Abstract
A first node operates in a network. The first node sends a polling message to a second node over a link at a first data rate, receiving an acknowledgement message from the second node. Based at least in part on receiving the acknowledgement message, the first node determines the second node is available to receive an information message. Based at least in part on the determining the second node is available to receive the information message, the first node sends the information message to the second node over the link at a second data rate. The second data rate is based at least on an indication of observed behavior of the link and the first data rate is based at least on the second data rate. For example, the first node may determine the first data rate to be a next slowest available data rate than the second data rate.
