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 delay to the Resource Consumer. However the base ALTO protocol
[ALTO] has documented only a single cost metric, i.e., the generic
"routingcost" metric (Sec. 14.2 of ALTO base specification [ALTO]).
In this document, we 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 tool. We currently document 11 new Performance Metric to
measure network delay, jitter, packet loss, hop count, and bandwidth.
The metrics documented in this document provide a relatively
comprehensive set of Cost Metrics for ALTO and allow applications to
determine "where" to connect based on end to end network performance
criteria. Additional Cost Metrics such as financial cost metrics may
be documented in other documents.
