Title
A Joint Balancing Flow Table and Reducing Delay Scheme for Mice-flows in Data Center Networks
Abstract
In data center networks based on SDN, mice-flows are latency-sensitive and packet loss sensitive. Meanwhile, they account for the majority of traffic in the network, most flow rules are installed to direct the forwarding of mice-flows. According to the characteristics mentioned above, this paper proposes a joint balancing flow table and reducing delay (BFTRTD) scheme for mice-flows in data center networks to efficiently utilize limited flow tables and minimize the delay for mice-flows. In this scheme, a novel evaluation index for table balance is proposed to balance flow tables, combining with the delay of the path to initialize routes. In addition, this paper also adopts the up-to-date flow rules installation mechanism to further guarantee the transmission quality and delay of mice-flows. We evaluated the proposed BFTRTD in terms of average packet loss rate and average delay of mice-flows. Simulation results show that, compared with ECMP and DIFF-Mice, the proposed BFTRTD scheme reduces the average packet loss rate by an average of 4.5% and 5.9%, while decreases the average delay by an average of 4.1% and 4.7%, when the flow arrival rate is between 120 Mbit/min and 280 Mbit/min where network load goes from low to high.
