Abstract
A method of operating a node device (20) in a network (10) of communicatively interconnected node devices wherein a node device (20) is arranged to transmit a message once in said network (10), the node device (20) comprising a host part (30) and a controller part (40). The host part (30) is arranged for maintaining a list (31) identifying messages received at the node device (20) and the controller part (40) is arranged for storing messages to be transmitted by the node device (20) in a cache buffer (41). The method comprises the steps of removing, by the controller part (40), a message from the cache buffer (41), forwarding, by the controller part (40), to the host part (30), upon removal of the message, an update message identifying the removed message, and updating, by the host part (30), based on the update message, the list of messages (31). A corresponding node device (20) arranged for performing a method according to the present disclosure and a computer program product are also presented herein.
