Abstract: A method and apparatus for distributing load between a plurality of servers, for handling incoming service requests in a server system. When a service request in received in an access node, a primary server is assigned out of a set of primary servers, using a first scheduling algorithm, for performing a processing task for the received service request. The first scheduling algorithm is capable of selecting any primary server. Further, a secondary server is assigned out of a set of secondary servers, using a second scheduling algorithm, for performing a storing task for the received service request. The second scheduling algorithm is capable of selecting one specific secondary servers for a storing task.

Abstract: A method and apparatus for dynamically reconfiguring a server system. When a new server configuration is applied, a previous server configuration is saved. When receiving a service request, a first server is selected by using a first scheduling algorithm according to the new configuration. If the selected server is incorrect, a second server is selected by using a second scheduling algorithm according to the saved previous server configuration. User data associated with the received service request is moved from the second server, if correct, to the first server. In this way, stored data will be gradually and dynamically reorganized from the previous configuration to the new configuration in a relatively simple way.

Abstract: A method and apparatus for dynamically reconfiguring a server system (200). When a new server configuration is applied, a previous server configuration is saved. When receiving service requests, a first server is selected by using a first scheduling algorithm according to the new configuration. If the selected server was incorrect, a second server is selected by using a second scheduling algorithm according to the saved previous configuration. User data associated with the received service request is moved from the second server, if correct, to the first server. In this way, stored data will be gradually and dynamically re-organised from the old configuration to the new configuration in a relatively simple way.
