In this paper, we propose several deadlock-free protocols for implementing the
generalized alternative construct, where a process
non-deterministically chooses between sending or receiving among various
synchronous channels. We consider general many-to-many channels and examine
in detail the special case of fan (many-to-one and one-to-many)
channels, which are common and can be implemented much more efficiently. We
propose a protocol that achieves an optimal number of message cycles per
user-level communication, significantly improving on previous results. We
propose several other “less aggressive” protocols, which may be
more suitable for some applications and networks, and demonstrate how to
adaptively switch between them and modify protocol parameters.
