Claim 0:
1. A method for routing a packet within a packet switching network in non-connected routing mode, implemented by a router B communicating with a router A, comprising the following steps:
receiving the packet by the router B;
reading a field, called lifetime field of the packet, intended to be decremented when passing through a router;
obtaining at least one piece of information from amongst a group of pieces of information comprising information relating to conditions for routing the packet and information relating to parameters of the packet;
sending the packet on the output interface by the router B;
determining an output interface is identical to the input interface for the packet to identify an about-turn to the router A; and
decrementing the value of the lifetime field by a pitch of predetermined value to avoid or limit the number of about-turns.
