Abstract: Method, system, and programs for estimating customer satisfaction associated with a customer are disclosed. In one example, a plurality of time series is obtained. Each time series comprises observations for one of a plurality of events associated with the customer. Each observation for each of the events is made with respect to a time period. A plurality of individual measures is estimated. Each of the individual measures is associated with one of the plurality of events. Each individual measure is estimated based on a time series including a plurality of observations associated with the event. Information is received indicative of a number of events selected from the plurality of events. An aggregated measure is computed indicative of a degree of satisfaction of the customer based on individual measures associated with the number of events.

Abstract: A technique for address registration and resolution is disclosed. In one embodiment, the technique is realized by an address registration and resolution service that is applicable to in-band in-fiber, out-of-band in-fiber and out-of-band out-of-fiber O-UNI signaling configurations. Through this address registration and resolution scheme, an optical service subscriber or optical access service provider can register various client-layer addresses (i.e., establish an association between the client addresses and the optical network points of attachment for the network intelligence.) An intelligent optical routing protocol will propagate this information all over the network and use this information to locate a corresponding optical client device and the optical network point of attachment. The optical network signaling can then perform the network internal signaling for on-demand optical service provisioning.
