【摘要】：為了在嵌入式終端多應(yīng)用之間合理分配有限的網(wǎng)絡(luò)帶寬資源,提出一種嵌入式終端多應(yīng)用網(wǎng)絡(luò)資源分配協(xié)議。根據(jù)應(yīng)用特性對(duì)網(wǎng)絡(luò)數(shù)據(jù)包進(jìn)行分類(lèi),結(jié)合實(shí)時(shí)探測(cè)的可用帶寬,為每種類(lèi)型數(shù)據(jù)包分別添加不同的延遲時(shí)間,依據(jù)延遲大小調(diào)度數(shù)據(jù)包。將該協(xié)議應(yīng)用于實(shí)際IP機(jī)頂盒中,在同時(shí)運(yùn)行HTTP流媒體應(yīng)用和FTP下載應(yīng)用的環(huán)境中,能夠優(yōu)先保證前臺(tái)流媒體應(yīng)用的流暢播放。實(shí)驗(yàn)結(jié)果表明,該協(xié)議在多應(yīng)用運(yùn)行環(huán)境下,能夠優(yōu)先滿(mǎn)足用戶(hù)關(guān)注度高的應(yīng)用網(wǎng)絡(luò)帶寬需求,實(shí)現(xiàn)了網(wǎng)絡(luò)資源在嵌入式終端上的合理分配。
[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.
