[SoonyangZhang]

The quic protocol may be a more attractive protocol for reliable udp transmisison. Of cource, the quic implementation is daunting in consideration of the large size of its codebase. But there is an alternative option implemeted by facebook https://github.com/facebookincubator/mvfst/tree/master/quic. The most important fature is the newer congestion control algorithm BBR. Just a suggesstion. The author can try it.
