Quality of Experience (QoE) reflects end users’ overall experience and feeling with network services, but needs support in terms of end-to-end Quality of Service (QoS). Segment routing (SR) as a new routing paradigm can provide good end-to-end QoS guarantee, making traditional multimedia traffic routing more efficient and scalable. In this paper, we address two problems related to the new SR mechanism: enabling fine-grained end-to-end QoS routing under a complex network environment and constructing the multicast routing tree with branch node load balancing. To solve these problems, an Inaccurate information-based QoE-driven Routing algorithm (IQdR) and a Branch-aware Multicast Tree (BaMT) algorithm were proposed. Simulation test results that have compared the performance of our proposed solution against that of other algorithms show that the previous works were outperformed. Additionally, the results also show that our multicast architecture improves the scalability of the network in terms of the number of flows.

QoE-Driven Multicast Strategy with Segment Routing--一种新的多媒体流量工程范式

体验质量 (QoE) 反映了最终用户对网络服务的整体体验和感受,但需要端到端服务质量 (QoS) 方面的支持。分段路由(SR)作为一种新的路由范式,可以提供良好的端到端 QoS 保证,使传统的多媒体流量路由更加高效和可扩展。在本文中,我们解决了与新 SR 机制相关的两个问题:在复杂网络环境下实现细粒度的端到端 QoS 路由和构建具有分支节点负载均衡的组播路由树。针对这些问题,提出了基于不准确信息的QoE驱动路由算法(IQdR)和分支感知组播树(BaMT)算法。将我们提出的解决方案的性能与其他算法的性能进行比较的模拟测试结果表明,以前的工作优于其他算法。此外,结果还表明,我们的多播架构提高了网络在流数量方面的可扩展性。
