However, there lacks useful approaches to share the internal network resource of cloud data centers. Invalid network sharing not only degrade the performance of applications, but also affect the efficiency of data center operation. To guarantee network performance of applications and provide fine-grained service differentiation, in this paper, we propose a differentiated bandwidth guarantee scheme for data center networks. Utility functions are constructed according to the throughput and delay sensitive characteristics of different applications. Aiming to maximize the utility of all applications, the problem is formulated as a multi-objective optimization problem. We solve this problem using a heuristic algorithm: the elitist Non-Dominated Sorted Genetic Algorithm-II(NSGA-II), and we make a multi-attribute decision to refine the solutions. Extensive simulations are conducted to show that our scheme provides minimum band-width guarantees and achieves more fine-grained service differentiation than existing approaches. The simulation also verifies that the proposed mechanism is suitable for arbitrary data center architectures. <\/jats:p>","DOI":"10.1142\/s0219265913600025","type":"journal-article","created":{"date-parts":[[2014,5,29]],"date-time":"2014-05-29T04:11:27Z","timestamp":1401336687000},"page":"1360002","source":"Crossref","is-referenced-by-count":0,"title":["Differentiated Bandwidth Guarantees for Cloud Data Centers"],"prefix":"10.1142","volume":"14","author":[{"given":"YANGYANG","family":"LI","sequence":"first","affiliation":[{"name":"State Key Laboratory of Networking and Switching Technology, Beijing University of Posts and Telecommunications, Beijing 10086, P.
