Delivering Functions over Networks: Traffic and Performance Optimization
                     for Edge Computing using ALTO
           draft-yang-alto-deliver-functions-over-networks-01

Abstract

   As the rapid development of the Internet, huge amounts of data are
   being generated.  To satisfy user demands, service providers deploy
   services near the edge networks.  In order to achieve better
   performances, computing functions and user traffic need to be
   scheduled properly.  However, it is challenging to efficiently
   schedule resources among the distributed edge servers due to the lack
   of underlying information, e.g., network topology, traffic
   distribution, link delay/bandwidth, utilization/capability of
   computing servers.  In this document, we employ the ALTO protocol to
   help deliver functions and schedule traffic within the edge computing
   platform.  The protocol will provide information of multiple
   resources for the distributed edge computing platform.  The usage of
   ALTO will improve the efficiency of function delivery in edge
   computing.
