IETF is designing a new service called ALTO (Application Layer
traffic Optimization) that includes a "Network Map Service", an
"Endpoint Cost Service" and an "Endpoint (EP) Ranking Service" and
thus incentives for application clients to connect to ISP preferred
Endpoints. These services provide a view of the Network Provider
(NP) topology to overlay clients.
The present draft proposes a light way to extend the information
provided by the current ALTO protocol. The purpose is to broaden the
possibilities of the Application Clients in two ways: firstly by
providing a better mapping of the Selected Endpoints to needs of the
growing diversity of Content Networking Applications and to the
network conditions, secondly by producing a more robust choice of
multiple Endpoints, helping thus out for efficient Multi-Path
transfer.
There are 2 parts in this draft: the first part initiates protocol
extensions to support requests on multiple Cost Types in one single
transaction. These first extensions also integrate the discussions
within the ALTO Working Group and focus on the Endpoint Cost Service.
The second part proposes two use cases motivating further definitions
of additional CostTypes and Cost Attributes related to timeframe and
validity period.
