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.
