[armd] datacenter reference architecture draft

[Manish Karir <[e-mail]>]

The following draft was submitted to hopefully help focus the ARMD discussion around a common architecture.

Comments and feedback are welcome.  The goal of the writeup really is to abstract away specific datacenter designs
each of which focuses on solving a particular application/traffic pattern by trying to talk about what is common between 
the various designs.  Hopefully this will help some of the very varied discussion that has taken place in this WG so far.

Thanks.

Title:		 Data Center Reference Architectures

WG ID:		 Individual Submission
Number of pages: 11

Abstract:
  The continued growth of large-scale data centers has resulted in a
  wide range of architectures and designs.  Each design is tuned to
  address the challenges and requirements of the specific applications
  and workload that the data is being built for.  Each design evolves
  as engineering solutions are developed to workaround limitations of
  existing protocols, hardware, as well as software implementations.

  The goal of this document is to characterize this problem space in
  detail in order to better understand if there is any gap in making
  address resolution scale in various network designs for data
  centers.  In particular it is our goal to peel back the various
  optimization and engineering solutions to develop generalized
  reference architectures for a data center.  We also discuss the
  various factors that influence design choices in developing various
  data center designs.
