Abstract
A derived state value is calculated based on a plurality of component state values. As any of the plurality of component state values changes, the derived state value is recalculated. When sending information about a MAC address or other data between two components, the derived state value is included in the information sent. An object receiving a MAC address or other data from another object checks the validity of the received derived state value to determine whether to accept the new data and flush old data, to accept the new data, or to ignore the new data.
