Internet-Draft   draft-dharinigert-ccamp-g-698-2-lmp-02    February 2013


1.  Introduction

   This extension is based on
   "draft-galikunze-ccamp-g-698-2-snmp-mib-02" and
   "draft-kunze-g-698-2-management-control-framework-02", for the
   relevant optical parameters mainly (but not restrictriced to)
   described in recommendations like ITU-T G.698.2 [ITU.G698.2].  The
   LMP Model from RFC4902 is extended to provide link property
   correlation between a client and an OLS device.  By using LMP, the
   capabilities of either end of this link are exchanged where the term
   'link' refers to the attachment link between OXC and OLS (see Figure
   1).  By performing link property correlation, both ends of the link
   can agree on a common parameter window that can be supported and
   supervised by each device.  The actual selection of a specific
   parameter value whithin the parameter window is outside the scope of
   LMP.  In GMPLS the parameter selection (e.g. wavelength) is performed
   by RSVP-TE and Wavelength routing by IGP.

2.  Extensions to LMP-WDM Protocol

   This document defines extensions to [RFC4209] to allow the Black Link
   (BL) parameters of G.698.2, as described in the draft



Hiremagalur, et al.      Expires August 25, 2013                [Page 3]


Internet-Draft   draft-dharinigert-ccamp-g-698-2-lmp-02    February 2013


   draft-kunze-g-698-2-management-control-framework-02, to be exchanged
   between a router or optical switch and the optical line system to
   which it is attached.  In particular, this document defines
   additional Data Link sub-objects to be carried in the LinkSummary
   message defined in [RFC4204] and [RFC6205].  The OXC and OLS systems
   may be managed by different Network management systems and hence may
   not know the capability and status of their peer.  The intent of this
   draft is to enable the OXC and OLS systems to exchange this
   information.  These messages and their usage are defined in
   subsequent sections of this document.

       The following new messages are defined for the WDM extension for
           ITU-T G.698.2 [ITU.G698.2]/ITU-T G.698.1 [ITU.G698.1]/
           ITU-T G.959.1 [ITU.G959.1]

            - BL_ApplicationCode  (sub-object Type = TBA)
            - BL_Ss               (sub-object Type = TBA)
            - BL_SsRs             (sub-object Type = TBA)
            - BL_Rs               (sub-object Type = TBA)
            - BL_OLS_Status       (sub-object Type = TBA)


3.  Black Link General Parameters - BL_General

   These are the general parameters as described in [G698.2] and
   [G.694.1].  Please refer to the
   "draft-galikunze-ccamp-g-698-2-snmp-mib-02" for more details about
   these parameters and the [RFC6205] for the wavelength definition.

        The general parameters are
            1. Bit-Rate/line coding of optical tributary signals
            2. Wavelength - (Tera Hertz) 4 bytes (see RFC6205 sec.3.2

      is used in the message, then the vendor transaction class need not
      be used (i.e. all 0) and the optional parameters except nominal
      central frequency need not be used. When vendor transaction class
      is used in the message, then the Single-channel application code
      need not be used (i.e. all 0) and the optional parameters needs
      to be used.

   This message is sent by the OLS to the OXC.  It includes the
   wavlength information and the status of the OLS.

    1. Wavelength - The wavelength which has been accepted by the OLS
       (Tera Hertz) 4 bytes. (see RFC6205
            sec.3.2 and 3.3 TLV): Grid / Cannel Spacing / Identifier / n
    2. Length of the  Wavelength Availability Map  1 byte
    3. Wavelenth Availability bits - variable bits depending on the
       nunmer of wavelengths available (For eg 96 bits for C-band 50GHz)
       (Allocation is in multiples of 1byte - 96 bits - 12 bytes)
       0 - wavelength is available, 1 - used    - variable length
    4. Current Input Power (0.1dbm) 4 bytes
       - This is the current input power at OLS
    5. Delta between output power at the Src(OXC)and Input Power
       at OLS (0.1dbm) 4 bytes
       - This is the delta between the input power and the transmitted
       output power at the OXC (from message 2.2 BL_Src)
    6. Threshold of the input power at OLS 4 bytes
       - This is the power level above which the OLS will not function.
    7. Current Output Power (0.1dbm) 4 bytes
       - This is the transmitted output power at the OLS.
    8. Status of Rx link at OLS 2 bytes

    9. Status of Tx link at OLS 2 bytes

9.  Security Considerations

   LMP message security uses IPsec, as described in [RFC4204].  This
   document only defines new LMP objects that are carried in existing
   LMP messages, similar to the LMP objects in [RFC:4209].  This
   document does not introduce new security considerations.


10.  IANA Considerations

   LMP [RFC4204] defines the following name spaces and the ways in which
   IANA can make assignments to these namespaces: - LMP Message Type -
   LMP Object Class - LMP Object Class type (C-Type) unique within the
   Object Class - LMP Sub-object Class type (Type) unique within the
   Object Class This memo introduces the following new assignments: LMP
   Sub-Object Class names: under DATA_LINK Class name (as defined in
   [RFC4204]) - BL_General (sub-object Type = TBA) - BL_Applicationcode
   (sub-object Type = TBA) - BL_Ss (sub-object Type = TBA) - BL_SsRs
   (sub-object Type = TBA) - BL_Rs (sub-object Type = TBA) - OLS_Status
