In terms of QoS I don't think there is a statement yet from OGSA -
though we will hopefully be holding an ad-hoc BoF at OGF19 to discuss
this issue.

Dave,

A very good question. We are working on just this problem at uva - but
think a broader discussion is in order.

Dear OGSA WG,

 

I have an action from the OGSA Dqta WG to ask you about service
creation.  When creating services in OGSA, how does the client specify
the following properties:


- Lifetime of Service
- (Storage) Size
- Default QoS requirements 
- Default (security) policies
- Service Location (on which Server say) 
- Provisioning

 

Do you have a common pattern for service creation, or common definitions
of the above items?

 

Currently we are assuming the existence of factory services that can
create shorter-term services.  E.g. in data transport, the long-lived
service will create a short-lived service that manages the actual data
transfer.  Clients will send control messages to the shorter-lived
service.

 

This seems similar to the pattern originally encoded in OGSI.  Is it
still the OGSA-approved way to manage service creation?

 

Best wishes,
