AHG18: An introduction to the next generation media transport protocol—Media over QUIC(MoQ)
Authors: W. Ding Huawei Xiang Ma Huawei Sergey Ikonin Huawei Elena Alshina Huawei
Abstract
In this contribution, the progresses of the next generation media transport protocol, i.e., Media over QUIC(MoQ), are introduced. MoQ is designed by IETF to support a wide range of latency requirements ranging from seconds to tens of milliseconds. Its flexible priority mechanism, inherited from QUIC, ensures that critical information is transmitted preferentially, while less-critical data is dropped first during congestion—an attribute particularly advantageous for supporting Real-time Communication (RTC), especially for the ultra-low latency (ULL) application scenarios. Moreover, MoQ inherits from QUIC the capability to transmit both reliable streams and unreliable datagrams over a single connection. The abovementioned capability and MoQ’s unique hierarchical object data model bring new transmission features, and there is a new possibility to enable ULL applications if the video codec can better fit the new transmission features.

As an essence of the presentation, priority of certain parts of the stream would be matching with QUIC concepts, which is able to drop low-priority parts of the stream. Multiple levels of priority are possible, multiple streams.
