1. The meeting commenced with an overview of the IPO WG
   status provided by Jim Luciani:
 - The following are pending items that will be removed from the charter
 - Traffic engineering aspects
 - Requirements for distribution of topology state information

------

2. draft-ietf-ipo-optical-inter-domain-01.txt -- presented by Ong
 - Jim Luciani indicated there are controversies concerning
   this work.
 - Ong stated the document is now half the original size.
 - Protocol specific aspects have been removed.
 - A stronger distinction has been made between inter-domain
   and intra-domain
 - BGP inter-domain protocol, but does not consider diversity
 - Closely related to OIF NNI
 - Study group 15, to define G.7715 (routing specifications,
   protocol independent aspects)
 - Question from Yong Xue -- work conflicts with ITU-T G.DCM, any
   prospects to continue this activity in the IPO WG? -- Jim Luciani
   responded -- need to take issue to mailing list. WG chairs need to
   adjucate.
 - Question from audience - overlap with OIF NNI -- is there any
  coordination. Answer - the work in the OIF is still very preliminary

------
3. draft-ietf-ipo-carrier-requirements-01.txt, present by Yong

 - gave an overview of the present status of the document
 - two goals -- set of services from IPO networks
 - set of requirements from control plane to support service models
 - changes from last version -- significant editorial work
   to remove redundancy and increase readability of document
 - Separation of call control and connection control --
   derived from ITU-T ASON documents -- carriers think this
   is an important requirement.
 - Two new functions for the management function -- (1) control
   the control plane, and (2) More security requirements
 - Will produce version 03 of the docucment, which will
   then be ready for WG last call.

------

4. draft-ietf-ipo-ason-02.txt, presented by Osama
  - Relates IPO and CCAMP activities to ITU-T activities
  - Osama suggested work on the document is done,
     ready for WG last call
  - Chairs -- last call will be delayed until
    pertinent activities in the ITU-T are concluded.

5. draft-oki-ipo-optlink-req-00.txt, presented by Kohei Shlomoto
  - Requirements for optical link state information for traffic
    engineering
  - proposed requirements for optical link-state information for
    traffic engineering to solve the routing and wavelength
    assignment (RWA) problem in LNWC network.
  - different wavelength planes, where each plane corresponds to a
    network consisting of one wavelength
  - Need a label definition for wavelength definition: two aspects ( )
  - Need to indicate wavelength status
   - Signaling protocol aspects -- carry explicit wavelength info in
     signaling
