METHOD FOR ENSURING ACCESS TO A TRANSMISSION MEDIUM

摘要

The present invention relates to a method for ensuring access to a transmission medium at a predetermined point in time, for transmission of a data packet. This is achieved by making one or more communication ports on which the packet is to be transmitted unavailable for conflicting traffic for a period of time that is set to expire at the desired point in time, and preparing the data packet to be transmitted as soon as said communication port again is made available.
