低时延技术的九大绝招
1.传输技术,端管边云协同提供端到端低时延方案

- 多径接入:端侧WIFI、LTE同时工作,云侧部署代理网络传输对应用开发者透明,简化开发复杂度;
- 无线加速:统一支持中国移动、联通、电信全国各省用户加速,统一支持5G切片、 MEC下沉、4/5G QoS加速
- 自建骨干网:节点全球覆盖、区域专线互通、运营商接入网络一-跳接入;
- 控制面:基于全球网络质量状态提前预测和实时更新路由
- 数据面:分段重传和冗余传输,多路径并行传输
2.创新的RTC端-网协同能力, 无线网络拥塞场景减少卡顿22%

3.多径接入,Wifi与4G/5G通讯能力共享,终端更快接入边缘节点
- 音频选用冗余模式,双链路互补;视频选用动态主备模式,自动选择优质链路;
- 开启WIFI+LTE或WIFI+ 5G双通道模式,在弱网环境下(如机场、商场等网络信号较差的场景)时延改善最高可达61%。

4.弱网对抗算法,自适应复杂网络,快速感知网络状态,避免服务器超发导致的雪崩效应,从而保证弱网低时延体验

5.AI预测和智能路由,突破跨域通信路由的挑战
- 全景测量:端管边云各分段各层级的网络质量探测、细粒度&低开销的测量技术
- 规律预测:利用全球网络在时间和地域上周期性、此起彼伏的变化规律,避开网络局部拥塞,提供优质链路,最大程度发挥网络性能
- 跨域控制&调度:基于AI规律预测进行智能路由调度、解决运营商自治域间存在路径迂回、丢包率高等问题

6.极致编码,在保证用户感知的前提下尽量降低媒体码率,同等网络条件下数据传输时间随之降低



7.信源信道协同编码,基于强化学习预测带宽,实现帧级别探测与码控

8.多方包转发技术,具备分段抗丢包能力,使用一套架构兼顾两方和多方传输

9.分段传输网络场景下全链路QoS协同编码
