In a network system, a client device is connected to the network via a controller that enables a user of the client device to carry out a task using one or more services available on the network. The controller ( 10 ) has a service discoverer ( 12 ) that discovers services at locations on the network (N) and a task manager ( 14 ) that controls the carrying out of tasks using services discovered by the service discoverer ( 12 ). The controller ( 10 ) also has a service publisher ( 13 ) that, as a result of the discovery of a service by the service discoverer ( 12 ) makes that service discoverable by other controllers ( 10 ) connected to the network, thereby allowing those other controllers to discover and access that service or services via that controller. |
