【摘要】：为了在嵌入式终端多应用之间合理分配有限的网络带宽资源,提出一种嵌入式终端多应用网络资源分配协议。根据应用特性对网络数据包进行分类,结合实时探测的可用带宽,为每种类型数据包分别添加不同的延迟时间,依据延迟大小调度数据包。将该协议应用于实际IP机顶盒中,在同时运行HTTP流媒体应用和FTP下载应用的环境中,能够优先保证前台流媒体应用的流畅播放。实验结果表明,该协议在多应用运行环境下,能够优先满足用户关注度高的应用网络带宽需求,实现了网络资源在嵌入式终端上的合理分配。
[Abstract]:In order to reasonably allocate the limited network bandwidth resources among multiple applications of embedded terminals, a protocol of multi-application network resource allocation for embedded terminals is proposed. According to the application characteristics, the network data packets are classified, combined with the available bandwidth of real-time detection, different delay times are added to each type of data packets, and the packets are scheduled according to the size of the delay. The protocol is applied to the IP set-top box, and in the environment of both HTTP streaming media application and FTP download application, the smooth playback of foreground streaming media application can be guaranteed first. The experimental results show that the proposed protocol can give priority to the application bandwidth requirements with high user attention in multi-application environment and realize the rational allocation of network resources on embedded terminals.
