Hi all,
A new version of I-D, draft-randriamasy-alto-multi-cost-03.txt has been submitted, see below.
w.r.t the last version, this draft:
- introduces 2 use cases motivating and suggesting new Cost Types
- sketches the protocol updates that will be proposed in 4th version
after Quebec, with the example of the Endpoint Cost Service,
- is co-authored by Sabine Randriamasy and Nico Schwan.
The chosen example is the Endpoint Cost Service as :
- it is simple and contains the most visible impact of a Multi-Cost
transaction
- it reflects the initial motivation
- discussions on the ALTO mailing list are still ongoing on other
services such as Information resources Directory and the Cost Map Service.
As the goal of this draft is to initiate discussions, comments are
wellcome,
Best regards
Sabine

Filename: draft-randriamasy-alto-multi-cost
Revision: 03
Title: Multi-Cost ALTO
Creation date: 2011-07-11
WG ID: Individual Submission
Number of pages: 14
Abstract:
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.
