Re: [cso] Mailing List Sunset

Hi Lars, I missed the Taipei meeting so wasn't sure of the reasoning 
behind the decision not to charter a CSO research group. I did notice at 
previous side meetings it was difficult to get in a word edge wise over 
the cacophony of voices at the side meetings. However, I have been 
involved in writing several of the CSO related documents, e.g., 
http://tools.ietf.org/html/draft-bernstein-alto-large-bandwidth-cases-00, so 
maybe we can discuss the chartering of CSO on this list.

The general CSO research topic is to figure out ways that the two 
strata, application and network, can work better together. A specific 
sub-problem of this is being addressed by the IETF ALTO working group. 
When we presented the above draft to the ALTO WG in Quebec there seemed 
a fairly clear understanding of the research problems we were interested 
in and how they went beyond ALTO charter and scope.

I see a number of research drivers for this work: (a) Cross Stratum 
Resource Optimization -- problem statement and algorithms, (b) Trends in 
data center traffic (inter, intra, dynamics, etc...), (c) Joint 
resilience/recovery.  Work in these areas would influence the 
development of "interfaces" between the strata which is the overarching 
goal of the effort.

Why the IRTF/IETF? In the areas of GMPLS and PCE we have well 
established tools for network optimization and resilience. Note that the 
first GMPLS deployments in the early 2000s we driven by optimization 
(via soft permanent connections) and new mesh recovery options. Other 
groups such the Open Grid Forum took a more application layer focus or 
did not take into account the network tools in place (GMPLS, PCE) or the 
arms length relationship between many data centers and carriers.

I have recently put together a longer breakdown of CSO related research 
topics and how they fit together and could post it, if it would be 
helpful in chartering a CSO IRTF group. I frequently serve as a reviewer 
for IEEE, ACM, and OSA publications, have served on NSF proposal review 
boards, and have consulted to DARPA in the establishment of research 
programs. This seems to me to be a fairly rich research area and one 
that can mutually benefit the IRTF by association.

Greg B.
