Communication control apparatus, communication control method, and computer readable medium

A communication control method comprising:

• determining whether or not a delay is allowed, which is estimated to occur when a group allocation method is applied to a communication frame included in a communication stream, based on a result of calculating an index value of a queuing delay allowed for the communication stream and comparing the calculated index value against a threshold value to determine the result, wherein the group allocation method is for allocating a time slot for transmitting a communication frame in a unit of group of one or more communication frames having a common attribute,
• deciding, when the delay is allowed, to allocate the time slot to the communication frame included in the communication stream according to the group allocation method, and
• deciding, when the delay is not allowed, to allocate the time slot to the communication frame included in the communication stream according to a frame allocation method for allocating the time slot in a unit of communication frame;
• and
• performing calculation to allocate the time slot to the communication frame included in the communication stream according to the decided allocation method.

A non-transitory computer readable medium storing a communication control program for causing a computer to execute:

• an allocation method decision process:
• to determine whether or not a delay is allowed, which is estimated to occur when a group allocation method is applied to a communication frame included in a communication stream, based on a result of calculating an index value of a queuing delay allowed for the communication stream and comparing the calculated index value against a threshold value to determine the result, wherein the group allocation method is for allocating a time slot for transmitting a communication frame in a unit of group of one or more communication frames having a common attribute,
• to decide, when the delay is allowed, to allocate the time slot to the communication frame included in the communication stream according to the group allocation method, and
• to decide, when the delay is not allowed, to allocate the time slot to the communication frame included in the communication stream according to a frame allocation method for allocating the time slot in a unit of communication frame;
• and
• a time slot allocation process to perform calculation to allocate the time slot to the communication frame included in the communication stream according to the allocation method decided by the allocation method decision process.
