<p>A network (10) includes devices such as computers (12(1)-12(8)), and the like, interconnected by switching nodes (11(1)-11(6)). At least some of the devices are configured to determine the topology of the network. In determining the network topology, a device operates in a series of iterations, in each iteration transmitting a request message over a path to determine whether an additional entity is present in the network. If an additional entity is present at the end of the path defined in the request message, the entity will generate a response, which is provided to the device. The device, on receiving the response, will add information concerning the entity to a network topology database. At least some the devices, as they discover additional switching nodes in the network, will attempt to configure the switching nodes. In that operation, the devices interact with the switching nodes in connection with a locking protocol to ensure that only one device attempts to configure each switching node. Each device, after it determines the network topology, and when it needs to transfer information with another device, can determine an appropriate route using the newtork topology information in its network topology database. After determining the appropriate route, the device will load routing information into the switching nodes (11(1)-11(6)) to enable them to forward messages containing the information to be transferred thereamong.</p> |
