Method for reducing power consumption of RSTP looped network and application thereof

Abstract

The invention discloses a method for reducing power consumption of an RSTP looped network and an application thereof. The invention provides the method for reducing power consumption of the RSTP looped network. Provided is a network system comprising a network device (e.g., a switch) that fully supports an RSTP protocol and satisfies the IEEE 802.3 az EEE standard, only a BPDU message specified byan RSTP protocol is forwarded in a blocked redundant link, and a specified port state is set to be a Discharging blocking state and does not forward network messages which are finally discarded due to the fact that a receiver MAC is in the Discharging blocking state. By means of the method, the utilization rate of the redundant link is greatly reduced, PHYs, meeting the IEEE 802.3 az EEE standard, at the two ends of the redundant link are made to be in a sleep state in most of time, and therefore power consumption of network use is reduced.

Description

technical field [0001] The invention relates to the technical field of communications, in particular to a method for reducing power consumption of an RSTP ring network and an application thereof. Background technique [0002] With the continuous expansion of the Ethernet scale, the number of switching devices in the network is increasing, and the network communication rate is increasing, and the power consumption of the equipment is also increasing rapidly. How to reduce the power consumption of Ethernet has become a research hotspot in the field of data communication. In some specific networking environments, such as battery-powered or airborne networking environments, the significance of reducing Ethernet power consumption is far more than energy saving. It can also achieve lower heat dissipation requirements and lighter equipment weight. Experiments have shown that when the Ethernet PHY works at 1Gbps, the link power consumption is about 0.5W, and at 10G, the power consu...

AI Technical Summary

Problems solved by technology

[0005] In order to solve the technical problem that when the existing standard RSTP protocol builds a ring network, the PHY of the blocked link will be frequently woken up to send and receive useless data, and thus cannot sleep, resulting in the inability to reduce energy consumption. Network power consumption method, which can greatly reduce the utilization rate of redundant links, so that the PHYs at both ends of the redundant link are in a sleep state most of the time, thereby effectively reducing the power consumption of the network
