Router, method for controlling router, and program

摘要

A router includes a buffer selection section for receiving a flit from an adjacent router and determining whether to store the flit on an input buffer or to store the flit on a bypass buffer. The buffer selection section executes at least one of a first control of, when a bypass process was performed, changing at least one of a transmission path and a transmission flow rate of data based on a transmission state of the router; and a second control of, when a bypass control section did not execute the bypass process, changing at least one of a transmission path and a transmission flow rate of data based on a transmission state of another first router at which data not subjected to the bypass process and data subjected to the bypass process by another second router are joined together.

1. A router usable in a data transfer system which includes a first node for transmitting data, a second node for receiving the data transmitted from the first node, and a plurality of routers for routing the data transferred between the first node and the second node via a bus; the router comprising:
an input section configured to receive an input of data; a switch configured to select a transmission path for the data input to the input section from a plurality of paths; a bypass control section configured to determine, based on a type of the data input to the input section, whether or not to perform a bypass process of outputting the data with priority; and an output control section configured to change at least one of a transmission path and a transmission flow rate of data which is not to be subjected to the bypass process and thus to control an output of the data, the output control section configured to execute a control by which when the bypass control section did not execute the bypass process, an output of the data which is not to be subjected to the bypass process is controlled based on a transmission state of another first router at which data that was not subjected to the bypass process and data that was subjected to the bypass process by another second router are joined together.
