A method for removing a member of a Link Capacity Adjustment Scheme (LCAS) from a sink includes: notifying, by the sink, a source that a member is in a REMOVE state after receiving a remove command; determining, by the sink, whether a notification response is received; if the notification response is not received, keeping the member in the REMOVE state, keeping reading payload from the member, and waiting for the notification response; if the notification response is received, moving the member to an IDLE state. Embodiments of the present invention also provide an apparatus and a state machine at the sink. A REMOVE state at the sink is added for each member. The method and the state machine provided by embodiments of the present invention guarantee a synchronous modification of the bandwidth at the source and the sink, thereby guaranteeing no hit on the traffic.

L'invention concerne une méthode d'implémentation de la suppression d'un participant par le côté collecte de LCAS comprenant que : A. Le côté collecte informe le participant à supprimer de se mettre en état de suppression après avoir reçu la notification de suppression de participant ; B. Le côté collecte détermine si la réponse d'information du côté source a été reçue ; si non, le participant à supprimer conserve l'état de suppression et attend, la charge utile continuant à être lue par le participant à supprimer ; si oui, l'état du participant à supprimer passe à l'état INACTIF. L'invention concerne également une machine côté collecte d'implémentation de ladite méthode. Un état enlever de l'état du participant est nouvellement introduit côté collecte, qui permet au côté collecte d'arrêter de lire les charges utiles du participant à supprimer, le côté source arrêtant de mapper la charge utile avec le participant à supprimer et l'ajustement de la bande passante côté source et de la bande passante côté collecte s'effectuant simultanément de façon à ce que la charge utile ne soit pas endommagée.
