Embodiment Construction

[0015] The present invention will be further described in detail below in conjunction with the accompanying drawings. Such as figure 1 As shown, each network unit in the line terminal is provided with two First-In-First-Out (FIFO) queues, and they are respectively designated as high-priority and low-priority queues. Upstream data includes scheduling data and non-scheduling data, and downstream data includes real-time data and non-real-time data. Real-time packets (delay-sensitive packets) are buffered in high-priority queues, and non-real-time packets (delay-insensitive packets) are buffered in low-priority queues. Also based on the queuing delay, our downstream packet scheduling process is carried out both inter-frame and intra-frame.

[0016] At the inter-scheduling level, line terminations can determine the order of tasks polled. At the beginning of a polling cycle, the line termination will examine the downstream queues to identify network elements. If a real-time pack...

Abstract

The invention relates to an energy-saving scheme of Ethernet, in particular to a downstream packet scheduling Ethernet energy-saving scheme based on a hybrid sleep mode. The downstream packet scheduling Ethernet energy-saving scheme mainly comprise downstream packet scheduling and a hybrid sleep mode. A downstream packet scheduling algorithm combines an inter-frame scheduling algorithm and intra-frame scheduling algorithm to ensure that delays of downstream packets can meet requirements. An Ethernet energy-saving mode adopts a hybrid sleep mode, which includes a deep sleep mode of a low-load Ethernet network unit and independent sleep modes of a transmitter and a receiver, so as to ensure the minimum energy consumption of idle periods of Ethernet. In this way, Ethernet can be in a low energy consumption mode for a long time in idle periods so as to be reduced in energy consumption. The scheme of the invention is mainly applied to energy conservation of Ethernet with a large scale network scale and a large network topological structure.
