Abstract:
The Application-Layer Traffic Optimization (ALTO) Service has defined
both the endpoint cost service (ECS) and cost maps to provide
information to applications about network path properties (e.g.,
routingcost) from a set of source network points to a set of
destination network points, where each network point can be a single
endpoint (in ECS) or a PID which represents a set of endpoints (in a
cost map). Considering, conceptually, both ECS and cost map as
returning a matrix, indexed by sources and destinations as row and
column, the current ALTO protocol [RFC7285] allows the elements in
the matrix to be only scalar (i.e., numerical or ordinal). This,
however, is limiting in many use cases. This document discuss
multiple use cases where scalar-elements can be limitations. It then
defines new cost types to allow general cost types, such as vectors
to represent use cases such path vectors.
