Re: [cso] Directional Changes for CSO work

[Young Lee <[e-mail]>]

Hi Daniel,

 

Thanks for your comment. 

 

The actual work on PCE will be worked on close collaboration between the PCE
WG and this “WG” (assuming this will be a new WG). This WG is focused on the
Query that tells “Network Stratum” (PCE is one of the component in the
network stratum), for instance, to estimate latency between point A and B,
then PCE might be used to estimate such request, or some other mechanism
similar to PCE. I believe this particular mechanism is already in place in
PCE. But how PCE communicates with the NCG needs to be collaborated between
PCE WG and this work. Another example is how PCE would provide virtual
network topology to application stratum is subject to the interest of the
PCE WG. 

 

In a nutshell, NS Query triggers many works in the network stratum in the
area of policy, network management, PCE, etc. 

 

I will look at “why needed” sections of both documents and clarify them. If
you can suggest some text on that, that will be also great. 

 

Best Regards,

Young

Hi Young,

 

the "why needed" sections of both documents are not very clear in my
opinion. Could you please better clafiry what is needed that is not actually
covered or that cannot be covered by the PCE wg?

 

>From my undestanding it seems that most of the extensions could be covered
by the PCE WG, but maybe i'm wrong.

 

Many thanks and best regards


Daniele

Subject: [cso] Directional Changes for CSO work

Hi, 

 

After a couple of conference calls with Ron Bonica (OPS AD) and Dan
Romanscanu (OPS AD), we narrowed down the scope of work and have broken the
CSO work into two pieces:

 

(i) Network Aware Application Mobility (NAAM)  

 

(ii) Network Stratum Query (NS Query)

 

Please see the draft charter descriptions in the attachment. 

 

Depending on the result of the IESG approval, we might pursue these two
pieces as separate work items down the road if both are approved. 

 

Please also note that among many potential CSO applicability, we have
narrowed the work in the context of Data Centers.  The following diagram
depicts the contexts of both NAAM and NS Query. 

 



 

If you are still interested in the new scope, we’d appreciate your comments
on the charter descriptions or any other related matters. 

Thanks. 

 

Best Regards,
Young
