A method for reducing data center communication load and energy consumption

Abstract

The invention discloses a method for reducing communication loads and the energy consumption of a data center. The method includes enabling a dispatching center to compute an initial placement sequence of virtual machines according to an expenditure matrix and a service demand matrix; configuring service communication data to corresponding switchboards and links according to bandwidth constraint conditions and acquiring an initial service routing information table; judging whether an execution communication duration of a task carried by a current virtual machine exceeds a communication duration threshold value or not, and migrating the current virtual machine into a target physical machine logically closest to a target virtual machine if the execution communication duration of the task carried by the current virtual machine exceeds the communication duration threshold value; enabling the dispatching center to judge whether all the virtual machines carried with tasks with execution communication durations exceeding the communication duration threshold value are migrated or not, enabling the dispatching center to update the initial placement sequence of the virtual machines and the initial service routing information table if all the virtual machines carried with the tasks with the execution communication durations exceeding the communication duration threshold value are migrated, and closing the switchboards which are not used by the data center. The method has the advantages that network information dynamic perception and feedback regulation functions can be realized, services with the communication durations exceeding the duration threshold value are reasonably distributed, the usage amount of the switchboards is reduced, and the purpose of saving energy for the data center is achieved.

Description

technical field [0001] The invention relates to the technical field of computer applications, in particular to a method for reducing communication load and energy consumption of a data center. Background technique [0002] In the context of cloud computing sweeping the world and the development of cloud computing industry surging, energy consumption of cloud computing data centers has become one of the topics of concern in academia and industry in recent years. Japan's Ministry of Economy, Trade and Industry (METI) predicts that global IT energy consumption will increase five-fold by 2025 and increase twelve-fold by 2050. A large amount of energy consumption makes IT companies like Google, Microsoft, and Facebook spend millions of dollars in electricity bills every year, and the energy consumption of data center network equipment is also quite huge. According to statistics, the energy consumption of network equipment in the data center accounts for 10%-20% of the total ener...

Problems solved by technology

However, this method does not take advantage of the current cloud computing data center (that is, virtual machine migration technology), does not make full use of the resources of the cloud computing data center, and has a single control method

[0006] 2) Meng et al. proposed a new problem for energy saving of network equipment - traffic-based virtual machine allocation problem (TVMPP) [2] , but its solution does not consider link capacity constraints, which may lead to the introduction of virtual machine allocation methods with congested links into the data center

[0007] 3) Shirayanagi et al. proposed a Honeguid solution [3] , but this method needs to add a spanning link between the physical machine and the switch, which increases the probability of failure in the data center
