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 it
proposes to include information on multiple cost types in a single
ALTO transaction, providing a better mapping of the Selected
Endpoints to needs of the growing diversity of Content Networking
Applications and to the network conditions. Secondly it proposes new
cost types, that are an abstraction of time-sensitive network
information as viewed by the Network Provider. All this also helps
producing a more robust choice when multiple Endpoints must be
selected.
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. The second part proposes use cases
motivating further definitions of additional CostTypes and Cost
related attributes and capabilities.
