Patent ID: 8804706

Claim:
An information processing system comprising: information processing devices; and relay devices configured to relay data transmitted and received between the information processing devices, a relay device including: communication ports configured to transmit data between the relay devices, and processing hardware: configured to cause a first transmission/reception operation and a second transmission/reception operation to be selectively executed, the first transmission/reception operation being an operation in which data is caused to be transmitted and received at a first transmission speed in the communication ports, the second transmission/reception operation being an operation in which data divided into a plurality of data equal to a number of communication ports is caused to be transmitted and received in parallel in the number of communication ports at a second transmission speed lower than the first transmission speed, and configured to generate divided transmission data, which number of divided transmission data is equal to the number of communication ports, to cause the generated pieces of divided transmission data to be transmitted in parallel through the respective communication ports, when the second transmission/reception operation is selected.
