It supports transfer of delay sensitive real-time video and audio material using SRTP, as well as transfer of arbitrary data using SCTP. The congestion control algorithms of these two transport protocols are optimized for two different goals: While RTP tries to keep delays minimal, SCTP tries to maximize throughput. This contradiction leads to an excess in queuing delay and ultimately a deterioration of user experience when these protocols are used simultaneously. The work at hand introduces a novel algorithm for coupling the two transport protocols in order to achieve both goals at the same time. We have implemented our algorithm in the OMNeT++/INET simulation environment and present results to prove that the algorithm works as intended. We found that our approach keeps queuing delays in tolerable regions for all link configurations tested, enabling the concurrent use of WebRTC Media Channels and SCTP Data Channels independent of the queue length of the access router.
