DCP-EW: Distributed Congestion-Control Protocol for Encrypted Wireless Networks

Abstract— VCP suffers from a relatively low speed of convergence and exhibits biased fairness in moderate bandwidth high delay networks due to utilizing an insufficient amount of congestion feedback. Our previous work Double-Packet Congestion-control Protocol (DPCP) addressed this problem by increasing the amount of the feedback distributed over two ECN bits in the IP header of a pair of packets. However, DPCP faces deployment obstacles in encrypted wireless networks due to the fact that it relies on partial information in the TCP header and the TCP header information is lost when crossing encryption boundaries. Furthermore, wireless networks are characterized by both error- and congestion-caused loss. Our previous work has revealed that the efficiency of DPCP, and for that matter any congestion control protocol, over wireless networks may be reduced as the result of not being able to differentiate between two types of loss. In this paper, we propose an alternative congestion contr...
