<p>In a telecommunication controller (1), a messaging system allows real time communication between sub-systems such as a main controller (2) and line cards (3). Requesting applications (5) create a proxy (12) which controls the function call via a middleware engine (11) in each of the sub-systems (2, 3). A resource middleware engine (11) calls a server (13) which in turn controls performance of the function on the resource (10). The proxies (12) are transient. The servers (13) are static but may be easily added or deleted according to resource changes. Applications (5) and resources (10) are decoupled from the messaging system.</p> |
