Abstract
On maintient la synchronisation dans un canal de communication commun possédant des créneaux temporels de transmission désignés pour divers dispositifs d'un réseau informatique en autorisant des transmissions dans le canal hors du créneau temporel désigné d'un dispositif de réseau lorsqu'une évaluation de canal libre indique qu'un créneau temporel antérieur n'est pas utilisé pas son dispositif associé et/ou après réception d'une indication de fin de transmission d'un autre dispositif du réseau. L'évaluation de canal libre tient de préférence compte du créneau temporel de transmission désigné du dispositif dans le canal de communication par rapport à ceux d'autres dispositifs de réseau, et peut être une période temporelle résultant de la durée d'attente d'un canal libre prédéterminé ; et d'une représentation numérique du créneau temporel de transmission désigné du dispositif dans le canal de communication par rapport à ceux d'autres dispositifs de réseau. La durée d'attente de canal libre peut être spécifiée par un dispositif maître de réseau comme faisant partie du processus de connexion au réseau. Le dispositif de réseau peut être configuré de manière à construire un ou plusieurs paquets en vue d'une transmission dans le réseau avancée par rapport à son créneau temporel désigné pour permettre ces transmissions précoces.
