A packet header for a data packet (14) includes a routing information field for containing at least one local node identifier data which identifies one or more nodes through which the data packet is intended to be transported. The packet header further contains a pointer field containing a pointer (PTR), which pointer indicates the position of individual local node identifier data in the routing information field. The pointer is operable to be incremented at each node so as to indicate the position of data, which identifies the node to which the data packet is to be subsequently transported. |
