“…These scheduling schemes can be classified into three categories. The most widely used method for allocating bandwidth in the spatial dimension is the max-min fairness, whereby flow weights are adjusted depending on their priorities [6,9]; in the time dimension, some systems [10,11] reserve the bandwidth for future resources; in the storage dimension, some systems [12,13] adopt the store-and-forward method, since most current systems are separated by fixed bandwidth. When online traffic is idle at a low valley, excess bandwidth cannot be released to offline traffic.…”

Large companies are increasingly providing their services over interdomain data centers. Such large-scale wireless communication networks carry various applications, including both online time-sensitive services and offline bandwidth-sensitive services. These applications share the same physical links but have different bandwidth requirements at different time, making the coscheduling problem a key challenge in improving the overall network utility. Most existing commercial systems reserve peak value bandwidth for online time-sensitive services to ensure the quality of service and use the leftover bandwidth to transmit offline data in a best-effort manner. Such systems cannot obtain high link utilizations because of the nonstationarity of online traffic. To solve this problem, we present a dynamic isolated transmission (DIT) system in this paper, where a sliding- k algorithm is designed to predict online traffic, and a bottleneck bypass routing scheme is proposed to schedule the mixed traffic in a shared inter-DC wireless communication network. We conduct a series of experiments in an experimental inter-DC wireless communication network to analyze for efficient network operation of the DIT and compare its performance with typical existing fix-bandwidth-based solutions including Microsoft’s SWAN. The results show that DIT outperforms existing solutions, improving the interdomain link utilization by 18% and the intradomain link utilization by 65%.
