Summary:
|
Recommendation ITU-T G.8121/Y.1381 specifies both the functional components and the methodology that should be used in order to specify multi-protocol label switching – transport profile (MPLS-TP) layer network functionality of network elements; it does not specify individual MPLS-TP network equipment as such.
Amendment 1:
– Provides new Annex A "Mapping MPLS-TP packets to OTN using IMP".
– Replaces Maintenance Communication Channel (MCC) by Management Communication Channel (MCC).
– Makes editorial corrections in Figure 11-37 to Figure 11-40 (replacing ETH_FP by ETH_AP) and Table 11-17.
– Updates the publication dates in References.
Corrigendum 1:
– Adds "(Pattern)" to MTDe_TT_Sk_MI_1TH_Start in Table 9-19.
– Changes MI_PCS[1…M] to MI_CoS[1...M] in Figure 11-2.
Amendment 2:
– Specifies management information signals for reporting the state of linear and ring protection processes to equipment management functionality in clause 9.1.
– Adds missing abbreviation for MTp and updates some references.
