Abstract

La présente invention concerne un procédé et un dispositif de gestion de programme de diffusion groupée et un dispositif de réseau, le procédé consistant : à recevoir N programmes de diffusion groupée, les N programmes de diffusion groupée ayant la même priorité de qualité de service (QoS), et N étant un nombre entier positif; à configurer une priorité de suppression pour chaque programme de diffusion groupée parmi les N programmes de diffusion groupée; à mapper les N programmes de diffusion groupée dans différentes files d'attente de priorité de QoS en fonction de la priorité de suppression de chaque programme de diffusion groupée, ou à supprimer un programme de diffusion groupée en fonction de la priorité de suppression de chaque programme de diffusion groupée lorsqu'une même file d'attente de priorité de QoS dans laquelle entrent les N programmes de diffusion groupée est encombrée. Le procédé de gestion de programme de diffusion groupée selon les modes de réalisation de la présente invention fournit une priorité de suppression pour des programmes de diffusion groupée, et lorsqu'une file d'attente de diffusion groupée d'un dispositif de réseau est encombrée, un programme de diffusion groupée ayant une faible priorité de suppression est de préférence supprimé de façon à garantir la qualité d'un programme de diffusion groupée ayant une priorité de suppression élevée.
