摘要：
A method for altering fixed priority conflicts in accessing crossbar switches interconnecting processor-to-processor communications. A fixed priority conflict resolution is substituted for random conflict resolution. There is utilized a method of random restraint for the purpose of restoring the symmetry of access. This is performed by way of a random experiment at each processor using a local threshold parameter and permitting access only when the experimental value exceeds the threshold.
