RE: CCAMPs....some questions




*  
*  1	 During the Monday 11 December 2000 session which Fred chaired on
CCAMP, 
*  I asked the following question:
*  Since the Optical Transport Network (OTN) will have clients other than 
*  IP (eg SDH, ATM, FR) will IETF ensure that the GMPLS work takes the 
*  requirement to support multiple client layers into account?
*  
*  Fred answered that IETF was only responsible for IP protocols and an IP
*  client layer.  This is fair enough given IETF history and its modus
operandi
*  to date.  However, since many operators will require the support of
multiple
*  client layer technologies (as also borne out from OIF/ITU work on
requirements),
*  and thus requires that GMPLS must embrace an overlay model, the answer
Fred 
*  gave implies that IETF will not able to satisfy our requirements.  If
true, 
*  then we would not be in favour of the CCAMPs area (or more generally
IETF) 
*  developing OTN standards and the work should be left to standards bodies
who 
*  are prepared to address the needs of multiple client layer technologies,
eg ITU.
*  
  

My understanding is that the IETF is not developing OTN standards, but
protocols for the needs of IP, and nobody can blame them for that. GMPLS
should be well suited for those who want to add optical switches to their
existing router networks. 

Those of us who want to add dynamic control to our existing optical
transport networks, may find other solutions better. 

But we still keep a look at what comes out from IETF (and from the OIF),
because such implementations tend to be available in real products long
before the ITU standards.
