“…Some works had also considered the impact of switches on load balancing, such as SAB [37] and Fincher [38]. SAB utilized the characteristics of that the switch buffer pool, usually much larger than the round-trip delay bandwidth product in the data center network.…”

Long flow detection and load balancing are crucial techniques for data center running and management. However, both of them have been independently studied in previous studies. In this paper, we propose a complete solution called Sonum, which can complete long flow detection and scheduling at the same time. Sonum consists of a software-defined synergetic sampling approach and an optimal network utilization mechanism. Sonum detects long flows through consolidating and processing sampling information from multiple switches. Compared with the existing prime solution, the missed detection rate of Sonum is reduced by 2.3%–5.1%. After obtaining the long flow information, Sonum minimizes the potential packet loss rate as the optimization target and then translates load balancing into an optimization problem of arranging a minimum packet loss path for long flows. This paper also introduces a heuristic algorithm for solving this optimization problem. The experimental results show that Sonum outperforms ECMP and Hedera in terms of network throughput and flow completion time.

“…Several studies report fairness issues in DC networks such as TCP Outcast problem [7]. For example, data center TCP (DCTCP) [8] and SAB [9] have been proposed to solve this problem. DCTCP employs a threshold on switches and informs the TCP sender about congestion condition by using a marking algorithm when the switches' buffer size exceeds the threshold.…”

Yusuke ITO †a) , Student Member, Hiroyuki KOGA †b) , Member, and Katsuyoshi IIDA † †c) , Senior Member SUMMARY Cloud computing, which enables users to enjoy various Internet services provided by data centers (DCs) at anytime and anywhere, has attracted much attention. In cloud computing, however, service quality degrades with user distance from the DC, which is unfair. In this study, we propose a bandwidth allocation scheme based on collectable information to improve fairness and link utilization in DC networks. We have confirmed the effectiveness of this approach through simulation evaluations.

“…The diverse bandwidth requirement of tenants is considered in the method, and tenants are given flexibility to assign different bandwidths for the user-opted applicationspecific VM. The sharing allocating switch buffer (SAB) for data centers was also proposed [16]. SAB is a transport protocol for bandwidth delay products (BDP).…”

Maintaining the bandwidth across a data center to meet the service level agreement is a major challenge for network administrators. If the bandwidth is not scheduled according to application requirements, the applications will be executed with increased or decreased provisioning or moved to other data centers. Hence, we developed a bandwidth scheduling algorithm that operates according to application requirements and partitions the available bandwidth to accommodate the available traffic. We simulated this algorithm with the SimPy tool and found that the proposed algorithm performs better than the general allocation and partition schemes.
