论文摘要
我们考虑使用操作员之间的带宽共享来增强无线网络中实时流量的交付的问题。实时流量的关键特征是必须在延迟截止日期内交付数据包才能有用。在视频和音频会议等应用程序的普及中，实时流量的丰富性很明显，这些应用程序在Covid-19期间大幅增加。我们提出了一项共享和调度策略，其中涉及与另一个运营商动态分享一个运营商的带宽的一部分。我们为该政策提供了强大的理论保证。我们还通过广泛的模拟评估了其性能，该模拟显示出使用该策略时可以实时流量的能力高达90％。我们还探讨了带宽共享的改进如何取决于共享的数量以及其他流量特征。
We consider the problem of enhancing the delivery of real-time traffic in wireless networks using bandwidth sharing between operators. A key characteristic of real-time traffic is that a packet has to be delivered within a delay deadline for it to be useful. The abundance of real-time traffic is evident in the popularity of applications like video and audio conferencing, which increased significantly during the COVID-19 period. We propose a sharing and scheduling policy which involves dynamically sharing a portion of one operator's bandwidth with another operator. We provide strong theoretical guarantees for the policy. We also evaluate its performance via extensive simulations, which show significant improvements of up to 90% in the ability to carry real-time traffic when using the policy. We also explore how the improvements from bandwidth sharing depend on the amount of sharing, and on additional traffic characteristics.
