Communication control system, method, and apparatus

摘要

A communication control system includes a first computer and a second computer, wherein the first computer includes a communication interface device and a first processor configured to control the communication interface device to transmit first data and first feature information indicating a feature of the first data to the second computer, and the second computer includes a memory that has a storage area allocated to store second data received from the first computer, and a second processor configured to determine whether the first feature information received from the first computer matches second feature information, indicating a feature of and calculated based on the second data stored in the storage area, and control the memory to release the storage area when the second feature information does not match the received first feature information.

1. A communication control system comprising:
a first computer; and a second computer, wherein the first computer includes:
a communication interface device; anda first processor configured to control the communication interface device to transmit first data and first feature information indicating a feature of the first data to the second computer, and the second computer includes:
a memory that has a storage area allocated to store second data received from the first computer; anda second processor configured to:
in a case of detecting that the transmission of the first data from the first computer has ended, determine whether the first feature information received from the first computer matches second feature information, indicating a feature of the received data stored in the storage area, calculated based on the second data stored in the storage area, wherein the first processor is further configured to calculate a first hash value from contents of the first data, and send the first hash value to the second computer as the first feature information, and the second processor is further configured to calculate a second hash value from contents of the second data, and control the memory to release the storage area in response to the second processor making a determination that the second hash value does not match the first hash value, the second processor notifying the first computer that the transmission of the first data has failed based on the determination prior to the second computer receiving a transmitted error indication, from the first computer, which indicates that the first data was received in error.
