This really hasn't been discussed within the WG yet. However, as you
point out, it could be done via extensibility elements - where allowed
in WSDL 1.1 and pretty much everywhere in WSDL 1.2. I suspect that
WS-Policy etc would be another interesting alternative.

Thanks for your response Jeff.

 

If I understand WSDL properly, one could allow for QoS to be represented
in a WSDL file by using extensibility options.

While it may not have been formally discussed on w3c.org, is this
currently the preferred way for applying QoS descriptions to WSDL files?
(I assume there must be some discussion on this...)

 

Or am I just totally confused?  :)

 

Thanks,

 

Ryan

Subject: RE: Quality of Service

 

Ryan, the following requirement has been accepted by the W3C Web
Services Description Working Group (WG), but the WG hasn't as yet
discussed any proposals for meeting that requirement.

 

R117 

The description language SHOULD allow specifying QoS-like policies and
mechanisms of a Web Service. For instance, an indication of how long it
is going to take a Web Service to process the request. (From WG
discussion. Last discussed 12 April 2002.)

Hi,

 

Long time listener...but I don't post much.  I've got a question about
QoS in WSDL 1.2.

I've gone over the 1.2 specs and there doesn't seem to be any
fucntionality offered by WSDL directly for describing the QoS for a web
service.  Is there a practice for defining QoS within 1.2?  Does one
have to use the extensibility options?

 

Thanks,

 

Ryan
