摘要:

网络拥塞和数据包丢失给视频流带来了越来越大的挑战。尽管研究努力使视频编码方案对有损网络条件有弹性,但转发设备尚未考虑监视分组内容以优先化分组并最小化分组丢失对视频传输的影响。在这项工作中,我们主张在网络中的计算采用丢包算法和网络中的硬件模块来设计一个解决方案,用于改善拥塞网络中的内容感知视频流。结果表明,我们的方法可以减少内预测的数据包丢失超过80%,可以忽略不计的资源使用和性能成本。

英文摘要:

Network congestion and packet loss pose an ever-increasing challenge to video streaming. Despite the research efforts toward making video encoding schemes resilient to lossy network conditions, forwarding devices have not considered monitoring packet content to prioritize packets and minimize the impact of packet loss on video transmission. In this work, we advocate in favor of in-network computing employing a packet drop algorithm and an in-network hardware module to devise a solution for improving content-aware video streaming in congested network. Results show that our approach can reduce intra-predicted packet loss by over 80% at negligible resource usage and performance costs.
