Abstract

Exposing network information such as distances between end hosts is useful to improve the quality of experiences for network users. Network providers calculate such information based on private topology and routing data and share it with users through well-established protocols such as Application-Layer Traffic Optimization. However, it is usually not intended to expose the original model, which can face scalability, user heterogeneity, efficacy & efficiency challenges.
In this paper, we introduce NetBoost, a system that efficiently distills and differentiates ALTO-based network information to address these challenges concurrently. NetBoost significantly reduces the size of exposed network information by orders of magnitude. In particular, by utilizing a gradient boosting algorithm for classification and regression based on IP prefix matching, NetBoost provides high-order information exposure models, allowing network providers to offer differentiated services to clients with privacy-preserving. Our experimental results demonstrate that NetBoost performs effectively in resource-constrained scenarios, surpassing state-of-the-art lossy compression algorithms and achieving greater accuracy than the XGBoost gradient boosting algorithm, while maintaining a comparable compression rate. Furthermore, in simulation experiments conducted using the real-world networking software BIND, NetBoost achieved 6.96% and 5.2% higher accuracy compared to XGBoost under the same number of rules, with NetBoost’s accuracy set at 95% and 90%, respectively. Additionally, NetBoost reduced resolve time by 44.35% and 52.47%, respectively.
NetBoost:实现网络信息曝光的高效提炼和服务差异化
公开终端主机之间的距离等网络信息有助于提高网络用户的体验质量。网络提供商根据私有拓扑和路由数据计算此类信息,并通过应用层流量优化等成熟协议与用户共享。然而,它通常并不打算公开原始模型,这可能会面临可扩展性、用户异构性、功效& 效率等方面的挑战。在本文中,我们介绍了 NetBoost 系统,它能有效地提炼和区分基于 ALTO 的网络信息,以同时应对这些挑战。NetBoost 能将暴露的网络信息的规模大幅缩小。特别是,通过利用基于 IP 前缀匹配的梯度提升算法进行分类和回归,NetBoost 提供了高阶信息暴露模型,使网络提供商能够在保护隐私的前提下为客户提供差异化服务。我们的实验结果表明,NetBoost 在资源受限的情况下表现出色,超越了最先进的有损压缩算法,比 XGBoost 梯度提升算法获得了更高的精度,同时保持了相当的压缩率。此外,在使用真实世界网络软件 BIND 进行的模拟实验中,在规则数量相同的情况下,NetBoost 的准确率分别为 95% 和 90%,比 XGBoost 高出 6.96% 和 5.2%。此外,NetBoost 还将解析时间分别缩短了 44.35% 和 52.47%。
