Abstract: A system and method facilitate modifying behavior of an application coupled to a device and a server based on bandwidth. The method determines a first bandwidth state. A change is then detected from the first bandwidth state to a second bandwidth state. Subsequently, the behavior of an application is changed based on bandwidth parameters of the second bandwidth state.
