A data processing network consists of a number of data processing nodes 20, i.e. computers, with an interconnection network consisting of dedicated connections and switched connections eg dial-up lines. Each node includes a connection manager 24 which, when requested, selects and sets up connections over the network, performing the necessary dial-up operations in respect of switched connections. The provision of a connection manager removes the need for programs that require to transfer messages to other nodes to know whether the connections to those nodes are dedicated or switched. The connection manager also terminates the connection when requested. <IMAGE> |
