[01:34:02] yes - it gives all sorts of problems for the h/w implementaors (across the industry) and it's better for an ach application to put it's own TLVs if needed after the fixed part of the protocol [01:34:30] agree with you [01:34:35] I think that we ned to update the ACH text to remove the ACH feature [01:34:53] I mean removethe ach lv feature [01:35:22] yeah, thanks for clarify [01:35:48] Thank you [01:36:35] On Option 4, how do you interoperate?

[01:49:15] Luca: Option 2 is not really needed any longer [01:50:13] Might be easier to update the existing RFC rather than progressing a new draft [01:50:53] YJS: If you are using control word, make control word mandatory, if not use TTL [01:50:54] rahul aggwal speking [01:51:03] speaking [01:51:50] Italo Busi [01:53:35] Can't guarentee that TTL will deliver OAM frames properly. Luca, thinks Italo was specifically talking about how to ensure that a TTL expires in the middle in the flow [01:54:36] A decision to make this a working group draft will have to be taken to the list. The chairs will send a message to list to poll for working group adoption [01:55:20] The TTL discussed here is the PW label not the MPLS label [01:56:07] Luca wants a ruling on what track the document will take.
