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.
