摘要： Technologies relating to work load distribution. A request is received for access to one of n server processes, where n is an integer greater than one. A mixing function is applied to an identifier associated with the request to generate a reproducible output representative of the identifier. A modulo operation is applied to the output, where a dividend in the modulo operation is the output and a divisor in the modulo operation is n, to determine a remainder. The request is assigned to a server process from the n server processes in accordance with the remainder.
