摘要： A communication network comprises a head-end and a plurality of network terminations coupled thereto through a shared communication channel, which is accessed by a protocol having one or more dedicated slots wherein upstream data cells are contained, which may collide in a transmission wherein two or more network terminations try to access the shared communication channel practically simultaneously. Herein the protocol is arranged such that the one or more dedicated slots precede the moment whereon the first next downstream transmission is started to be prepared by the head-end. In that case actual information in the dedicated slots can be fed back without substantial delay to the network terminations in order to provide them by return with actual contention information.

摘要： A method and system of transmitting messages include requesting to submit a first request for transmitting a first message and to submit a second request for transmitting a second message until there is no first collision detected between the submitted first and second requests upon receipt of the submitted first and second requests. Before there is no first collision detected between the submitted first and second requests, it is requested to submit a third request for transmitting a third message and to submit a fourth request for transmitting a fourth message. However, requesting to re-submit the third request for transmitting the third message and to re-submit the fourth request for transmitting the fourth message if a second collision is detected between the submitted third and the second requests upon receipt thereof is delayed until there is no first collision detected between the submitted first and second requests.
