Technique for communication between a plurality of nodes

A first node that is connected to other nodes organized as a ring, having transmission resources, wherein at least one of the transmission resources is a control resource dedicated to transmitting control information and associated with at least one transmission resource, said first node comprising means for:

• receiving information relating to a reservation of a subsequent transmission window of the transmission resource received over the associated control resource;
• and
• determining the transmission resource reservation status;
• the first node further comprising means for:
• if the subsequent transmission window is reserved by a second node of the ring,
• comparing volumes of reservations of resources of the ring made by the first node and by the second node for at least one previous transmission window during a reference period;
• and
• pre-empting a reservation of the subsequent transmission window made by the second node as a function of the result supplied by the comparison means.

A communication system comprising a plurality of nodes,

• wherein each node of the plurality is connected to other nodes of the plurality,
• wherein the plurality of nodes are organized as a ring,
• wherein the communication system has transmission resources,
• wherein at least one of the transmission resources is a control resource dedicated to transmitting control information and associated with at least one transmission resource,
• wherein each node comprises means for:
• receiving information relating to a reservation of a subsequent transmission window of the transmission resource received over the associated control resource;
• determining the transmission resource reservation status;
• if the subsequent transmission window is reserved by a second node of the ring,
• comparing volumes of reservations of resources of the ring made by the second node and by the second node for at least one previous transmission window during a reference period;
• and
• pre-empting a reservation of the subsequent transmission window made by the second node as a function of the result supplied by the comparing means.

A non-transitory computer program product comprising instructions for carrying out a method of communication among a plurality of nodes organized as a ring provided with transmission resources,

• wherein at least one of the transmission resources is a control resource dedicated to transmitting control information and associated with at least one transmission resource,
• wherein the instructions are executable by a first node of the ring,
• wherein the instructions comprise instructions for:
• receiving information relating to a reservation of a subsequent transmission window of the transmission resource received over the associated control resource;
• if the subsequent transmission window is reserved by a second node of the ring,
• comparing the respective volumes of reservations of resources of the ring made by the first node and by the second node for at least one previous transmission window during a reference period;
• and
• pre-empting said reservation of the subsequent transmission window as a function of the result of the comparison step.
