Aguilera et al. introduced and solved the mailbox problem in [4], and used their mailbox algorithm to provide an efficient solution to the
N
-buffer problem. In the same paper, they also pointed out that both the mailbox problem and the
N
-buffer problem are solved by means of a more general problem: the signaling problem. The authors of [4] presented a non-blocking solution to the signaling problem, and asked whether a wait-free solution to the signaling problem exists. In our paper, we provide a positive answer to this question by introducing a bounded wait-free signaling algorithm and proving its correctness. In addition, our algorithm is more efficient than the one presented in [4] since it uses flags of smaller size. Furthermore, by using our algorithm, we provide a wait-free solution to the
N
-buffer problem which is more efficient than the one in [4].
