On Mobile Video Streaming with Statistical Performance Guarantee
在3G/4G移動網絡部署的推動下,移動視頻流已經成為移動互聯網的主要應用之一。由於移動通信網絡帶寬的內在波動,業內人士以及研究人員已經開發出許多自適應流算法以應對這樣的波動來提高流性能。目前的流算法通常都是被設計和調整以期望在所有的網絡中都可以工作的很好。雖然考慮到廣泛差異的網絡類型和特性,從覆蓋不良的3G網絡到可以提供100+Mbps帶寬的LTE網絡,目前的流算法在不同網絡和系統條件下會表現出不同的性能也不足為奇,但是這種缺乏可預測性和一致性的性能表現給服務提供商帶來了極大挑戰,它使得為用戶提供始終如一體驗的視頻流服務就算是可能的,也是非常困難的。 === 本文打破了傳統的一刀切的自適應流算...
