The invention relates to a computer implemented method of identifying a next hop from a focus device in a path of interconnected devices including switching and routing devices, wherein a switching device operates according to a switching address protocol and a routing device operates according to a routing address protocol, the method implemented at a management computer having a query path to the interconnected devices and comprising: for a focus device which is configured to receive traffic addressed to a terminal destination and to act as a routing device for the traffic, dispatching a query message containing a query key based on a destination identifier for the terminal destination from the management computer to the focus device to identify the next routing address for traffic addressed to the terminal destination; receiving a result message containing a new routing address which is the next routing address; and ascertaining from the new routing address the corresponding switching address which is the switching address for switching traffic at a switching device in a direction to the terminal destination, wherein the switching address is usable in a query key for a query directed to a focus device which is a switching device. |
