Supporting multi-domain Use cases with ALTO.

Many multi-domain use cases can benefit substantially from network information exposure, but also introduce new, key requirements that existing exposure solutions, such as the Application-Layer Traffic Optimization (ALTO) protocol, do not satisfy. In this talk, we review several important multi-domain use cases, discuss the key network information exposure requirements to support these use cases, and present a unified exposure architecture as well as novel mechanisms and abstractions to substantially improve the ALTO framework in the multi-domain setting.
