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.

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

   This document, proposes a set of Cost Metrics, derived and aggregated
   from routing protocols with different granularity and scope, such as
   BGP-LS,OSPF-TE and ISIS-TE, or from end-to-end traffic management
   tools.  It currently documents Network Performance Cost Metrics
   reporting on network delay, jitter, packet loss, hop count, and
   bandwidth.  These metrics may be exposed by an ALTO Server to allow
   applications to determine "where" to connect based on network
   performance criteria.  Additional Cost Metrics involving ISP specific
   considerations or other network technologies may be documented in
   further versions of this draft.
