Abstract
(EN) This application discloses a communication method and a related device. The communication method includes: A first in-domain device determines an address length, where the "in-domain" refers to being in a local area network. Then, the first in-domain device receives a data packet, and extracts an address from the data packet based on the address length. Further, the first in-domain device forwards the data packet based on the address. In the technical solutions of this application, a header compression solution of a packet is not limited by a link layer transmission protocol, has a flexible operation manner, and has wide applicability. In addition, an address used in a domain in this application may be directly used for routing and forwarding, so that communication performance can be improved.
(FR) La présente invention concerne un procédé de communication et un dispositif associé. Le procédé de communication comprend les étapes consistant à : déterminer, par un premier dispositif intra-zone, une longueur d'adresse, l'« intra-zone » indiquant « dans un réseau local » ; recevoir ensuite, par le premier dispositif intra-zone, un paquet de données, et extraire une adresse du paquet de données en fonction de la longueur d'adresse ; et transmettre en outre, par le premier dispositif intra-zone, le paquet de données en fonction de l'adresse. Selon la solution technique de la présente invention, une solution de compression d'en-tête d'un paquet n'est pas limitée par un protocole de transport de couche de liaison, de telle sorte que le mode de fonctionnement est flexible et l'applicabilité est large ; de plus, dans la présente invention, une adresse intra-zone utilisée peut être directement utilisée pour le routage/transfert, de telle sorte que les performances de communication peuvent être améliorées.
