Summary:
This draft introduces the concept of a closed-loop link provisioning 
process for dynamic IP link configuration in an automatically switched 
transport network. We identify major phases, which completes an 
automatic link-provisioning cycle. First in the traffic engineering 
phase, both network internal information and external information can 
be applied to proactively or reactively triggering circuit switched 
links. Secondly in the network design phase, we distinguish different 
types of link design. Finally in the choice phase, we outline a set of 
criteria for choosing a final link amongst a set of candidate links. 
The criteria are based on maximizing the value of the user network, 
where value is computed from: bandwidth, distance, and duration. We 
propose these criteria be utilized in studies of dynamic link 
provisioning.
