Lou,

I must have been asleep but I don’t remember hearing of an issue.  It was my understanding that AMP and GMP both use G.709 encoding in the data plane, so why would we want to make what appears to be an artificial distinction?

Irrespectively Yours,

John

John,

Do you have an alternate proposal on how to address the issue, or do you just see an issue?

(If the former, the onus will fall on you to provide one. If the latter, it'll fall to Sergio And Danielle to recap the presented issue.)

Lou

Oggetto: [CCAMP] G.709 signaling - encoding Type

Daniele,

The presentation slide#3 says:  “encoding type indicates AMP or GMP”.   I don’t think this is the case.  We use  G.709 ODUk as encoding type.  There is no explicit indication of AMP or GMP there.  Are you proposing to change this?

Note that AMP/GMP can be inferred from Signal Type in traffic param & Length field ( = 8) in the label.

Thanks
Rajan
