Abstract
A packet transfer scheme that applies markings at different levels to packets while they are transferred from their source to destination, in which a marking information at one level will not be lost by a marking at another level is disclosed. A node device receives packets each having a plurality of regions into which priority information can be written, and then transmits each received packet to a next hop node by writing the priority information according to criteria of the own node into one region into which the own node is allowed to write the priority information among the plurality of regions contained in each packet, while maintaining the priority information in other regions as received.
