Title: METHOD OF FORWARDING IN A MULTI-HOP ACCESS NETWORK
Abstract:
Method of forwarding executed by a node of a multi-hop access network, said node comprising a plurality of output tunnels, the method of forwarding comprising; a step of receiving a data packet of a multimedia stream, a step of processing said data packet by a scheduler, and - after said step of processing, a step of determining at least one output tunnel from among said plurality of output tunnels, to which to transmit said data packet, by consulting a forwarding data base, characterized in that it comprises, before said processing step, a step of associating, with the data packet, at least one output tunnel and a first number representative of a quality of transmission with which the multimedia stream must be transmitted to said output tunnel, said forwarding data base comprising a record per output tunnel of said plurality of output tunnels, each record containing an aggregation identity (IDag)representing a product of prime numbers, each of said prime numbers representing a quality of transmission with which a multimedia stream must be transmitted to the output tunnel of said record, said step of determining comprising, for each record of said forwarding data base; a step (F72) of testing a condition representing the divisibility of the product represented by the identity of aggregation of the record by said at least one prime number associated with said data packet during the associating step, and when said condition is satisfied, a step (F74) of transmitting said data packet to the output tunnel of said record.
