Abstract

A quality of service parameter associated with message traffic transmitted from a smart items infrastructure through a middleware message routing engine to one or more enterprise applications is monitored. In response to the monitored quality of service parameter, a number of parallel message processors that route messages from the plurality of smart items to the message routing engine is controlled.
