ØWe propose a measurement-based AC algorithm that constantly gathers data on the ongoing users QoS in the network by exploiting the network’s Self Awareness. This data is available in one or more locations in the network where the decision is taken. ØThis does not require any special mechanism since the CPN already collects QoS information on all links and paths that the SPs have explored and on all paths that any user is using in the network. ØIt is a multiple criterion AC algorithm in which the QoS criteria are specified by the user.
