RDMA is promising for enhancing the performance of cross-datacenter (DC) services. However, deploying RDMA over wide-area networks introduces severe congestion control unfairness, primarily due to asymmetric congestion feedback delays between inter-DC flows and intra-DC flows. As a result, intra-DC flows often bear the full burden of congestion response, leading to drastically increased flow completion times (FCT). In this work, we identify two key forms of unfairness — nearsource and near-destination — depending on whether congestion occurs near the sender or receiver of inter-DC flows. Based on this, we propose THEMIS, a fairness maintenance patch for long-haul RDMA networks. To mitigate near-source unfairness, THEMIS devises a Proactive Notification Point to shorten the congestion feedback loop within a single DC. To alleviate neardestination unfairness, THEMIS introduces a Temporary Reaction Point to temporarily slow down the target inter-DC flow until the sender receives the corresponding congestion feedback. We implement an open-source prototype of THEMIS, and evaluate it on both real-world testbed and large-scale simulations. Compared to DCQCN, Annulus and BiCC, THEMIS reduces the intra-DC FCT by up to 79.2%, 63.6% and 55.6%, and decreases overall FCT by up to 61.2%, 31.9% and 59.5% respectively.
