A data packet provided with address information (VPI, VCI) is received at an input connection (5a, 5b, 5c, 5d) of a node (1). The address information is broken down (S1) into an initial section and a subsequent section. The initial section is used (S2) as an address for addressing a reference table (15), containing entries which define the manner in which the subsequent section is to be analysed, in order to find routing information for the data packet. The entry can be a reference to a connection table, containing the routing information (S4, V), or to a further entry in the reference table (S4, Z). |
