System for setting each transfer module in a network device into one of a plurality of standby states based upon the level of traffic

摘要

This invention provides a data transfer control device for carrying out data transfer using a plurality of transfer resources. The data transfer control device comprises a transfer resource management portion that set the plurality of transfer resources to either one of a transfer-enabled state whereby data transfer is enabled and a plurality of standby states on the basis of a load on the data transfer control device and that manages the plurality of transfer resources so as to assume the set operating status; and a load distribution portion that distributes the data to transfer resources that have been set to the transfer-enabled state. The plurality of standby states are states which data transfer is disabled and which mutually differ at a minimum in terms of at least one of power consumption level and transition time to the transfer-enabled state.

1. A data transfer control device connected to a network, the data transfer control device comprising:
a network interface coupled to a network; and transfer resources for a data transfer set, based on traffic of data received from the network via the network interface, to either one of a transfer-enabled state whereby data transfer for transmitting a received frame data from the network via the network interface is enabled and a plurality of standby states in which data transfer is disabled and which mutually differ at a minimum in terms of at least one of power consumption level and transition time to the transfer-enabled state, wherein a first transfer resource is set, based on the traffic of data received from the network via the network interface, in the transfer-enabled state, a second transfer resource is set, based on the traffic of the data received from the network via the network interface, in one of the plurality of standby states, and a third transfer resource is set, based on the traffic of the data received from the network via the network interface, in another of the plurality of standby states that differs from the standby state of the second transfer resource in terms of at least one of power consumption level and transition time to the transfer-enabled state.
