Abstract

Background. The combination of secure routing and hard QoS is a worthwhile topic that involves designing and implementing network protocols and systems that can provide high performance and robust protection for data flow due to shared goals. Secure QoS routing over disjoint paths is a challenging problem that requires balancing the trade-off between network security and bandwidth guarantees. Objective. This article investigates a mathematical model that can address secure QoS routing by formulating it as an optimization problem with a linear objective function and linear or bilinear constraints. The objective function aims to minimize the paths compromise probability, while the constraints ensure that the total bandwidth of the paths meets the QoS requirements. Methods. We use computer simulation of hard QoS and security with disjoint path routing. Also we use mathematical programming methods in order to describe secure QoS routing. Results. The article presents a numerical study of the model using different scenarios and parameters. The results show that the model can effectively provide secure QoS routing over disjoint paths with a high bandwidth guarantee level and a low compromise probability. The work analyses the sensitivity of the solutions to the QoS requirements and reveals that there is usually some margin in the bandwidth provision. Conclusions. The proposed model is a promising tool for secure QoS routing over disjoint paths in various network environments.
利用不相交路径路由优化硬 QOS 和安全性
背景。安全路由和硬 QoS 的结合是一个有价值的课题,它涉及设计和实施网络协议和系统,从而为共享目标的数据流提供高性能和稳健的保护。不相交路径上的安全 QoS 路由是一个具有挑战性的问题,需要在网络安全和带宽保证之间进行权衡。 目标。本文研究了一个可解决安全 QoS 路由问题的数学模型,将其表述为一个具有线性目标函数和线性或双线性约束的优化问题。目标函数旨在最小化路径妥协概率,而约束条件则确保路径的总带宽满足 QoS 要求。 方法。我们使用计算机模拟不相交路径路由的硬 QoS 和安全性。此外,我们还使用数学编程方法来描述安全 QoS 路由。 结果。文章利用不同的场景和参数对模型进行了数值研究。结果表明,该模型能有效地在带宽保证水平高、妥协概率低的情况下,在不相交路径上提供安全的 QoS 路由。文章分析了解决方案对 QoS 要求的敏感性,并揭示了带宽供应通常存在一定的余量。 结论所提出的模型是在各种网络环境中通过不相交路径进行安全 QoS 路由的一种有前途的工具。
