COMMUNICATION SYSTEM AND NETWORK CONTROL DEVICE

摘要

A communication system is capable of re-examining an allocated communication path and a reserved communication path and implementing a rapid service provision in which a resource utilization efficiency is high without an interruption of service or an abrupt deterioration of quality when a reserved communication path is created in advance, and a reserved communication path is allocated according to an allocation request of a user. A communication path with quality assurance of data communication is implemented in a communication network with a communication path calculation device having a communication path managing unit and communication path calculating unit. The communication path managing unit manages reserved communication paths with quality assurance constructed based on a quality assurance communication path construction request of a communication system administrator and a use communication path allocated from among the reserved communication paths according to the quality assurance communication path allocation request of the communication network user.

主权项

1. A communication system in which a communication path with quality assurance of data communication is implemented in a communication network including a communication device and a communication path calculation device as a component,
wherein the communication path calculation device includes an input unit, an output unit, a storage unit, a communication path managing unit, and a communication path calculating unit, the communication path managing unit manages reserved communication paths with quality assurance constructed based on a quality assurance communication path construction request of a communication system administrator input to the input unit and a use communication path allocated from among the reserved communication paths according to the quality assurance communication path allocation request of the communication network user input to the input unit, and the communication path calculating unit gives a priority to the reserved communication path and the use communication path, and reconfigures the reserved communication path and the use communication path in a priority order.
