โœฆ Synopsis

The paper addresses the problem of designing efยฎcient scheduling policies for the transmission of control messages by hierarchical network protocols. Such protocols encounter a tradeoff between the desire to forward a control message across the tree as soon as it is received, and the desire to reduce control trafยฎc. Scheduling problems that arise in this context are deยฎned and discussed. The paper mainly concentrates on minimizing the average extra delay encountered by the control messages under an upper bound on the number of outgoing messages a node can send during a ยฎxed period of time. A polynomial-time algorithm is presented for the off-line version of the problem, and then several efยฎcient on-line heuristics are presented and compared.

## Chen and Chung proposed an improved scheme of hierarchical access control based on the Chinese Remainder theorem and symmetric encryption [1]. In this paper, we point out that the part of their scheme for adding a new class is not correct. Furthermore, we discuss how to fix this problem.
