Abstract:
The Application-Layer Traffic Optimization (ALTO) protocol [RFC7285]
has defined cost maps and endpoint cost maps to provide basic network
information. However, they provide only scalar (numerical or
ordinal) cost mode values, which are insufficient to satisfy the
demands of solving more complex network optimization problems. This
document introduces an extension to the base ALTO protocol, namely
the path-vector extension, which allows ALTO clients to query
information such as the capacity region for a given set of flows
(called co-flows). A non-normative example called co-flow scheduling
is presented to illustrate the limitations of existing ALTO endpoint
cost maps. After that, details of the extension are defined.
