    ALTO Extensions for Collecting Data Center Resource Information
                   draft-lee-alto-ext-dc-resource-03

Abstract

   In a networked application environment where resources (e.g.,
   computing, storage, etc.) are geographically distributed in Data
   Centers, a key decision is to allocate the application request to an
   "optimal" Data Center location in which to host the application
   request.  Key constraints in this decision include resource
   availability, network cost, infrastructure constraints (e.g., power)
   and others.  This draft proposes an ALTO extension to support data
   center resource information model and its related protocol
   extensions.

1.  Introduction

   In a networked application environment where resources (e.g.,
   computing, storage, etc.) are geographically distributed in Data
   Centers, a key decision is to allocate the application request to an
   "optimal" Data Center location in which to host the application
   request.  Key constraints in this decision include resource
   availability (e.g., memory, storage, CPU, etc.), DC network cost, DC
   network resource constraints (e.g., bandwidth), structure constraints
   (e.g., Data Center power consumption) and others.

   This draft describes data center resource information model in the
   context of i2aex (infrastructure to application exchange) and
   proposes its related ALTO protocol extensions.
