Abstract
Service requests, which are used to properly process a network access request received from a client, are processed by routing the service requests between at least two service component instances according to a load balancing algorithm. Load balancing includes: calculating a first ticket amount and a second ticket amount; assigning the first ticket amount to a first instance and the second ticket amount to a second instance; using a selection scheme to select an instance having a ticket amount greater than a threshold amount to process a service request; decrementing the ticket amount corresponding to the instance selected; and scheduling the instance selected to receive a service request. The present invention may further include distinguishing between operable and inoperable instances, providing ticket amounts that are not based on performance ratings to inoperable instances, and providing ticket amounts that are based on performance ratings to operable instances.
