Example Embodiment

[0026] The embodiments of the present invention will be described in detail below. Examples of the embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals indicate the same or similar elements or elements with the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary, and are only used to explain the present invention, and cannot be construed as limiting the present invention.

[0027] In order to better explain the present invention, first introduce the deployment mode of the data center network. figure 1 A schematic diagram of the deployment of the data center network is shown. Such as figure 1 As shown in the figure, the data center servers are interconnected by a large number of switch devices, and their connection methods can adopt a variety of typical data center network topologies. Among them, the red switch indicates that the switch device is in working state and is b...

Abstract

The embodiment of the invention discloses an energy-saving routing method for a network of a data center, which comprises the following steps of: calculating basic routing and basic throughput rate of the network; calculating network load born by each switch in the network, deleting the node loaded most lightly, and generating new network topology; calculating corresponding network routing and network throughput rate under the topology; judging whether the network throughput rate is smaller than the network throughput rate threshold; if judging that the network throughput rate is more than or equal to the network throughput rate threshold, repeating the steps until the network throughput rate is smaller than the network throughput rate threshold, wherein the corresponding network routing at the moment is energy-saving routing, and the unused switch in the routing is closed or set into a sleep mode. The embodiment of the invention also discloses an energy-saving routing device for the network of the data center, which comprises a calculation module, a switch deleting module, a judging module and an energy-saving module. The method and device can greatly reduce the electric energy consumed by network equipment, and bring great benefit to managers in the data center.

Description

technical field [0001] The invention relates to the technical field of the Internet, in particular to an energy-saving routing method and device for a data center network. Background technique [0002] A data center, also known as a server farm, is a facility used to house computer systems and related components, such as telecommunications and storage systems. Typically it includes redundant and backup power supplies, redundant data communication links, environmental controls (eg air conditioning, fire extinguishers) and safety equipment. [0003] Current data centers contain tens of thousands of switches and servers running data-intensive application services. The goal of the data center network is to interconnect a large number of data center servers and provide effective and fault-tolerant routing services for upper-layer applications. In order to overcome the problems of high implementation cost, poor scalability and single point of failure caused by the tree topology ...
