Abstract:
1. A computer-readable, non-transitory medium storing a prohibition turn determination program causing a computer to execute a process, the process comprising: calculating communication amounts of respective turns, each turn being defined as a combination of an input port and a counter output port of the input port installed in each switch along a communication path between communication apparatuses executing communication via a network including a loop structure having the plurality of switches, based on a communication amount between the communication apparatuses, the communication amount being a sum value of an amount of information sent by one communication device in a group defined as a transmission source to all communication devices in a group defined as a reception destination and an amount of information sent back from all the communication devices in the group defined as the reception destination to the communication device in the group defined as the transmission source, the calculating further calculates sum values of communication amounts of respective tentative prohibition turns; determining the tentative prohibition turn when each of the plurality of switches is used as a top switch by an Up/down method; and calculating a sum value of communication amounts of the tentative prohibition turn for each top switch, and determining the tentative prohibition turn determined corresponding to the top switch and whose sum value of the communication amounts is smallest among all the tentative prohibition turns as a prohibition turn which is not used to transmit a packet.
