Abstract: In a known communication system, synchronous and asynchronous traffic is exchanged between stations using a common communication path, wherein the communication system includes a complicated controlling mechanism for controlling fair allocation of asynchronous traffic. A communication system as disclosed herein includes a simple fairness mechanism for fair allocation of asynchronous traffic to the stations without a scheduler being necessary. To this end, the communication system exchanges information between the stations via the communication path in a frame of synchronous time slots and an asynchronous time slot, the synchronous time slots including an access bit for demanding access to the asynchronous time slot. All stations monitor all access bits of the other stations and set their own access bit in accordance with a set of fairness rules.
