1. A method, comprising: informing, by a path computation device, a network management device of a plurality of possible probing profiles, wherein nodes of a computer network receive the plurality of possible probing profiles from the network management device; determining, by the path computation device, that particular information is desired from one or more particular nodes of the nodes of the computer network; selecting, by the path computation device, one or more particular probing profiles of the plurality of possible probing profiles based on the particular information, the one or more particular probing profiles specifying a type of probing that is required; instructing, by the path computation device, the one or more particular nodes to probe one or more particular destination nodes according to the one or more particular probing profiles; receiving probing reports from the one or more particular nodes; adjusting overbooking of one or more links within the computer network based on the probing reports; and relaxing path computation constraints at the path computation device based on the probing reports.
