Abstract

An adaptive feedback technique is described for a Mobile IP environment in which Mobile IP mechanisms provide early feedback to mechanisms in the transport layer and/or application layer of a mobile node in response to detection of changes in link characteristics of the communication used by the mobile node to communicate with a data network. Using the early feedback information, appropriate measures may then be taken in order to accommodate the changes in link characteristics. Such appropriate measures may include, for example, providing feedback to media aware applications in order to allow such applications to dynamically adjust their bandwidth requirements to accommodate the new link characteristics, modifying timeout parameters, modifying an encoding formats to accommodate the new link characteristics, notifying participants in a real-time application session of the detected changes in the link characteristics, etc.
