METHOD FOR SYNCHRONISATION IN A COMMUNICATION NETWORK AND IMPLEMENTING APPLIANCES

摘要

The invention concerns a method for synchronisation in a communication network comprising at least two buses interconnected by a wireless communication network, each bus being connected to the wireless communication network by a portal. The method consists in: determining a portal, called cycle server whose own particular clock will be used as reference for the other portals; transmitting through each portal a synchronising signal at a predetermined time with respect to the beginning of each frame and characterising each portal, said frame being defined relative to each portal particular internal clock, said synchronising signal being produced by inserting a control window; detecting by each portal the control windows of other portals and selecting one of the detected windows for synchronising a particular clock of the receiving portal with the cycle server clock, said selected window corresponding to a portal whereof the clock is already synchronised with the cycle server portal clock. The invention also concerns receiving and transmitting appliances implementing the method.
