多链路聚合宽带无线传输技术研究
首发时间:2024-03-06
摘要:采用运营商无线网络信号进行高清视频直播时,上行带宽由接入基站的所有终端共享,单个运营商提供的带宽过低并且随接入终端数随时变化,难以实现稳定的高清视频传输。本文设计了一个多链路聚合传输系统,聚合多个运营商带宽,采用多种负载均衡调度策略,实现了基于TCP协议的大容量多链路数据传输,有效提高了视频流在运营商无线环境下的上行速率,保证传输带宽的稳定性,实现了RTMP高清视频直播。

Research on Multi-Link Aggregation Broadband Wireless Transmission Technology
Abstract:When using a wireless signal from the operator for high-definition video live streaming, the upstream bandwidth is shared by all terminals accessing the base station. The bandwidth provided by a single operator is usually too low and will vary depending on the number of connected terminals, making it difficult to achieve stable high-definition video transmission. This paper presents a multi-link aggregation transmission system that aggregates the bandwidth of multiple ISPs (Internet Service Provider). By employing various load balancing scheduling strategies, it enables high-capacity multi-link data transmission based on the TCP protocol. This system effectively enhances the upload speed of video streams and ensures the stability of transmission bandwidth in operator wireless environments, implementing high-definition RTMP video live streaming.
Keywords: multi-link aggregation wireless video transmission load balancing real-time optimization
