Hi Xian, Thanks for your reply. Do we still need to keep “Flag F”? Flag F: indicates whether LO ODU2e is supported. Thanks, Ladan From: Zhangxian (Xian) [mailto:zhang.xian@huawei.com] Sent: Sunday, September 08, 2013 8:44 PM To: Pickering, Ladan Cc: ccamp@ietf.org Subject: RE: gmpls-g.709-lmp-discovery Rev02 vs Rev06 - OTU2e Hi, Ladan, The change made in the OTN LMP draft was just reflecting what was agreed a while ago in CCAMP WG that only G.709 is referenced. As you probably already know that OTU2e is not supported in G.709( as the note states below Table 7-1 of the version published in Feb. 2012), but rather specified in G.sup43. That’s why we do not cover it any more in the our OTN LMP draft. I hope this clarify your question. Regards, Xian From: ccamp-bounces@ietf.org [mailto:ccamp-bounces@ietf.org] On Behalf Of Pickering, Ladan Sent: 2013年9月7日 7:46 To: ccamp@ietf.org Subject: [CCAMP] gmpls-g.709-lmp-discovery Rev02 vs Rev06 - OTU2e Hi Xian, I have noticed that in revision 02 of the LMP draft, OTU2e was defined as a HO-ODU with a value of 5 under OD(T)UK, but on rev 06 of this draft this has been removed, but “Flag F” corresponding to ODU2e as a LO-ODU is still in rev 6. Version 2: OD(T)Uk field Signal type of HO ODUk or OTUk ------------- ------------------------------ 0 Reserved (for future use) 1 HO ODU1 or OTU1 2 HO ODU2 or OTU2 3 HO ODU3 or OTU3 4 HO ODU4 or OTU4 5 OTU2e 6 OTU3e1 7 OTU3e2 8-15 Reserved (for future use) Version 6: OD(T)Uk field Signal type of HO ODUk or OTUk ------------- ------------------------------ 0 Reserved (for future use) 1 HO ODU1 or OTU1 2 HO ODU2 or OTU2 3 HO ODU3 or OTU3 4 HO ODU4 or OTU4 5-15 Reserved (for future use) Can you please help me understand why OTU2e was removed from OD(T)UK? If we have a link that supports OTU2e and allows a 11.095 rate, what should go in ODU(T)UK? Thanks, Ladan
