Communication control method, communication control apparatus and program

A communication control apparatus for controlling communication between connection apparatuses, the communication control apparatus comprising:

• a processor;
• and
• a memory including computer program code, where the memory and the computer program code are configured, with the processor, to cause the communication control apparatus to:
• obtain monitor data that is a blocking rate at optical line setup in an optical line switching network, an amount concerning flows transferred by the connection apparatuses to an electric packet network, a buffer utilization state in telecommunication devices within the electric packet network, or packet transfer latency or a packet dropout rate in telecommunication devices within the electric packet network, wherein the connection apparatuses are connected through the optical line switching network and through the electric packet network, and each of the connection apparatuses is responsible for one or a plurality of devices;
• and
• change, based on the monitor data, a first threshold for distinguishing a first flow to be transferred by the connection apparatus through the optical line switching network from a second flow to be transferred by the connection apparatus through the electric packet network, wherein the first threshold is to identify, as the first flow, a flow that has a size exceeding the first threshold and identify, as the second flow, a flow that has a size that is equal to or less than the first threshold.

A communication control apparatus for controlling communication between connection apparatuses, the communication control apparatus comprising:

• a processor;
• and
• a memory including computer program code, where the memory and the computer program code are configured, with the processor, to cause the communication control apparatus to:
• determine whether a flow rate of a flow that is transferred through an optical line set between connection apparatuses in an optical line switching network is equal to or less than a threshold, wherein the connection apparatuses are connected through the optical line switching network and through an electric packet network, and each of the connection apparatuses is responsible for one or a plurality of devices;
• and
• in case where the flow rate of the flow is equal to or less than the threshold, cause to disconnect the optical line and cause a flow transmission source of the connection apparatuses to transmit packets relating to the flow through the electric packet network.
