Status reporting with ancillary data

摘要

Resources shared by plural users supply a busy signal to a requesting user whenever any one of the users has a right of access to the resources. Ancillary data accompanies the busy signal identifying the user having the right of access. The requesting user may use the ancillary data to adjust its right of access by communication with the one user. The right of access may include a queue of access requests, each request having the ancillary data.
