A scheduler for controlling when entities are operated upon by the server. The scheduler includes N entities, where N is an integer greater than or equal to 2. Each entity has a rate at which it is to receive service from the server. The scheduler includes a memory having finishing times f.sub.i of the N entities, where f.sub.i corresponds to the time the i'th entity is to be operated upon by the server. The scheduler includes a virtual clock that keeps track of virtual time so the finishing times f.sub.i can be identified. The scheduler includes a controller which chooses entities to be operated upon by the server as a function of the finishing times. The controller slows virtual time to provide service to the entities. The controller is connected to the virtual clock and the memory. A scheduler for controlling when entities are operated upon the server. The scheduler includes N entities, where N is an integer greater than or equal to 2. Each entity has a rate at which it is to receive service from the server. At least a first entity of the N entities has a plurality of connections, and the controller chooses the first entity to provide service when at least one of the plurality of connections is waiting for service and has a finishing time which is the earliest finishing time of the entities waiting for service.
