Overview

Application-Layer Traffic Optimization (ALTO) is an IETF protocol to provide network information to applications. The ALTO project in OpenDayLight is an effort to implement ALTO in OpenDayLight. In addition to implementing the ALTO base protocol, the project leverages OpenDayLight to introduce a provisioning interface for ALTO.

In particular, ALTO defines abstractions and services to provide simplified network views and network services to guide application usage of network resources. And it includes five services:

  • Network Map Service: The Map Service provides batch information to ALTO clients in the forms of ALTO network maps.
  • Cost Map Service: An ALTO cost map provides costs between defined groupings.
  • Filtered Map Service: The Filtered Map Service allows ALTO clients to query an ALTO server on ALTO network maps and/or cost maps based on additional parameters.
  • Endpoint Property Service: This service allows ALTO clients to look up properties for individual endpoints.
  • Endpoint Cost Service: The Endpoint Cost Service allows an ALTO server to return costs directly amongst endpoints.

If you want to know more about ALTO, please read Application-Layer Traffic Optimization (ALTO) Protocol (RFC 7285).
