Hi Qin, Okay, thanks! This is interesting! It will be great to have an use case that describes how the GMPLS OAM can be supported/enhanced by TIME! Best regards, Georgios From: Qin Wu [mailto:bill.wu@huawei.com] Sent: woensdag 11 juni 2014 11:47 To: Karagiannis, G. (EWI); time@ietf.org Subject: RE: questions regarding considered data plane technologies Good question. The assumption we are making at this stage is the network we are tackling should have IP capability. To support multi-layer OAM, a good candidate data plane technologies we are thinking is BFD protocol since it can work independent of encapsulating protocols, and medium Types. Other existing data plane technologies can be reused, e.g., existing OAM protocols in layer 1&2&3. The TIME will most focus on how to abstract OAM information common to various Layer(especially layer 4 to 7) and provide them to management entity via unified interface. It doesn’t matter what kind of data plane technologies are used. To apply multi-layer OAM to service function chaining environment, new data plane OAM atop layer 3 may be specified. That could be a new shim layer that carries OAM information to support various OAM functions. The TIME also need to think about how to abstract these kind of OAM information from that layer in the form of Generic Yang Data Model.

Are the same ones that are being considered for GMPLS, e.g., packet, cell, TDM, wavelength, etc? Best regards, Georgios
