Abstract

A server of a client/server network uses server processes to access shared server resources in response to service requests from client computers connected to the network. The server uses a measured workload indication to assign a received client service request to a server process. In one embodiment the measured workload indication is determined in response to an input from the server's administrator specifying the number of clients (N) which may request service from the server. Using the number N, the server accesses a predefined table to determine the number of clients that may be assigned to each process. In another embodiment, a busy indicator provides a measured workload indication for each active process. The server uses the busy indicator to assign a new client service request to the least busy process.
