Hello,
A new version draft-ietf-alto-multi-cost-03 has been submitted.
This version addresses WG comments from Hans, Xin and Richard.
We still need to finalize the consistency check for E/endpoints, C/client and
S/server.
Can the comment authors please take a look and check whether their other
comments were correctly addressed?
Thanks again for your feedback,
Sabine
The updates summary is as follows
----------------------------------------------------------------------
*** Abstract
Rephrased according to comments.
*** Section "1. Introduction"
Rephrased paragraphs 2,3,4 according to comments
*** Section "2. Terminology"
Added terms "Client" and "Server" to solve ambiguities on client and Client"
Whole text: updated according to these rules.
*** Section "4.1.2. Accept Input Parameters"
- transferred the text introducing extended predicates from the "or-constraint"
to the "constraints" paragraph.
- stressed that "If this resource's "max-cost-types" capability has a value
greater than 0, then this parameter is an array of extended constraint
predicates as defined below and related to each other by a logical AND".
- in or-constraints:
(i) added "This parameter MUST NOT contain any empty array of AND predicates"
and (ii) added an example interpretation of an or-constraint
*** Section "4.1.2. Accept Input Parameters"
*** Section "4.2.2. Accept Input Parameters"
updated the or-constraint member to: JSONString or-constraints<1..*><1..*> +
added sentence explaining why
****** Updates on ALTO response meta
Section: 3.1,
Section: 5.2 .. example 1,
Section: 5.3 .. example 2,
Section: 5.5 .. example 4
added "cost-type : {}" in the meta
Section: 4.1.3 Response
Section: 4.2.3 Response
updated description of the meta response accordingly

>>Abstract:
>> The ALTO (Application Layer-Traffic Optimization) Protocol
>> ([RFC7285]) defines several services that return various metrics
>> describing the costs between network endpoints. An ALTO Server may
>> offer a variety of cost metrics, based on latency,bandwidth, hop
>> count, jitter, or whatever else the ALTO Server deems useful. For
>> example, when downloading a file that is mirrored on several sites,
>>a
>> user application may consider more than one metric, perhaps trading
>> bandwidth for latency to determine the most efficient mirror site.
>>
>> While the base ALTO Protocol allows a client to use more than one
>> cost metric, to do so, the client must request each metric
>> separately. This document defines a new service that allows a
>>client
>> to retrieve several cost metrics with one request, which is
>> considerably more efficient. In addition, this document extends the
>> ALTO constraint tests to allow a user to specify an arbitrary
>>logical
>> combination of tests on several cost metrics.
