                 ALTO Traffic Engineering Cost Metrics
                      draft-wu-alto-te-metrics-00

Abstract

   Cost Metric is a basic concept in Application-Layer Traffic
   Optimization (ALTO).  It is used in both the Cost Map Service and the
   Endpoint Cost Service.  Future extensions to ALTO may also use Cost
   Metric.

   Different applications may benefit from different Cost Metrics.  For
   example, a Resource Consumer may prefer Resource Providers that have
   low latency to the Resource Consumer.  However the base ALTO protocol
   [ALTO] has defined only a single cost metric, i.e., the generic
   "routingcost" metric (Sec. 14.2 of ALTO base specification [ALTO]).

   In this document, we define XXX Cost Metrics, derived from OSPF-TE
   and ISIS-TE, to measure network delay, jitter, packet loss, hop
   count, and bandwidth.  The metrics defined in this document provide a
   relatively comprehensive set of Cost Metrics for ALTO focusing on
   traffic engineering.  Additional Cost Metrics such as financial cost
   metrics may be defined in other documents.
