Abstract
According to some implementations of the present invention, RFID devices and middleware servers are automatically provisioned with a network address and with instructions for sending a request for a middleware server to a middleware server assigner. In some implementations, the middleware server assigner is a load balancer. In some implementations, a middleware server is associated with a plurality of RFID devices by associating a middleware server network address or names with the network addresses of the RFID devices. Preferred methods also provide for redundancy of middleware servers and dynamic re-assignment of RFID devices from an unavailable middleware server to an available middleware server.
