1. A master device for performing flow control of multihop communication in a network including a plurality of nodes, the master device being configured to:
- allocate, to each node using second service, a time obtained by subtracting, from a frame period of the network, a total one frame transmission time of each node, used for first service, as a one frame transmission time used for second service having a priority set lower than that of the first service; and
determine whether to allow participation of a node requesting participation in the network anew, based on the frame period, a one frame transmission time used for first service, and a guaranteed one frame transmission time used for second service,wherein the master device is configured to allow participation of the node if the frame period>
Σ
(one frame transmission time used for first service per node)+Σ
(guaranteed one frame transmission time used for second service per node) is satisfied.

Abstract
A node is included in a communication control system including a plurality of nodes 31, and a master device 30 for performing flow control of multihop communication in a network including the plurality of nodes 31. To the node 31 in use of second service, a time obtained by subtracting, from a frame period of the network, a total one frame transmission time of each node, used for first service is allocated as one frame transmission time used for second service having a priority set lower than that of the first service.

10. A non-transitory computer readable recording medium in which a communication control program is recorded, the communication control program is installed in a computer for performing flow control of multihop communication in a network including a plurality of nodes, the communication control program causing a computer to:
-
allocate, to each node using second service, of a time obtained by subtracting, from a frame period of the network, a total one frame transmission time of each node, used for first service, as a one frame transmission time used for second service having a priority set lower than that of the first service; and determine whether to allow participation of a node requesting participation in the network anew, based on the frame period, a one frame transmission time used for first service, and a guaranteed one frame transmission time used for second service, wherein the communication control program causes the computer to allow participation of the node if the frame period>
