Data channel considerations for RTCWeb

Browser-to-browser communication is a hot topic in the network research community. The goal of developing and standardizing RTCWeb for real-time communication is to enhance the communication experience over the Internet. The RTCWeb protocol stack provides a service for several use cases, which includes media as well as non-media data transfer. Therefore, it adapts some established protocols like SCTP for a new common goal. Since real-time communication comes with the inherent need for low end-to-end delay, this article will discuss possible enhancements to SCTP that will improve the RTCWeb service in that regard.
