Abstract
A packet routing apparatus holds at the least one policy condition, and at the least one label corresponding to the respective policy condition. The packet routing apparatus receives a packet, and determines whether any layer information included in the packet information matches any policy conditions. If at the least one layer information matches any policy condition, a label corresponding to this policy condition is extracted. The packet routing apparatus attaches the label to the packet and transmits the packet.
