Introduction 82 This extension is based on "draft-galikunze-ccamp-opt-imp-snmp- 83 mib-00" and "draft-kunze-g-698-2-management-control-framework-02", 84 for the relevant optical parameters mainly (but not restrictriced to) 85 described in recommendations like ITU-T G.698.2 [ITU.G698.2] and 86 G.694.1 [ITU.G694.1]. This document further extend the draft- 87 dharinigert-ccamp-g-698-2-lmp-03. The LMP Model from RFC4902 is 88 extended to provide link property correlation between a client and an 89 OLS device. By using LMP, the capabilities of either end of this 90 link are exchanged where the term 'link' refers to the attachment 91 link between OXC and OLS (see Figure 1). By performing link property 92 correlation, both ends of the link can agree on a common parameter 93 window that can be supported and supervised by each device. The 94 actual selection of a specific parameter value whithin the parameter 95 window is outside the scope of LMP. In GMPLS the parameter selection 96 (e.g. wavelength) is performed by RSVP-TE and Wavelength routing by 97 IGP. This document does not include the ITU-T G.698.2 "application- 98 code" and few other parameters described in the draft draft- 99 dharinigert-ccamp-g-698-2-lmp-03 101 Figure 1 Extended LMP Model ( from [RFC4209] ) 103 +------+ Ss +------+ +------+ Rs +------+ 104 | | ----- | | | | ----- | | 105 | OXC1 | ----- | OLS1 | ===== | OLS2 | ----- | OXC2 | 106 | | ----- | | | | ----- | | 107 +------+ +------+ +------+ +------+ 108 ^ ^ ^ ^ ^ ^ 109 | | | | | | 110 | +-----LMP-----+ +-----LMP-----+ | 111 | | 112 +----------------------LMP-----------------------+ 114 OXC : is an entity that contains transponders 115 OLS : generic optical system, it can be - 116 Optical mux, Optical demux, Optical Add 117 Drop Mux, etc 118 OLS to OLS : represents the black-Link itself 119 Rs/Ss : inbetween the OXC and the OLS 121 Figure 1: Extended LMP Model 123 2. Extensions to LMP-WDM Protocol 125 This document defines extensions to [RFC4209] to allow the Black Link 126 (BL) parameters of G.698.2, as described in the draft draft- 127 kunze-g-698-2-management-control-framework-02, to be exchanged 128 between a router or optical switch and the optical line system to 129 which it is attached. In particular, this document defines 130 additional Data Link sub-objects to be carried in the LinkSummary 131 message defined in [RFC4204] and [RFC6205]. The OXC and OLS systems 132 may be managed by different Network management systems and hence may 133 not know the capability and status of their peer. The intent of this 134 draft is to enable the OXC and OLS systems to exchange this 135 information. These messages and their usage are defined in 136 subsequent sections of this document. 138 The following new messages are defined for the WDM extension for 139 ITU-T G.698.2 [ITU.G698.2]/ITU-T G.698.1 [ITU.G698.1]/ 140 ITU-T G.959.1 [ITU.G959.1] 141 - BL_General (sub-object Type = TBA) 142 - BL_Ss (sub-object Type = TBA) 143 - BL_SsRs (sub-object Type = TBA) 144 - BL_Rs (sub-object Type = TBA) 145 - BL_OLS_Status (sub-object Type = TBA) 147 3.

Security Considerations 403 LMP message security uses IPsec, as described in [RFC4204]. This 404 document only defines new LMP objects that are carried in existing 405 LMP messages, similar to the LMP objects in [RFC:4209]. This 406 document does not introduce new security considerations. 408 10. IANA Considerations 410 LMP [RFC4204] defines the following name spaces and the ways in which 411 IANA can make assignments to these namespaces: - LMP Message Type - 412 LMP Object Class - LMP Object Class type (C-Type) unique within the 413 Object Class - LMP Sub-object Class type (Type) unique within the 414 Object Class This memo introduces the following new assignments: LMP 415 Sub-Object Class names: under DATA_LINK Class name (as defined in 416 [RFC4204]) - BL_General (sub-object Type = TBA) - BL_Applicationcode 417 (sub-object Type = TBA) - BL_Ss (sub-object Type = TBA) - BL_SsRs 418 (sub-object Type = TBA) - BL_Rs (sub-object Type = TBA) - OLS_Status 419 (sub-object Type = TBA) 421 11.
