A Load-balanced Approach to Time Efficient Resource Scheduling in SDN-enabled Data Center

Nowadays it is common for applications to run on data centers and deliver services to users. With the increase of tasks of multiple applications, it is a challenge for data center providers to make full use of the available resources, and improve task response time without too much computational cost. This paper focuses on load-balance based time efficient resource scheduling. A resource allocation architecture for SDN-enabled data center and a load-balance based resource allocation approach(LBA) are proposed. LBA is mainly used to maintain the the whole resource in a balancing state and assign appropriate resources to tasks, majorly consisting of three parts: Load-balance, VM-selection and Path-selection. Comprehensive simulation experiments are conducted to evaluate the effectiveness of LBA. Experiment results show that LBA can take full advantage of the available resources and improve task response time on the basis of load-balance, making both SLA violation rate and average cost as small as possible.
