Abstract

La présente invention se rapporte à un procédé et à un dispositif adaptés pour mettre en œuvre un équilibrage de charge. Dans le procédé selon l'invention : un terminal transmet une demande de résolution de nom de domaine au serveur d'un système de noms de domaine ; il reçoit une liste d'adresses IP retournée par le serveur du système de noms de domaine ; il adopte une stratégie pour sélectionner aléatoirement une adresse IP dans la liste d'adresses IP ; et il transmet une demande d'accès à un serveur de service sur la base de l'adresse IP. Selon la présente invention, comme le côté terminal adopte la stratégie aléatoire, la distribution équilibrée sur le côté serveur devient inutile avec le procédé et le dispositif selon l'invention, ce qui permet de réduire la charge.
