Resource management device, resource management system, and computer-readable recording medium

A resource management system that is a communication system including a plurality of communication devices in a network and a resource management device providing a communication service in response to a service request by using the communication devices in the network, the resource management device comprising a processor, wherein the processor executes a process comprising:

• first converting a total resource amount in the network into a first value that is a first converted result of a total amount converted by using a predetermined reference rate, the total resource amount including a transmission band amount of a communication path that is set between communication devices on the network and a number of ports of each type of a transmission band among ports of the communication devices, which are connectable with a terminal device associated with the service request;
• assigning a second value to each type of the communication service from the first value, the second value that is a second converted result of an assigned resource amount converted by using the predetermined reference rate;
• second converting a resource requesting amount of the service request into a third value that is a third converted result of a requested amount of a service request converted by using the predetermined reference rate, the resource requesting amount including a service quality between start and end points that are associated with the communication service of the service request;
• setting, determining the third value is equal to or less than the second value that is assigned to the type of the communication service of the service request, a communication service associated with the service request for the communication device on the network;
• and
• adjusting the second value of another communication service to adjust a shortage amount of the second value of the communication service, determining the third value is greater than the second value of the communication service of the service request.

A non-transitory computer-readable recording medium having stored therein a resource management program that causes a processor of a resource management device that provides a communication service in a network in response to a service request to execute a process, the process comprising:

• first converting a total resource amount in the network into a first value that is a first converted result of a total amount converted by using a predetermined reference rate, the total resource amount including a transmission band amount of a communication path that is set between communication devices on the network and a number of ports of each type of a transmission band among ports of the communication devices, which are connectable with a terminal device associated with the service request;
• assigning a second value to each type of the communication service from the first value, the second value that is a second converted result of an assigned resource amount converted by using the predetermined reference rate;
• second converting a resource requesting amount of the service request into a third value that is a third converted result of a requested amount of a service request converted by using the predetermined reference rate, the resource requesting amount including a service quality between start and end points that are associated with the communication service of the service request;
• setting, determining the third value is equal to or less than the second value that is assigned to the type of the communication service of the service request, a communication service associated with the service request for a communication device on the network;
• and
• adjusting the second value of another communication service to adjust a shortage amount of the second value of the communication service, determining the third value is greater than the second value of the communication service of the service request.
