Technical Impacts

  • RLive [EuroSys’26] has served in the ByteDance CDN system for over 3 years, supporting hundreds of millions of daily live-streaming viewers. RLive has tripled delivery capacity, reduced rebuffering events by 14.9-20.1%, and improved video bitrate by 10.2-11.4%.
  • LiveMap [CoNEXT’25] has been deployed in the BiliBili CDN system since September 2023, serving tens of millions of daily users of both VoD and live streaming. It has saved bandwidth costs by up to 42.18% (equivalent to millions of dollars annually) and decreased access latency by 20.26%.
  • The flow scheduler in Oceanus [CoNEXT’25] has been deployed in the Alibaba Cloud CDN system, reducing CDN access latency (RTT) and improving scheduling mapping stability.
  • MARC [ATC’25] has been deployed in Taobao 3D cloud rendering system. It has served over 1 million sessions, reducing session freeze rates by 71% and increasing user interaction time by 20%.
  • JitBright [TOMM’25; NOSSDAV’24 Best Paper] has been deployed in the Taobao 3D cloud rendering system. It has served over 591,000 sessions and increased the proportion of sessions that met the MTP latency requirement of less than 150 ms by 6% to 27%.
  • Patent CN116436865A (part of Chorus [MobiCom’24]) has been applied in the Taobao RPC system (XQUIC) to control multipath reinjection. XQUIC
